It was clean install AvastIS. I've used to work with Kaspersky IS earlier. During the Avast install blue screen appears. After rebooting i can't start install Avast IS again. There was error while extracting files. I've tried to uninstall all Avast programs, but there wasn't anything on my programm list. Then I've tried to delete Avast folder manually (in c:\Program Files) but there was problem with permissions. I did this on my administrator account so i was suprised that i can't do this. Then I tried to start win7 in safe mode and fix that(with setup repair option) and then the real problems begins. Now booting ends each time on system recovery console. When i choose language and start, after a few seconds it shows error and in details there is something about - aswrvrt.sys is corrupt. Everything else is finished successfully. I've options: shut down, reboot, send info about, error.
In Command Prompt i've opened notepad.exe and through file-> open... i've copied my desktop files on second partition and do the instructions from other topic:
