Hi! At first it seemed like Malwarebytes' Anti-Malware had worked to get rid of antispyware soft. After following the download directions for it, and running the scan as suggested, the incessant pop-ups were gone, but I looked in my notification area icons, and it was still there. Well, different super random letters.exe, but with the same Antispyware Soft phrase under it, and a weird icon (barely an icon). Like so...
So it seems gone, I followed the instructions you gave for getting chrome and IE to work. But I know it's still there and I'm scared of it (sounds paranoid).
I also updated Norton, and it says my 360 is version 4.1.0.32
Help and thanks!
