I had Avast! 4.8 latest updated, after uninstalling it and installing Avast! 5.0.418 and rebooting, all good but after the seconf reboot 'SeaMonkey.exe' couldn't be executed, I uninstalled SeaMonkey 2.0.2, but 'SeaMonkey.exe' remained but I couldn't delete it, I made a 'chkdsk' on all partitions, twice (one in Safe Mode), I downloaded Avast! 4 & 5 Cleaners, I used 4 Registry Cleaners (COMODO System Cleaner, CCleaner, ERUNT and Advanced System Care PRO), I even defragged C: to see if it was a NTFS issue but no, all ran OK but I still can't Install SeaMonkey 2.0.2. Files are copied to the disk but 'SeaMonkey.exe' is not created nor the SeaMonkey's user profile (%APPDATA%\Mozilla\Profile\xxxxxxxx.default).
Could this be my system or Avast! 5 glitch?
Thank you.
