How to scan your computer for viruses online. 10 ways

The question of how to check your computer for viruses online is very popular among novice users. Before suggesting methods of checking, I recommend reading the following information about online virus checking: The main thing to know is that you cannot perform a full scan of all files on your computer somewhere on the Internet, because then you would need to download the entire contents of your PC or laptop to this site. But you can:

  • Check for viruses individual programs and other files completely online by downloading them to special services.
  • Download special anti-virus utilities that, although they are called “online scanners”, but they work specifically on your computer, and from the Internet use the anti-virus database to check (which can also be downloaded to your computer). As a rule, they do not conflict with already installed antiviruses.

In this instruction in detail about various methods of online checking for viruses of a computer with Windows 10, 8.1 and Windows 7 or individual programs and other files. I note that often the cause of various problems with the computer or the Internet are not viruses, and malicious programs that conventional anti-viruses “do not see”. In this case, I recommend trying special malware removal tools.

How to check for viruses on your computer or a single file online

Unfortunately it is not possible to scan your computer for viruses with just one site open in the browser. The thing is that for security reasons web-services do not have access to local files and programs on your PC.

But there are cloud antiviruses that can scan your system without a full installation and registration. To use one of them, just download a small client and run it. You will then be able to scan your computer as a whole or select partitions for partial scanning. In the process the program will download the data it needs from the cloud. If the service detects viruses, it will offer to remove them.

If you want to check your computer with cloud antivirus, try these services. All of them are products of well-known companies and work in a similar way. according to the scheme described above. So you can choose any of them.

ESET’s Free Online Scanner

A tool from one of the most popular antiviruses. Works without installing, but won’t start scanning until it downloads its signature database. Allows you to choose between full, quick, or selective scans. Found malicious files can be quarantined or automatically deleted.

Kaspersky Virus Removal Tool

Unlike the previous antivirus, this one comes with a built-in database, so, strictly speaking, it does not work online. You choose which locations to scan. RAM, autorun, bootloader and Windows partition available. and click “Start Scanning”.

Dr.Web CureIt!

Analogue to Kaspersky Virus Removal Tool by Dr.Web, perhaps even more popular. Also disposable. as it becomes obsolete, you have to re-download the program.

Norton Power Eraser

The program promises to eliminate “deeply embedded rogue programs” and uses “aggressive scanning techniques”. What this really means is that Norton Power Eraser compares the files it finds to a list of trusted and malicious applications in the cloud. If the program is not sure if the file is dangerous, it will offer to send it to Symantec’s servers for a more thorough check.

F-Secure’s Online Scanner

Fastest scanner of all. No settings, so you don’t choose which files to scan. Only the Windows system folder is scanned.

Panda Cloud Cleaner

Is the only scanner listed that requires installation. Yet it weighs only about 30 MB. Suspicious files found by the program are automatically sent to the cloud for scanning. In addition to removing malicious applications, it can also clean the history and temporary files of the browser.

Trend Micro HouseCall

It offers a quick, full or custom scan (only in folders you specify). Detects malware and spyware by signature database. In addition to the Windows version, Trend Micro has a Mac version as well as a tool to scan your home network for vulnerabilities.

It’s highly likely that you’ve already encountered computer viruses. If not, you are very lucky. However, if you use Windows you should always be on the lookout.

At the beginning it should be said that free online antiviruses are not a replacement for standard antiviruses, but they can be very useful in an extreme case, for example, when some unknown PC behaves strangely or a little bit jammed.

Here are the most reliable and free tools to find and remove viruses, plus a few services to analyze individual files.

Such antiviruses can scan your entire system and analyze and delete files. However, we would like to repeat that such services do not replace traditional antiviruses, as they do not provide real-time protection.

Also note that not all antiviruses run in your browser. For example, in the case of Panda Cloud Cleaner, you will have to download the application to your computer.

Kaspersky Virusdesk. An online service to check files and links for viruses and to report false positives and new viruses.

Kaspersky Anti-Virus databases and file reputation data from Kaspersky Security Network are used for scanning. Kaspersky VirusDesk reports the known threats found in the file and shows the detailed information about the file. File healing is not provided.

checking, your, computer, viruses, installing

Results of file scan with Kaspersky VirusDesk may differ from results of Kaspersky Lab antivirus programs due to different settings.

Kaspersky VirusDesk checks files and archives up to 50 MB in size. If you have several files, add them to the archive with the password virus or infected. If you want to check a file larger than 50 MB, we recommend that you use Kaspersky Whitelist to check the checksum of the file.

Panda Cloud Cleaner replaces other online antivirus Panda ActiveScan and has been enriched with new functions. For example, you can terminate unnecessary processes before you start scanning, which increases the chances of finding malicious files hidden behind real processes.

This antivirus is very easy to use. After scanning is complete, you can choose malicious files to delete. However, searching for malware can be time consuming, so if you are in a hurry, you may want to consider alternatives.

ESET Online Scanner, one of the most “meticulous” free online antiviruses. Inteace is simple and shouldn’t be a problem to use. You can choose between full/quick and random scans. Plus, you can choose whether to quarantine or delete malicious files. Quarantine is useful in case of false alarms.

You did not misunderstand. You can search for malicious files right from within Google Chrome. Since it’s a very popular browser, there’s a good chance you have it installed.

To run the scanner, copy the following line into the address field chrome://settings/cleanup (won’t work in other browsers). Once the page loads, select Find and wait for the process to complete.

