The best online computer scanner for viruses. How to clean your laptop from viruses

Good day!

In general, lately, after all, the word “viruses” does not evoke such a terrible panic as it did 15 years ago (when some users wiped their disks with alcohol, thinking that this would protect them from the threat...). However, you should not underestimate the threat - overnight you can lose your documents, programs, and even money (if the virus can gain access to your Internet wallets).

Common Myth: If you think that your regular antivirus completely protects your system, you are mistaken!

Addition! The most dangerous viruses of the past, will history repeat itself? -

Actually, in this article I want to give a short recipe for checking and cleaning your computer from viruses and various types of malware (add-ons, advertising banners, lockers, etc.). I note that this note will also be useful for those who even know that there is a virus on their computer, but cannot remove it and clean the system.

And so, closer to the topic...

Removing “classic” viruses

The first thing you should start with is installing a modern antivirus, updating its databases and a complete scan of your PC (at least Windows and the entire system drive).

As a rule, to start a scan, it is enough to open the main antivirus window and click once on the corresponding button (as, for example, in Kaspersky Anti-Virus, see screenshot below). There is nothing special to comment on here: if viruses are found, they will automatically either be isolated or removed/cured (No settings or actions are usually required).

Scan your computer (Kaspersky Anti-Virus). Clickable

If you can't install an antivirus

It is not so rare that viruses find various ways to “block” the operation (installation) of an antivirus: for example, on an infected PC all antivirus sites may be unavailable (i.e., it simply cannot even be downloaded), the desktop may be blocked, “jump "mouse cursor, etc.

One of these viruses that has blocked the desktop (this window cannot be minimized or closed)

Important!

Do not comply with any requests from such malware. Even if you transfer the agreed amount to them, your system will not be unlocked!

In this case, you can go the following ways:

1. remove the hard drive from the PC/laptop and on which the antivirus is installed. Then scan this disk completely (cons: not all viruses will be found; there is a risk that you will infect a second PC. But if you don’t open anything from it and don’t run anything from an “infected” disk, the risk is still low) .
2. Use LiveCD(with built-in antiviruses). A LiveCD is a disk from which you can boot (that is, in fact, it is a full-fledged Windows located on a DVD or flash drive). By the way, it’s an indispensable thing when you can’t run your regular Windows from your hard drive. You can find out where to download, how to create such a LiveCD, and how to use it from this article -.
3. you can try to use online versions of antiviruses (they do not require installation) - . Suitable in cases where it is impossible to install an antivirus, but you can download and run some files.
4. try using alternative anti-malware utilities (about them in the article below).

Check for embedded adware

Perhaps the most popular lately are viruses that are built into the browser and begin to show advertising everywhere (even where it has never existed and does not exist). As a rule, the classic antivirus does not find anything either in the system itself as a whole, or in the browser itself (in particular). In order to get rid of this “good” you need to use a special one. utilities...

AdwCleaner

One of the best utilities to combat AdWare (adware). Allows you to quickly download an executable file (weighs less than 10 MB!) and run the scan. I note that the utility sees most embedded advertising in the browser, malicious scripts, add-ons, etc. After scanning and verification, your PC will reboot.

By the way, what’s also captivating is that to start scanning, you just need to press one “Scan” button (see example below).

If everything went well, a window should appear stating that the cleaning was successfully completed and all detected threats were neutralized (example in the screenshot below).

Important!

By the way, AdwCleaner is now distributed as part of the package, which is also a very high-quality tool for combating such a number of viruses.

IObit Malware Fighter

This utility differs from the previous one in that it can not only scan, but also protect the computer in real time (in parallel with your antivirus). Helps to recognize many types of threats in a timely manner and protect the browser from changes by adware. I would also note a nice and friendly interface, aimed at novice users (for protection and verification, just click a few times).

Peculiarities:

1. scanning Windows for various malware (which ordinary antiviruses do not see);
2. possibility of real-time protection;
3. control over the browser start page, its add-ons, add-ons, etc.;
4. can work in parallel with classic antivirus;
5. Windows compatibility: 7/8/8.1/10 (32/64 bits);
6. completely in Russian, there is a free version of the program.

Protection against Trojans and malicious add-ons

I couldn’t help but single out into a separate “caste” of virus programs those that specialize in stealing personal data: passwords, logins, payment card data, take pictures of you with a web camera, record all your keyboard presses, etc. In general, these are not exactly “classical viruses”, and as a rule they behave very “quietly” so as not to give themselves away in any way (like spies, or the famous Trojan horse (hence the name)).

But when they receive the information they need, they immediately forward it to their developer. So, such “things” are much more dangerous than harmless advertising banners...

And, unfortunately, they are very difficult to identify. Ordinary antiviruses do not “see” anything, specialized software helps, but also not always...

