Worms and trojans can’t be repaired. You must delete them. If avast cant delete the file from windows boot into safemode and try to delete the file

I Tried Already
And I can’t Delete Too in the safe mode.
what I need to do?

have you try the stand-alone avast cleaner??

Hm, please update your Avast defs. Sounds like a false alarm to me. Is the folder and filename complete? and if so, please search the registry for that file.

well , now I have a gobot Virus or somthing like that
I can’t do nothing in the computr like this
what should I do?

Identify the filename and location of the gaobot, kill the "gaobotfilename"task and delete the file (or let Avast do it for you) or do it in safe mode (or let Avast do it for you) or just disable the startup of the gaobot( there are allmost zwo startupentires to that file) by using MSCONFIG.EXE and delete the file after restart.
