Hi I just ran a Malwarebytes scan like I do every week and it found Vilsel Trojan on 4 files.It quarantined them after i restarted machine.My last scan was on th weekend for Malwarebytes I think.My question is why did Bitdefender not pick this up ,i am not complaining about the software because it is very good just wondering why it did not see the trojan? Thks
