Avast detected Steam as a virus and broke it

[Carcayu]

Yesterday Avast deected Steam as a virus and I wasn't able to play any game at all from my Library. Today, with Avast uninstalled, it's still all crashed. I'm still unable to play any of the games I've been playing; for example:

- When trying tu run LEGO The Hobbit an error pops up about not having Shader Model 3
- When trying to run GTA IV it just crashes after an unexpected error
- When trying to run Skyrim, it says that my display doesn't support the selected resolution (no matter which resolution I choose)
- When trying to run Primal Carnage: Extinction, get a launcher error.

What do I have to do to play again my games?
FEZ is the only one that works!

P.S.: I've uninstalled/reinstalled Steam and all my games, still not working.

Maybe try to whitelist steam on avast.

Avast has been replaced by AVG, and Steam has been already added the AVG's exception list.

No just no, AVG is garbage. Once got a virus and it refused to fix it unless i payed. Might wanna look for a better anti-virus or just stick with windows defender.

Well, it doesn't change the fact that Avast can't be blocking my games, but somehow it has broken my machine...

Well i'm not really a avast expert. You might as well stick with windows defender

In such cases undo the quarantine.

Generally:
It should block attempts and you should make further choices.
Thats the right setting.

As I've said, Avast is no longer installed on my computer, so it's quarantine shouldn't affect any more.

Have you tried simply reinstalling/refreshing Steam?

If something was put in it, uninstalling avast doesnt free it.

And the suggestion is valid for any antivirus

I am really not sure what you talking abut, using AVG for a long time all ready, works great, never ask me to pay, and removed Bad Software that i download
Only down side it has is it dose detect things that are not viruses, at times, but you can allow them and all good, and better safe then sorry
Also from what i pick up, seem to be one of the only once that block the Malware that was going around Steam.. so.. ya..

@OP

Did you try to refresh Steam? (sometimes its better then reinsatlling it)
Also dose Steam start up at all?

I had the same problem, avast completely murdered my steam client by detecting all its files as false positive.

With all the fixes i did (verify cache, reinstalling steam, reinstalling avast, disabling firewall etc.) i went to Control panel/Hardware and sound/Device manager and went to Display adapters tab and right clicked on the driver and selected update driver software, you must wait for the driver to automatically update, restart your pc and your games should be working again.

[Muppet among Puppets]

Why do you have autoquarantine enabled?
Shouldnt the antivirus block malicious files it knows and then you can decide what should happen with them?
