A bad McAfee update on Wednesday created some problems for users running computers with Windows XP.
The incorrect malware alert, issued today at 9am Eastern, resulted in computers with Windows XP Service Pack 3 to shut down and start on a continuous reboot cycle.
"McAfee is aware that a number of corporate customers may have incurred a false positive error due to incorrect malware alerts," McAfee said in a statement. "McAfee is working to address the problem with continuous customer communication and a new signature update. McAfee apologizes for any inconvenience to our customers."
