Windows users running 64-bit version of Microsoft’s Windows 7 OS face serious problems if they load the latest AVG anti virus software.Forums are running hot with claims that the OS is rendered unusable after users install the latest anti-virus software update.
The problem affects the most recent free update for AVG 2011, which was made available to users on Dec 1.
AVG has acknowledged that the patch can send some 64-bit Windows 7 machines in to a crash cycle, forcing a reboot of the computer from which it never restarts. The anti-virus company has withdrawn the update.
The UK Telegraph said that the problem is caused by one particular virus database update, which automatically forces the computer to reboot in order for the update to take affect. Upon restarting, the PC will register a “c0000135 error”, and will not complete the boot cycle.
