Hello everyone,
i have some problems with repairing/reinstalling Avast (free). Not sure if it was caused with latest windows or avast program udate, but my PC froze yesterday two times by streaming online videos - had to do hard reset. So i decided to use older restore point of windows. I don´t know if that helped to the original problem
But the main thing is, avast stoped working. I have tried nearly everything, nothing helped.
Another restor points
Repair/uninstall in cotrol panel - do nothing
avastclear.exe - gave mi this: The stub cannot run installer/updater executable ‘C:\Program Files\AVAST Software\Avast\setup\Sfx\instup.exe’ (code 0x3)
I red here about same problem, so I ran FRST, my logs are uploaded with this message.
Could anyone write the Fixlist for me?
Thank you very much a sorry for my english
Zdenek

Thank you essexboy, it worked, avast reinstalled, perfect ;D
Only to the original problmem, could it be a virus or somethnig wrong in Vista, with that crash by video streaming?
For example youtube, last 1-2 month, when watching CPU is on 100% and the video is “skipping” and yesterday PC two times colapsed. Never happened before. So I blamed avast, but it seems to be the problem somewhere els.
I tryed ccleaner, adwcleaner, but ther is no difference.
On more thing, when PC is still, CPU is skipping from 0 to 10% every 5 second… 
I connected it to this process: WmiPrvSE.exe - NETWORK SERVICE - WMI Provider Host
But here my skills ends
I am suspicious of net framework and task manager, but thats all.
If you have any suggestions, I would be happy 
Thank you for your help.
Zdenek
PS: fixlog attached
It is Vista I am afraid apart from XP and 7 the interim windows were prone to crashing or just generally misbehaving. There was no malware evident on the system
WMI is a known high CPU problem for Vista and 7

OK thanks
I understand, when it si going to be worse, just to do new windows installation…
I was thinking about malwarebytes could help, but as you say, probably not.
Last thing, I see on my disk folder of the FRST with Quarantine, where the rest of the original avast is. Can I try to delete it and the FRST too? It is 0,5 Gb…

Nope let me remove them 
Remove tools
Download and run Delfix
