As such I'm blaming a virus but I've ran MSE's scan plus MalwareBytes Anti Malware's (as I always do when I go to the PC) and due to this situation I even did Panda's Active Scan 2.0 online and yet I have 0 threats or infected files in any of those three but I find no other explanation
BTW I'm using Win7 Ultimate 32 and besides the tools I've said I also use ZoneAlarm's Free Firewall.
Please help, Thanks
