McAfee Antivirus Snafu Crashes Windows XP MachinesBy Lawrence Walsh | Print
Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers
A poor signature file update falsely identifies a valid Windows process as malicious for PCs running McAfee AntiVirus on Windows XP machines. The fix causes PCs to go into a continuous reboot cycle that locks out users.
McAfee channel account managers and resellers are racing to get the word out on how to fix the antivirus snafu that arose this afternoon causing Windows XP machines to suddenly reboot.
The problem arose earlier today when McAfee pushed a new DAT file to
update its antivirus signatures. DAT release 5958 incorrectly tags valid
Windows XP SP3 system file "C:\Windows\system32\svchost.exe" as
containing malicious code. When it attempts to clean the file, it puts
the PC into a continuous reboot cycle that effectively results in a
denial of service.
