Huge problem after new update

Avast Free Antivirus / Premium Security
1

Currently running in my Kaspersky rescue disk browser atm. I downloaded the new Avast program update to the one that just came out and Now I noticed that my behavior shield is disabled and my boot time is very slow I can’t even uninstall it to reinstall it. So basiclly everytime I reboot my computer it locks up within minutes and my avast behavior shield is disabled. I can’t even surf the internet, etc. So I gotta use my rescue disk just to get here. Please help!

Im currently running:
Windows XP SP3
1.72 GB of RAM
and I can’t get any info atm… since I can’t access it.

and for a update I was able to enable the behavior sheild but when I minimized it avast disapeared and my PC locked up and I can’t re-open it so right now Im gonna run my rescue disk just incase I got some trojan or something because I couldn’t open my emisoft and malwarebytes either because the PC locked up.

Try to run Safe Mode, and run a full scan of malwarebytes.

If this is not possible, download the tool TDSS killer and perform the scan. Give the scan results here.

So got into safe mode, Malwarebytes found nothing and then I uninstalled avast and rebooted and that solved my problem. Can’t believe I forgot about safe mode -_-
