AVG update cripples some Windows XP systems

On Tuesday A update for AVG 8 suggested that a Windows system file is a Trojan horse, and users who delete the file form the system could leave their Windows XP systems endlessly rebooting or unable to reboot at all. The problem only affects users of AVG 8 products running the Dutch, French, Italian, Portuguese, and Spanish language versions of Windows XP. AVG immediately sent out a corrected update to its customers, including those using the free editions of AVG.
