It is very likely that you have already encountered computer viruses. If not, then you are very lucky. However, if you are using Windows, you need to be always on the lookout.
At the outset, it should be said that free online antiviruses are not a replacement for standard antiviruses, but they can come in very handy as a last resort, for example, when some unknown PC behaves strangely or is a little junk.
Below are the most reliable and free tools for finding and removing viruses, plus several services for analyzing individual files.
The best online antivirus software.
Such antiviruses can scan the entire system, as well as analyze and delete files. However, we will repeat once again that such services do not replace traditional antiviruses, since they do not provide real-time protection.
Also note that not all antiviruses run in the browser. For example, in the case of Panda Cloud Cleaner, you have to download the application to your computer.
1. Kaspersky Virusdesk
Kaspersky Virusdesk is an online service for checking files and links for viruses and for reporting false positives and new viruses.Antivirus databases and data on the reputation of files from the Kaspersky Security Network are used for scanning. Kaspersky VirusDesk reports known threats found in the file and displays detailed information about it. File disinfection is not provided.
The result of scanning a file using Kaspersky VirusDesk may differ from the result of scanning by Kaspersky Lab anti-virus applications due to different settings.
Kaspersky VirusDesk scans 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 using Kaspersky Whitelist to check the file's reputation using the checksum.
2. Panda Cloud Cleaner
Panda Cloud Cleaner replaces the other online antivirus Panda ActiveScan and has been enriched with new features. For example, you can complete unnecessary processes before starting a scan, which increases the chances of detecting malicious files hidden behind real processes.
This antivirus is very easy to use. Once the scan is complete, you can select the malicious files to remove. However, searching for malware can be time-consuming and therefore, if you are in a hurry, you may need to consider alternatives.
3. ESET Online Scanner
ESET Online Scanner is one of the most meticulous free online antiviruses out there. The interface is simple enough, and you shouldn't have any problems using it. You can choose between full / fast and custom scan. Plus, you can choose whether to quarantine or delete malicious files. Submitting to quarantine comes in handy in the event that a false positive occurs.
4. Google Chrome
You heard right. You can run a search for malicious files directly from Google Chrome. Since this browser is very popular, chances are high that you also have this application installed.To launch the scanner, copy the following line chrome: // settings / cleanup into the address field (this will not work in other browsers). Once the page loads, select Find and wait for the process to complete.
5. F-Secure Online Scanner
F-Secure Online Scanner is the fastest of its kind. Knows how to find most malware and does not require installation.
The functionality of this antivirus is the simplest. Only a scan of the entire system is available. However, given the speed of work, there should be no problems.
Malicious file analyzers
Analyzers or individual scanners, unlike online antiviruses, do not scan the entire system, but, as the name suggests, are designed to analyze individual files before using them in the system, instead of quarantining them upon detection.In addition, by submitting your files for analysis, you help to update the base of signatures and algorithms of such services.
Again, individual file analyzers also do not exempt you from using traditional antivirus packages on your device.
1. VirScan
VirScan allows you to upload files up to 20 MB for analysis based on a huge database of file signatures collected from other antivirus programs around the world.
You can download a ZIP or RAR archive, but containing no more than 20 files.
2. VirusTotal
VirusTotal allows you to analyze a file (or hash of a file), URL, IP address or domain, and has the richest functionality and the largest database of malicious files and signatures.
As with the previous analyzer, VirusTotal collects file descriptions from all over the Internet. In addition, it is possible to do the analysis by email. You send a file directly to VirusTotal (up to 256 MB) and wait for a response regarding the status of this file.
3. MetaDefender
MetaDefender - collects signatures from 30 antiviruses. In general, the analysis process is similar to previous services. File, IP address, URL or domain scanning is available, as well as CVE.
The interface of the app is pretty simple.
What's the best online antivirus?
All services have one drawback associated with the inability to provide scanning and protection in real time, which is very important in the modern world, where new threats appear every day.
However, if you are on a budget, then, as you can see, there are many free and decent alternatives.
