You don't remember what you had uninstalled?
Sounds like you had uninstalled more than one program. Yes?
1.Turn Zone Alarm back on.
2. Go to Safe Mode and run your Zone Alarm. see if it catches anything. I think your computer is infected.
3. After that, do a system restore while still in safe mode.
How to go to Safe Mode....
Turn off computer > turn computer back on > immediately and repeatedly tap the F8 button until you see a black and white screen. That is your safe mode > use the arrow key and select Safe Mode.
