Avast 5 - Computer Freezes up/Slow when start up?
« on: January 21, 2010, 01:32:23 AM »
I don't know if it's just me or after I downloaded/Updated Avast 4.8 to Avast 5.0 I seemed to have gotten slower on my computer and after i start up i seem to freeze after 5-10 minutes from the startup. Avast 5 is working fine and everything's good. When my computer freezes up i can move my mouse but everything else seem "frozen". I then manually restart the computer by Pressing the ON button.

Is it just me or is there something wrong?

-I'm new by the way, Name's Anar :P

It was an issue I had in beta. There are others with the same issue relating to problems with Cybermedia DVD loading their DVD drivers and things

If you can make a memory dump and talk to Igor or Vlk, they could look at it and try to fix what is causing it.



Most systems see some slowdown after the first couple reboots as you cache is rebuilding. But shouldn't freeze your pc.

my pc, also slows down when i try to install avast 5 pro. And the worst part is that i cant stop the shields , and i need to uninstall it. So the only way i can use avast 5 is with the free version and my pro key. Also i lost the internet connection. And i have done more than 8 boots and everything keeps the same, my pc not responding. Also i have created a record of my problems during setup, but nobody have answered my problem. So i will stick to v5 FREE, because is the only way i can use v5 of avast antivirus.

Well the thing is i already Downloaded Avast 5 Free Version, previously known as the Home Edition. But like after every start up my computer just freezes and nothing seems to work but my mouse moves fine. This only started happening AFTER avast 5 was Downloaded and Running. Also My computer seems a bit slow, but what can i do to fix this problem? UNinstall and then REinstall?

Try removing the Behaviour Shield (you can reconfigure Avast 5 from Add/Remove Programs).  Please tell us if that resolves the problem for you.

Same problem here. Then takes couple of reboots to get to the stage where i can uninstall (reboot) then install 4.8 (reboot).

Tried reinstalling again and it either doesn't finish the install (reboot). then freezes the PC or seems to install fine (reboot) then doesn't run at all.

All times i unstalled 4.8 first (reboot) and a couple of times ran the cleanup script after(reboot).

Just wondering if 4.8 still be updated for the foreseeable future and when serial runs out will new serials be accepted?

Same problem here. Installed new version yesterday and computer kept freezing when I was trying to configure settings.
Task Manager wouldn't work, Icons on desktop wouldn't work, and icons in tray wouldn't work. Only cursor was movable but nothing would click.
Couldn't even reset computer I had to switch it off.

After leaving it on all night (always do) this morning everything was frozen again, had to switch the computer off and on again to regain control.

Nothing about it showing in Event Viewer. I haven't installed anything else for weeks.

Still got another 6 months of subscription otherwise I'd uninstall it and get another AV.

It is indeed wierd as it happens on my XP Pro system regularly. 

I tried removing some shields to see if the system did not have enough RAM and it is still failing at first boot up in the morning.

I am only running File System, Web, IM, Network, Script shields and Process Virtualization

I think I will un-install avast! Pro and try avast! Free for a few days.

I will keep avast! as I know the problem will be fixed.

unfortunately I noticed the pc started to go slow while browsing (6 mega connection)...do not know why...but it does. It was a clean install of Avast 5...no problems with avast 4.8 home edition...so I have to go back to it.

will wait a little to go back to 5 if there is something avast perhaps might fix.
