Recently I discovered two more website which offers FREE online virus scan service that checks uploaded files for malware using multiple antivirus engines. It is VirusChief and FilterBit. Previously I’ve already mentioned 4 such similar sites which is VirusTotal, Jotti’s Malware Scanner, VirSCAN, Virus.org Malware Scanner.

BEST Online Virus File Scanner
Since I already have 6 on the list, I thought it’d be great to make a comparison between these 6 websites to see which offers the best features. I will compare the number of antivirus engines used to scan an uploaded file, time taken to upload and scan, extra file upload methods, file information, upload progress meter and report page. I will also test the accuracy of the antivirus engines by scanning it with a detected version of Bifrost trojan.

All 6 online file scanner websites don’t require Java or ActiveX. From the test, VirusTotal is clearly the winner because it surpasses other websites in every part of the test! It is able to archive 100% detection rate for Bifrost trojan with 32 antivirus engine in the fastest time. VirSCAN easily taken the second place because of the features and also amount of antivirus engines. However, the only thing I don’t like about it is the slowness in uploading and scanning which I could live with it.

Jotti’s Malware Scanner with Virus.Org is a very very close one. I could not decide which would be better so I would say that it is a draw. Jotti archived 100% in detection rate, supports 10MB upload, and fast scanning time. It would be better than Virus.Org if it has report page.
