Antivirus Scans and False Positives

AntiVirus and AntiSpyware False Positives

Some false positive reports occasionally pop up in different antivirus products in conjunction with software. This is partially due to the compression and portablization techniques used but mostly due to a failure of some antivirus companies to properly test virus definition updates or using questionable heuristics detection method. If you encounter a false positive, please test the file in another antivirus product before reporting the issue to us in the forums to ensure that it's not an error in their software. Several companies make available online scanners for individual files, so you won't even have to install software (VirusTotal, MetaDefender, Jotti). Note that these online scanners use dozens of antivirus engines and will generally show false positives in a few of them. In particular, Antiy, Bkav, Jiangmin, Qihoo, and Trapmine seem to have frequent issues with false positives and can usually be ignored. You can also use ClamWin Portable or Emsisoft Portable to scan on the go. Thanks for your help.
