The good and the bad about AV multi scanner services

Online AV multi scanners are used quite often these days. However, not every user is aware of these sites and what their possibilities and limits are. Using the public online multi scanner services can be useful, but the analysis results don’t allow straightforward conclusions.

One of the easiest ways to accumulate a minimum of the desired information is provided by using online AV multi scanners. There is an interesting concept behind that: when you found a suspicious file on your pc, you can easily upload it to the service and have an immediate result as the file itself will be scanned with various up to date virus scan engines. This principle has been around for years now and gives you some immediate insight into a suspicious file. And there are indeed several of these scan service sites around. The most popular possibly is VirusTotal but you have several other ones like Jotti, NoVirusThanks, Metascan or Virscan, to name only some of them.

This feature is handy if you don’t have an actual file but know the hash value of it.
