If you start in safe mode you can delete this DLL files contents using Edit. This will also let you know what processes are using it cause you will then get errors. then go into regedit and remove its string from everything.
Awesome im trying to install AVG again and i says i have to remove it but all thats left is this crap
Found within AVG anti-virus. Removing is diffucult and will cause internet connectivity failure in both wired and wireless function. Used SysRestore to undelete and problems fixed. Leave it alone.

It was fine for awhile then I got malware, PUPs, etc you name it and deleted it, then reinstalled and when i downloaded it must have been corrupted because my computer was so messed up, Im lucky it didn't die! What has me exasperated is now i can't get it removed from my computer. It says to reboot for update and i did it and stupid thing popped up again and again and again! Tried to uninstall it and it wasn't going anywhere! Its a shame because I really did like it at one point but not anymore! I'm having to use so many resources to see it i can get it off my computer and its been a nightmare
