I had AVG AntiVirus FREE installed and it was working perfectly fine even yesterday. So today I opened my Start menu and typed "AVG" and this error "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." showed up as I clicked it. I tried 'troubleshoot compatibility' (It recommended 'Windows XP (Service Pack 2)') and it didn't work. I also tried to delete the whole AVG but I needed permission from SYSTEM to perform 'delete' action and it didn't work. I also tried it deleting it via regedit through Software and Wow6432Node so I can reinstall it but the whole file is still there.

I did as you said and now there's another error (code 0xC0070643) saying "Waiting for watchdog service start failed". What now?