F-Secure Online Scanner

F-Secure Online Scanner is the fastest antivirus of its kind. Able to detect most malware and does not require installation.

The functionality of this antivirus is the easiest. Full system scan only available. However, given the speed, there should be no problems.

Analyzers or individual scanners, unlike online antiviruses, do not scan the entire system, but, as the name implies, are designed to analyze individual files before they are used in the system, instead of quarantining them upon detection.

over, by sending your files for analysis, you help update the signature and algorithm database of such services.

Again, individual file analyzers also do not exempt you from using traditional anti-virus packages on your device.

VirScan allows you to download files of up to 20 MB for analysis based on a huge database of file signatures collected from all over the world from other antivirus programs.

You can download a ZIP or RAR archive, but not more than 20 files.

VirusTotal allows you to analyze a file (or hash of a file), URL, IP address or domain, and has the richest features and largest database of malicious files and signatures.

As with the previous analyzer, VirusTotal collects file descriptions from all over the Internet. Additionally, you can do analysis via email. You send a file directly to VirusTotal (up to 256 MB) and wait for an answer regarding the status of the file.

MetaDefender. Collects signatures from 30 anti-viruses. In general, the analysis process is similar to the previous services. Available for file, IP, URL or domain scanning, as well as CVE.

Which online antivirus is the best?

All services have one drawback, related to the inability to provide real-time scanning and protection, which is very important in today’s world, where new threats appear every day.

But if you are strapped for cash, as you may have seen, there are many free and worthy alternatives.

ESET Online Scanner, a one time antivirus. Its peculiarity is that it works without installation. Unfortunately, it requires a valid email address to launch it, to which a download link will be sent.

Norton Security Scan. Another one time antivirus. Download here. Inteace is English-language, but simple.

Checks hard drives very quickly. Requires the internet connection, just like Eset Online Scanner.

In general, it is better not to use it, because viruses common in Russia get into its database a bit late. The newest vinlockers (ransomware banners) are unlikely to detect.

VirusTotal

All previous variants had one common disadvantage. the need to download the installer. In this case, you can scan your computer for viruses online without installing any software.

VirusTotal is a service from Google that can check any files on your PC. It can also scan sites for malicious utilities. Using this service is very easy:

Wait for the scan to run, then see the report.

VirusTotal file scanner

You’ve downloaded a cool new app, but want to make sure it’s clean before you run it. You can check it with any anti-virus you have installed, but a second opinion won’t hurt. So use VirusTotal.

Additional programs for computer scanning

Other anti-virus companies also offer similar solutions, as does ESET. The most effective among them (according to VirusTotal) are:

Their main advantage is that they are absolutely free, but they scan with the “latest” signature databases. That is check with their help will be as effective as with installed antivirus program.

Dr.WEB Cure It

  • Total protection mode. If you switch it on, all background processes stop and you won’t be able to use your PC until the end of scanning (the desktop will simply be blocked). This may be useful when the computer is connected to the local network and the server is “infected” at this moment.
  • RAM-only scan mode. Takes less than a minute to execute. but still allows to detect all viruses. An excellent variant for fast computer diagnostics for infection.

By the way, unlike other similar utilities, Cure It is downloaded with a full update package. In other words, the program can be run on computers without an internet connection. Eset Scanner Online, for example, requires Internet access for scanning.

Kaspersky Virus Removal Tool

You can download it from the official web-site https://www.kaspersky.com/. Similarly to Cure It, the downloader has all the signature updates integrated, so you can use it even on computers without an internet connection. All you need to do is run the downloaded program and click “Start Scan”. There are a minimum of additional settings here:

  • You can specify the folders where the scan will be performed;
  • Scanning mode can be set (fast, deep analysis).

The main advantage of Kaspersky Virus Removal Tool is that databases are updated up to 4 times a day. Decrypting files infected by viruses such as Petya, WannaCry (belonging to Virus-Encoder group) is supported. And for advanced users, there is also a special version of Kaspersky Virus Removal Tool for bootable media. It can be used to restore the computer if Windows cannot boot at all after an infection.

AdwCleaner

  • scheduled scanning is supported;
  • can “check” plug-ins for installed browsers;
  • Advanced uninstallation of potentially dangerous software installed on your computer can be performed right from the program window.

Among the disadvantages, we can mention only infrequent database updates compared to Kaspersky, ESET, Cure It. Also, AdwCleaner has no “Quarantine” section. In other words detected viruses and infected files can be either left or deleted completely. But you can’t put it in a temporary repository.

This utility is more suitable for advanced users, as it has a wide range of options. You can scan only specific groups of viruses, there is a “Quarantine” (temporary storage for suspicious files) and scanning of the whole local network is supported. But most importantly. there is an “eurestic” scan function. That is the utility launches certain programs in background, gives chaotic commands to it and analyzes its “behavior. In such a way potentially unsafe programs which conduct unauthorized data gathering about user are detected.

To start scanning you only need to open the program and click “Start. By default only files from boot sector and Windows folder are scanned. If desired, the user can select disks or folders that will also be checked.

Virustotal

Google’s service for checking your computer online only, without any installation. Able to detect, cure and remove viruses of any complexity, thanks to extensive databases.

  • Go here: https://www.Virustotal.com/gui/.

Unfortunately, there is no full system-wide scan.
