On one of my laptops (win xp pro, all updates) at startup Avast (IS latest version) fails to load fully (no icon in the sustem tray, though the process is shown as started in MSconfig), and is preventing other startup apps (Ghost, Dropbox, HP Print monitor etc) from starting as well. Outlook opens but I cannot open mails for reading. On shutdown the system hangs showing just the wallpaper.
If I uninstall AIS everything else works fine.
I have also deployed aswclear.exe mutiple times in safe mode. Whenever I reinstall it wors fine until a reboot when I get the same problems.
My other laptop, with pretty much the same setup, is fine.
Help!
