Online website virus scanner Dr Web

This service is intended for scanning links for safety. It works in the following way:

  1. The user adds a link to a suspicious website into a text field,
  2. Dr Web scans the attached files on that html page,
  3. After examining the site code the service presents a report with the number of checked, safe and infected pages.

Usually a virus threat of online resources is hidden in its javascript files. If the scripts are contained on the database of malicious sites or the site redirects to another resource Dr Web Online will notify you.

Among the set of tools only a web anti-virus shell is available which isn't very convenient. It would be better if Dr Web Online got, let's say, an Android app for online validation or an online malware cleaner extension. Right now the online version of the virus scanner isn't suitable for full use on a phone.

Tip of the day. If you need a free and reliable virus scanner to check your computer (or your memory card/usb stick) I suggest you downloading Dr. Web CureIt curing utility. The program uses the actual database of Dr. Web desktop version. Its features contain everything you need and there is no need to download additional modules.

On the other hand, according to the creators, the online virus scanner successfully copes with trojans, malware, the latest viruses, worms and phishing threats.

The user can select the files on a computer disk for scanning, specify the region of memory and etc. Moreover you don't need to have the administrator rights to run the online scanning.

At the end of the search ESET Online Scanner suggests removing the viruses it has found and placing the infected files in quarantine.

Thus, searching for viruses via the web virus scanner ESET Online Scanner makes sense:

  1. if you want to scan someone else's computer or phone,
  2. check the flash drive for malicious files online but you don't have the rights to install applications.

Kaspersky Online Scanner (VirusDesk)

Malware online scanner from the makers of Kaspersky Antivirus. It scans files and links on the Internet and doesn't require an installation of additional modules.

If after the scanning a virus was detected VirusDesk reports: the file is infected or potentially dangerous.

Important! In contrast to usual virus scanners software with this one you can only scan a file for viruses, but the file won't be put in quarantine or automatically deleted. It can be done only manually.

Kaspersky Online Scanner is also suitable for an urgent scanning of a phone for viruses. You can upload files with the size no bigger than 50 MB. The batch mode isn't supported which is inconvenient if we're talking about a massive infection of files. The online scanner for Android doesn't remove viruses so the users should do it themselves.

The main feature of VirSCAN online virus scanner is an extensive database of regularly updated scanners: kaspersky, avg, drweb, symantec and others. In addition to this, VirSCAN checks the MD5 and SHA1 hashes through its databases.

As the authors of this web virus scanner warn sometimes a false alarm can be triggered, which isn't surprising when taking into account such an impressive list of antivirus bases. But as experience shows it's better to be safe and put suspicious files in quarantine.

The cons of the online virus scanning are pretty obvious:

  • a slow speed
  • the lack of any settings