AVZ

Multifunctional antivirus utility that does not require installation. It will help you quickly scan your system and remove: SpyWare, AdWare, Dialer (Trojan.Dialer), Trojan programs and other goodies. I will add that it also has several useful “things” in its arsenal: system recovery, unlocking entry into the system registry (viruses often block this), searching and eliminating vulnerabilities.

The screenshot below shows the necessary steps to check the Windows system disk for viruses and other malware.

AVZ - scan your computer for viruses (clickable)

As for eliminating vulnerabilities: go to the file menu and open the “Troubleshooting Wizard”, as shown in the screenshot below.

In my case, for example, autorun from connected media (CDs, for example) was allowed. In some cases, if the inserted media is infected and it will automatically start -> the PC/Windows will be infected.

It is advisable to mark all problems found and click the “Fix marked problems” button.

In general, the AVZ utility has dozens of functions and capabilities (it’s simply impossible to consider them in one article). I recommend that you definitely have it on your emergency disk (in case...).

SpyHunter

SpyHunter main window

SpyHunter (if in Russian: "Spy Hunter") - the main direction of the utility: combating spyware (Trojans, rootkins, worms, the utility also copes with many classic viruses, advertising toolbars, banners).

Peculiarities:

1. does not conflict with classic antivirus;
2. real-time protection (simultaneous operation with your regular antivirus is possible);
3. regular updates;
4. all changes (deletion, “treatment”, etc.) can be canceled if the program does something unnecessary;
5. user-friendly interface in minimalist style;
6. Russian language support, works in all new OS Windows 8.1/10 (32/64 bits).

Spyware Terminator

A free utility to protect your computer from Trojans and spyware in real time. I note that the application also copes well with other types of malware: advertising add-ons, worms, classic viruses, etc.

Peculiarities:

1. the ability to monitor file activity and the Internet in real time;
2. three scanning modes: full, fast and selective;
3. The utility has a built-in Clam AntiVirus antivirus (and a database of 40,000 different viruses, worms, etc.);
4. regular database updates via the Internet;
5. specialist. Web Security Guard database (when activated, your Internet becomes much safer!);
6. the ability to work simultaneously with a conventional antivirus;
7. Supported by all modern OS (Windows 8/10).

All the best and less viruses!

Hello everyone, dear readers! Obviously, since you got here, you have problems with your computer. Don't forget that viruses are a serious problem that can lead to dire consequences. In the best case, it will cost you to clean the computer with an antivirus, and in the worst case, you need to reinstall the operating system, take the computer for repairs and pay little money. And who needs it? That's right - no one. Therefore, in this article I will tell you how to check your computer for viruses.

And so, dear friends, how can you protect yourself from negative consequences? There are several ways to identify unwanted software so that they can be eliminated in a timely manner; we will consider the most effective ones.

First method

Detection of malware, without the use of any heavy installations, registrations, key entry and other red tape.
Ask how to do this, is it even possible? Yes, dear comrades, online research into dangers is possible! As Sherlock Holmes liked to say - elementary! This opportunity is provided to us by the company esetnod32.

To detect danger, you just need to follow this link - https://www.esetnod32.ru/home/products/online-scanner/. And so you go to the site and see this picture.

There is nothing complicated about this, click on the “Launch” button, enter your email address, by the way, you do not need to make any confirmations or go into the mailbox. They entered the e-mail, after which a small utility is downloaded, which will not take up much space, about 6 megabytes, this means that the download will be a breeze, 10 seconds and you’re done.

Installation also takes no more time; in fact, you just need to agree to the user agreement. Hooray! The research has begun, after which the utility will remove the malware, in general, heaven, not life! And most importantly it's free! It is worth clarifying that such services are provided by many well-known companies involved in computer security.

Second method

But what about people who are terrified of downloading something? Very simple friends! You can check without even going online. Yes, dear visitors, this happens! Now it is quite possible to detect malware without an antivirus.

You’re probably quite surprised, but there’s nothing complicated about it. To make this procedure a reality, you’ll need to click the “Start” button in the lower left corner and enter the following query in the search bar: “Windows Defender.”

Next, open the application itself, select what type of scan we need, full, quick or special. Of course, it’s better to do a full scan to make sure that all systems of your “iron horse” are safe, then click “Check Now.”

Actually, that's all! We enjoy the check, after which the Defender, if a danger is detected, will report it, and you will be able to eliminate them.

Third method

Detecting malware using a special utility. This method is of higher quality, since it is specially developed software that protects your computer. Let's look at proven software that is extremely popular among users.

And so ladies and gentlemen, we present to your attention the Kaspersky Lab antivirus! This is a truly good service developed by domestic developers. So how can you use it? Let's be honest, this method is more difficult than the first two, but it cannot be said that it is difficult, everyone can use it.

