Did you update your free copy of AVG 2011 today, in the hopes of evading a nasty bug? In a set of mildly familiar circumstances, the antivirus company has inadvertently unleashed an even nastier one. Users running 64-bit editions of Windows 7 and AVG 2011 are reporting a STOP error after a mandatory antivirus update this morning, which is keeping some from booting their machines into Windows at all. The buggy update has since been pulled and there are a couple ways to preemptively keep it from happening if you're staring at the message above, but if you've already been stung, you're looking at some quality time with a recovery disc or repair partition to fix your Windows boot files. Find all the solutions, including the preemptive ones, at our source link below.
