The threat situation is relatively quiet at the moment, so that we would like to take this opportunity to introduce you to a very useful service called "VirusTotal" at http://www.virustotal.com.
VirusTotal offers a free-of-charge analysing service for any type of suspicious file. Upload any such file to the website for analysis. It will then be checked by some 40 virus scanners. This service provides for fast detection of viruses, worms, Trojans and other such malware.
Please note: VirusTotal is no substitute for an anti virus program, which should be installed on your computer. This service only checks individual files on request, and does not scan your whole computer. VirusTotal does not offer any permanent protection of your computer either.