This is done as follows. Go here - http://www.kaspersky.ru/free-trials/anti-virus. Click “download”, I’ll tell you right away that the download will not be so fast.

Since the software volume is approximately 170 MB, you will have to wait a little, you can brew tea at this time. Have you downloaded it?

We launch the installation, which is quite simple and intuitive, but it lasts about 5 minutes, just as you can drink some brewed tea. And now, finally, the utility is installed and launched. Kaspersky will “ask” you to enter the activation key, but this option is not suitable for us, because it costs money.

But the developers allow us to use the trial version for 30 days, which we will do. Click on “Activate trial version”, the link is written in large font and highlighted, it’s impossible not to notice it. Now the utility is ready to go! Next, click on the “Run scan” button and launch it.

The procedure will take quite a long time, but it will really thoroughly check the entire system and eliminate its errors. In our opinion, this is the most optimal option for detecting malicious utilities.

Because Kaspersky really provides good services and, no less important, for most users it provides a free option to use, which is in demand.

Fourth method

Identify hazards using licensed software. Finally, we have reached the highest quality option. Because identifying threats using this method guarantees 100 percent security of your computer. The previous option is, of course, good, but it works on a trial version, and the activated system provides the user with a full list of capabilities.

This means that the full range of protection will work to the maximum, not allowing a single virus to pass through, thereby ensuring high computer security, thanks to which it will serve you for many years to come.

I’m almost sure that you are interested in this option, aren’t you? So how can you get such a high quality service? Nothing complicated. Let's look at the whole process using the well-known Dr.Web software. This is another Russian security software developer. Yes - yes, don't be surprised! The best security software was developed in Russia and is in demand all over the world.

To use this option, you need to go to the nearest electronics store and purchase a utility with a license, which is located in the box with the disk and is often protected by a special coating. You need to perform the installation using the disk, erase the protective coating and enter the key that activates the software.

The license validity period varies, in most cases it is one year, and then you need to buy a new key and renew the license. Or you don’t have to go anywhere, but buy the necessary software on the company’s official website (http://www.drweb.ru/). You will also be given a key in your personal account, which you will enter during installation.

After activation, you can search for threats with a clear conscience using a utility that will accurately identify all vulnerabilities and destroy them. Using an activated system is the surest option to find threats that will definitely protect your PC from viruses.

Yes, it costs about money (1,500 rubles), but you get continuous security for a long time. Plus, after the license expires, you can buy a new one on the company’s official website.

Thank you very much dear readers! I hope my article will help you secure your computer and identify any vulnerabilities found!

Send a suspicious file

This is far from the only antivirus program presented on the modern software market. There is a large selection of programs of varying quality and pricing. Analyzing the pros and cons of the presented applications in order to choose the best option is not an easy task even for an experienced user. Our virus scanning and removal program occupies a special place among them for several reasons:

• Constant and non-stop monitoring, detection and elimination of virus threats on the hard drive and external media. Checking your computer for viruses is a simple and quick process. Our team has used all the resources and developments of in-house programmers, as well as the best ideas of global experts in recent years. Such a union guarantees success.

Despite the fact that online antivirus services advertise themselves as tools without the need to download and install, this is not entirely true. One way or another, the user will have to organize access to the files.

This means you need to install some minimal software on your machine, without which you cannot perform the check. They are the ones who contact the anti-virus database of their own website. Since this operation is performed online, it is conditionally classified as an online check.

How to check for malicious content

The installation and verification algorithm is not particularly unique and for everyone consists of the following steps:

• downloading to your home computer the minimum necessary program files needed to communicate with the current database during the scan;
• installation (installation) of the program;
• computer check;
• results report.

The most famous antivirus components for online scanning

Kaspersky Security Scan

According to the ratings, for a long time Kaspersky Anti-Virus was in the lead in terms of quality of work. Easy to use and accessible. To check with the proposed free utility called Kaspersky Security Scan, you must first download it from the official website http://www.kaspersky.ru/ by following the link to the “Free Utilities” tab. A screen will open with a complete list of all free offers from Kaspersky Lab.

When you click on the Kaspersky Security Scan tab, you will be redirected to the download page.

After saving the required file (be sure to remember the folder in which the utility was downloaded), start the installation by “clicking” on the file.

Perform a full installation if you are not confident in your knowledge of the settings.

You can refuse to install the Yandex browser, which you will be asked to do in the next dialog box.

Select a check, it is indicated by arrow 1 in the image.

It will take some time to download the program, about 10 minutes. And then you can start with the check (arrow 2), in each of the subsequent windows by selecting the button corresponding to the task.

The scan report will be presented in the form of a board indicating the number of objects scanned, as well as the number and description of detected threats.

If malicious files were found, you should click “Search for a solution” and follow the instructions depending on the nature of the detected threats. The fact that the utility itself does not destroy programs that it considers malicious, but only points to them, will allow you to manually sort and save the necessary information.

