Your right about that, but this site is good for quick files (like keygens) which I do not trust at ALL!!!!!! And I don't want to just rely on just one antivirus program. But I feal a lot better about this:
ATTENTION: VirusTotal is a free service offered by Hispasec Sistemas. There are no guarantees about the availability and continuity of this service. Although the detection rate afforded by the use of multiple antivirus engines is far superior to that offered by just one product, these results DO NOT guarantee the harmlessness of a file. Currently, there is not any solution that offers a 100% effectiveness rate for detecting viruses and malware.
