I think I deleted the services to run avast! How to go back since my antivirus totally disabled. Nothing I can not use it or delete it! HELP!
When more than avast uninstaler want to delete this throws me!
Why don’t you follow the suggestion and run the uninstaller in safe mode?
I do not know how to fix this regime 
Restart the computer, and press F8 before Windows start booting. You’ll get a number of options, including “Safe Mode” and “Safe Mode with Networking”.
I tried now … I do not have that option F8: (
I’m quite sure it’s there - but you might have to be quick (on the other hand, sometimes BIOS also uses F8 as a special key - in which case it might be a bit tricky to find the right moment to press it, not “too soon” to enter the BIOS, but rather to invoke the Windows boot menu).
I tried many times, not … I saw somewhere that this can be start-search-msconfig something like that …
Yes, you can try that as well - start msconfig.exe (e.g. using the Run command - Win+R), switch to Boot (or Boot.ini, depending on the OS) page and check the Safe boot (or /SAFEBOOT) option.
