BitDefender says the problem occurred Saturday morning with a faulty update for 64-bit Windows systems that caused multiple Windows and BitDefender files to be quarantined. The bad update causes the anti-virus program to flag thousands of legitimate Windows and BitDefender program files as a threat called “”FakeAlert.5″.
The Romanian software firm said the glitchy update has been removed and that the company is working on a fix for the problem. BitDefender’s user forum has lit up with complaints from customers, and the company appears to be fielding quite a number of inquiries on the problem via its Twitter page.
“We are creating a patch that will restore all quarantined files,” the company said in a statement on its site. “The patch will be available shortly. We apologize for this error and we will work to prevent this from occurring again in the future.”
BitDefender has posted partial recovery instructions for users who are having trouble booting up Windows after this bad update, although several apparent users commenting on the company’s Twitter feed indicated they were still unable to boot after following the instructions.
Meanwhile, Bitdefender representatives on Twitter are warning users that malware writers already are taking advantage of the situation, and urging users to download the fix — whenever it is made available — only from BitDefender’s Web site.
