installed 393 on top of 377 everything went fine. No problems now in XP sp2.
cheers
Installed 393 Pro over 377 Pro on Vista x32. No problems before, no new problems now.
What OS and language are your friends using?
Update
Just experienced the first random system freeze with version 5.0.393. This means the problems haven’t been completely rectified yet.
The freeze occurred whilst being away from the computer for half-an-hour. MBAM resident, Firefox and PCTFW were the only programs loaded. Memory usage was 380 from 2,440 (lower than under 4.8.1368!)
I hope this helps Alwil to rectify the random freeze problem with Avast 5 on Window$ XP Pro $P3 systems.
Avastfan1, you mean like a complete freeze, or just programs becoming flaky? If complete freeze, could you at least move the mouse cursor?
Hi Vlk,
It indeed warms my heart to received a personal response from Alwil! Thank you!
The mouse cursor can still be moved, however everything else is frozen. The Task Manager cannot be activated (with control, alt and delete) and nothing else responds. Not even the Start Menu.
Hope this helps and I look forward to your response!
Best wishes,
Avastfan1
OK, now it’s my turn to have trouble… 
I’ve run Avast Pro 4.x for many years with no problems at all.
Updated to 5.0.377 when it was released. No problems… Just installed over 4.8
Tried to install the new version 393 and then the problems started.
PC froze on startup - Avast icon spins two times and then PC freezes, even the mouse goes dead…
Uninstalled in safe mode and tried a new fresh install - same problems…
Reboot in safe mode and unticked the Behaviour Shield in Add/Remove programs.
PC starts just fine…
Tried one more time to activate the Behaviour Shield, and PC freezes after reboot.
Disabled the Behaviour Shield one more time, and everything is back to normal.
…so as a summary: With 377 everything runs just fine - Behaviour Shield included.
…with 393 I can’t get my computer to run with Behaviour Shield.
Windows XP Pro SP3
Win7/32 installede 5.0.393 on top of 5.0.377
