I can't boot in safe mode because mi PC crash. Thanks

Try to uninstall Avast through the add/remove programs section. Run an anti-spyware program like Spybot and see if it picks up on anything. If it doesn't, then try to reinstall Avast. And if you manage to do that successfully then try to update Avast and run another scan to be safe. Also, some added advice, quarantine the viruses or trojans first so that you can get info on them in case you need to download a certain program to completely erase them from your system. You can delete them from the chest afterward. Internalrage

I don't get it? Avast is enthusiastically recommended by more than a few people on these forums. But, where the heck are they when there's a problem with it? Please let us know if you found someone's advice to be helpful.
