So one of my computers running Windows 7 got infected by a trojan I think. It keeps popping up some "Anti Spy Safeguard" thing that i never installed, and I can't get rid of it! It wont let me have internet access saying that it is "unsafe" Any ideas for removing it? ETA: this particular machine has AVG on it, and it still somehow got through Wanna kill these ads? We can help!
