A software vendor has released a new update that should alleviate the bugs that invaded University of Illinois computers on Wednesday.
An update to the antivirus software that protects most UI machines appeared instead as a virus Wednesday morning, according to Mike Corn, chief privacy and security officer for the campus. Machines running Windows XP are affected.
That made the computers have problems with restarting, Corn said. He said the problem initially was thought to be a "zero-day" virus, a brand-new one, but was quickly determined to be caused by a bug in the antivirus update.
"Now we know that at least we are not under attack," he said, "but there's lost productivity on campus."
"Computers affected by the buggy (software) may reboot frequently or report the virus W32/Wecorl.a was found," Corn said in a universitywide e-mail.
McAfee, the antivirus provider , had issued a new update, and most UI machines would fix themselves by updating the antivirus software. The problem was not limited to UI machines., but was affecting McAfee customers nationally, Corn said in the e-mail.
Updates will be posted at the website of the campus information technology department. He said those employees who use the university-provided antivirus software on home machines and run Windows XP also should check the website, but that the update has been pulled from circulation.
