3. Kaspersky Scan Now!

Kaspersky Online Scan service doesn't allow neither removal nor healing of detected infections, my suggestion is that you use some other scanner to eliminate present malware. However, I myself use Kasperksy to verify the clean state of the system. Two scans are always better than one, don't you agree? ;) And Kaspersky is important because it is the only PC security scanner developed by Russian programmers, so its algorithms are very much unique.

“Panda” scanner will save us from popular viruses. Another good thing is that it scans our e-mail too. But on the other hand, this scanner doesn’t perfectly detect Trojans and backdoors.

9. Trend Micro Housecall!

If you are being attacked by popular viruses, than you need to scan your PC with Trend Micro Housecall. This scanner easily finds and kills popular viruses. But on the other hand, rare viruses usually aren't found by “Housecall” and Trojan horses escape too. “Rootkits” has even bigger chance to hide from this program.

The following online scanners were tested
F-Secure, Trend Micro, Symantec, Panda, BitDefender and Windows Defender scanners were tested.

Which one is the best?
No virus will survive against BitDefender. Program perfectly kills viruses, Trojan horses and backdoor programs. Spyware and rootkits has a better chance to hide from BitDefender, that’s why I also recommend scanning your PC with an anti-spyware.You should use Internet Explorer, because other browsers are not supported. If you are using Firefox 19, you can install an extension, which is called “IE tab”. It will make BitDefender think, that you are using IE.

13. Dr.Web Online Scanner

DrWeb is another PC security product from Russia. The desktop version of DrWeb is very popular in Russia and CIS countries - and there must be serious reasons for that. DrWeb offers to scan single files - the webpage is as simple as possible, there's nothing on it except the "browse" button to specify the path to the target file.
