Computer hangs after installing new Avast Update

[Kaorichan2009]

That's basically it... I can't do much, it won't even load Avast. Nothing else loads, uninstalling fixes the problem completely! But reinstalling the program brings it back, thinking the old install corrupted.
Computer is a Windows Vista.

....Um. What I'm trying to ask is: DId the update do this to her computer... It seems theres enough evidence of such... and should I just go with another AV or wait till avast fixes this update?

I had 2 Windows 7 32bit machines hang on me today for unknown reasons.  In the end I restored the first (Dell Vostro desktop) to factory settings and am in the process of getting everything put back on.  I fired up my Toshiba laptop which hadn't been on in about 15 days and it also wouldn't do anything once it booted.  Coming up ZoneAlarm gave me a warning about avast which I thought was strange but I allowed it and once up this machine wouldn't do anything either.  The ZoneAlarm alert got me thinking so I hard powered off and uninstalled avast in safe mode and all is well. I will try reinstalling avast tomorrow and see what happens.

Forgot to mention... I also have a Windows 7 64bit machine that is running fine with avast.

I reinstalled avast on my Toshiba laptop and it seemed to go fine until just after the welcome to avast popup was seen and the system froze again.  I did another uninstall in safe mode and will continue troubleshooting later.

• What version of avast!?
• What version do you now have running?
• How did you update version?
• Is this a virus version update or a program update?

Was this after a windows update

This week, I ran into 3 computers running avast 1497, all were absolutely unusable. Removing avast in safe mode fixed the problem. Re-installing made the problem come back. Ended up installing AVG on those computers. What happened? a botched update? Corrupted update?
It also seems that those PC were also running trusteer. Maybe an incompatibility between trusteer and an avast update??

My XP SP3 desktop takes far longer to boot than it used to, the task manager shows Avast AV Free version as the reason, does Avast have any plans on speeding up their code? If not I'll find another AV.

That's a completely different situation. We're talking about absolutely unusable pc due to avast here, not a "little longer boot time"

Xp On my IBM T41 yesterday frozen on SVCHOST.EXE. 100%cpu usage on recent update on avast & Windows update and crippled my other desktop same problem Elonex prosenia 2000 same fault in windows xp. Even when uninstalled avast. Both were unuseable!!! stuck 100% CPU Usage. The Elonex later blue screened 0x0000007a fault maybe memory ram fault on this running mem test on this.

Only thing was recent windows update was installed on both. Threw both back in safe mode on system restore and reinstalled avast 8.01497 on the elonex. The T41 still stuck 100% CPU.
Re imaged the hard drive and had to re install windows xp & starting to re install all the windows updates.

Thank you for that data.. It may well come in useful

After no luck with 8.0.1497 I tried beta 2014 RC3 (build number 9.0.2005) and it's working fine on my Windows 7 32bit machines.

Do you have trusteer rapport installed?

[jvidal]

BTW, the Devs don't have anything to say about this (HUGE!) problem??

bye!

I do have Trustee Rapport on all three of my machines but the one running Windows 7 64 bit was unaffected.  The two machines running Windows 7 32 bit are now running avast 2014 RC3 with no problem and Trustee Rapport is on both of them.
