I have tried everything from multi different pages on how to uninstall this avast and nothing works.

Im sure what you are going to tell me will be something ive already done,safe mode nope dont work,uninstall utility nope dont work,etc.

I try the uninstall utility and get an error says spamming.Ive tried so many different things its driving me nuts and i know its a virus because it cant be this hard.

Ive watched youtube how to’s ive went to avast themselves nothing.

I guess ill have to just reformat my whole pc,that will alaways work but would rather not.

After all the things ive tried it no longer shows up anywhere cept in control panel and C: drive and even then it dont allow me to remove it.Anything i do that involves avast gives me many different errors now,yet it still remains.I cant even try to reinstall it,it just gives me error messages as follows:

Control Panel Unistall says…Error reading product data from C:\program files\Alwilsoftware\avast5\setup cannot continue.

Aswclear says…the avst self protection module is enabled.for this reason the operation cannot be completed.To complete this operation,either run in safe mode or disable the avst self protection via settings troubleshooting page.(which of course i cant get to without error message)

Try to reinstall and i get same message as from control panel uninstall then when i close that error window i get this…an error 0 (00000000) has occured.Last performance was:spawning.

Theres more but im tired of typing,please help,if its possible lol.
