I installed CA ISS a few days ago. Last night I downloaded PCPitstop Optimizer 3. Using Revo Pro Uninstaller, I uninstalled PCPitstop. Now my CA ISS doesn't work. Their tech support couldn't help much. I spent 6 hrs on the phone with them today. Got nowhere. I found more clues to the solution in 5 minutes (googling). My question - please rank the top or top 5 Internet Security packages (SpyZooka, etc) and system optimization packages (RegZooka, etc.). Thanks!
