About VirusTotal
VirusTotal is a service that analyzes suspicious files and facilitates the quick detection of viruses, worms, trojans, and all kinds of malware detected by antivirus engines.
Specs:
•Free, independent service
•Use of multiple antivirus engines
•Real-time automatic updates of virus signatures
•Detailed results from each antivirus engine
•Real time global statistics
VirusTotal is used only to further scan the file in question to determine if other anti-malware scanners are defining the questionable file as malicious too. Very useful tool but does not assist the user in removing any actual infection.
In addition, VirusTotal does not include such noted anti-spyware scanners as Malwarebytes Anti-Malware, SuperAntiSpyware, TrojanHunter. These programs frequently find infections that the noted AVs miss. Thus VirusTotal can be misleading and instill a false sense of security.
And after some consideration, the feature will not be shipped with PowerTools. This is to limit the impact on the setup package (and our bandwidth costs). Instead, if user wishes to use the Anti-Malware, upon the first use it will download the files needed by the engine. A simple and elegant solution that should make everyone happy.
I feel the above is a very good decision.
