Was running AVG 6 (free) got rid of a couple of virus but had "C:\windows\system32\config\system.log" cannot open; not checked. When trying to open AVG it now flashes off screen in a millisecond. Tried to delete AVG but it says virus vault is not empty (it is empty)and flashes off screen. Tried to load EZ Armour free with Microsoft update cd but this now constantly over and over says wnetmgr.exe tried to connect to the internet (0.0.0.0) but was denied access by the internet lock. Do i have some virus controling \ blocking any anti virus i have \ try to load. HEEEEELP!
