5 days ago I was conned Into downloading something turned out to be some sort of Malicious Trojan software.
From then on, every few minutes a Norton pop-up would say "Norton Blocked an Attack by: System Infected: Trojan.dropper Activity 3." it would suggest Norton Power Eraser but all that is doing now is deleting random games from my computer and is now trying (and failing) to delete my entire Steam file from program files.
I know it's not working because despite doing nothing but deleting my entire Steam library, my C: drive is slowly filling up. A full scan doesn't show anything wrong either; A Full Scan, doesn't detect ANYTHING, that has happened, Security history however, has, it even shows the IP of the other Computer that's attacking as well as the suspected websites.