Benefits of Kaspersky Security Scan:

• it is important that the utility does not conflict with programs from other manufacturers that are already running on the machine being tested;
• This is a Russian-language program, so it is easy to understand for users of the ru zone.

The closest brother of Kaspersky antivirus, which claims to be the leader in the rating, is BitDefender QuickScan (working link http://quickscan.bitdefender.com/). Abroad, it is considered the best online virus detection assistant. To install it, you need to click on the “Scan now” button on the official website of this antivirus service.

With your consent, a special extension will be installed on your computer for the browser in which you are working. This process takes much less time than installing Kaspersky, and further verification is much shorter. This is because BitDefender QuickScan does not analyze the entire computer system in detail. Only currently active threats.

According to user reviews, the program may conflict with existing antivirus programs on the computer or indicate problems in their operation. This utility can suit those who are well acquainted with the English language in order to understand additional features, tips, and recommendations.

A longtime friend and assistant of computer scientists - NOD32 antivirus

Another “antivirus” with a Russian-language interface is the good old NOD32. Or rather, a scanner from ESET. To download from the main page of the company’s portal (https://www.esetnod32.ru/), you must click on the “Online scanner” link at the bottom of the screen, as indicated by the arrow in the picture.

You can start downloading after entering your email. Despite the site's instructions that registration is not required, you will have to enter your email address, otherwise you will not be able to proceed further.

Virus scanning is launched by Internet Explorer without additional installation, but for others the service will offer to download and install Smart Installer.

Scanning a computer is not instantaneous; it may take time; its progress and results can be monitored in the active program window.

The advantages of NOD32 include the use of heuristic analysis. This means that using the available data from previous scans, the program can calculate previously unknown viruses by analogy with those that have already been identified. Found problematic files will not be deleted if you clear the checkbox from the “Remove detected threats” button during setup.

Panda ActiveScan and HouseCall

Without implementation on the computer, the antivirus program Panda ActiveScan (http://www.pandasecurity.com/activescan/index/) performs a cloud scan in Internet Explorer (only in it), which allows you to get rid of viruses without installing a full-fledged product.

HouseCall offers free content analysis and detection of spyware and viruses.

After accepting the license agreement, which, by the way, is in English, the ScanNow button will become available and you can start scanning the contents of your computer. The setting offers the choice of either a full scan or a quick analysis of the main sectors. HouseCall allows you to treat and remove detected viruses from the computer being scanned.

The program is “delicate”: it does not leave changes on the computer, which is an additional advantage.

Fans of popular Microsoft software can use its product: Safety Scanner (http://www.microsoft.com/security/scanner/ru-ru/), designed for a one-time computer scan. The program is valid for 10 days, after which you will have to download the updated version.

How to check files and websites for viruses online

It's easy to check individual files using services like Dr. Offers. Web or VirusTotal. To do this, upload the file that arouses your suspicions to the site and follow the instructions. This is convenient if you need to analyze a small amount of information.

Online scanning of suspicious files and sites for viruses using Dr.Web

The healing utility from Dr.Web is very popular. With its help, you can scan all information on your computer for viruses and malware. Individual files, as well as entire sites, are checked online, which can be done by following the link http://online.drweb.com. Enter the path to the file on your computer, or enter the URL, click on check - and the service will give you a report.

As a result, the service will provide you with a report where, in addition to information about the viruses found, you can find out almost all the statistics of the file.

To check a site for viruses, you first need to go to the appropriate tab, enter the portal address and start scanning.

The site is scanned a little longer than the file, and eventually you will be presented with a scan report. The “Clean site” message indicates that the site is clean and there are no threats.

The antivirus service VirusTotal.com presents VirusTotal Scanner, a program that requires installation on your computer.

The first thing that distributors of the boxed solution call is the ability to check without additional file transfer to the network. Simply enter the path to the file in the program window on your computer. The form of the report is similar to that on the VirusTotal website.

http://rsload.net/soft/security/11963-virustotalscanner.html) is suitable for operating systems Windows XP, 2003, Vista, 7, 8.x, 10 (32/64-bit). You can find and download the program on various resources.

As practice shows, using one, even a very clear and understandable anti-virus program, is, to say the least, not effective. According to reviews from network users, the best solution is to have an “antivirus” installed for permanent use on your computer, and be sure to update it regularly. Plus, periodically, especially if suspicions arise, check your unit additionally using the scanners and utilities described above.

It is important to remember that when choosing anti-virus services, you should contact only trusted sites, preferably directly to the Internet representatives of anti-virus program developers. Each of them has their own official websites, from where it is easy to download the necessary information or program. Manufacturers of “free” anti-virus software update their databases in a timely manner, keeping them up to date, and sometimes have a fairly wide range of free or shareware services.
