ViolaSoft is a fake antivirus. It is very different from other rogues though, as it doesn't pose a threat to the Target computer. The program is rendered useless as ViolaSoft serves no purpose.
ViolaSoft is a member of the family of other fake AVs developed by MrNoobWarrior.
Appearance and performance
ViolaSoft appears to be very messy as well as to have awful grammar.
ViolaSoft is also extremely fragile and unstable when the program is either downloading fake updates or is being spammed by the user.
Since the program uses MD5 hashes to detect malware, it can't find anything and could be easily tricked to delete important system files with a simple modification of viruslist.txt.
