McAfee fixes update glitch that knocked BT users offline

The buggy update, which was issued last Friday, affected both home and enterprise users, with some suffering loss of access and others seeing errors in McAfee's antivirus software

McAfee has issued a hotfix for a buggy update that it pushed out last Friday, which caused some customers to lose internet connectivity.

The problem, which also caused errors for some within McAfee's antivirus software, hit both home and enterprise users. BT flagging up the problem for its customers on Monday, saying those using Windows XP, Vista and 7 may have been affected.

According to a McAfee note, the buggy update (DAT) files were numbered 6807 and 6809.

The security firm pushed out a hotfix, containing DAT 6809, on Monday. However, that hotfix was around 100MB in size, and McAfee warned it "can cause high bandwidth usage in large environments".

McAfee subsequently put out a smaller version of the hotfix, not containing DAT 6809, on Tuesday, but it pointed out that this hotfix would need to be followed by a "full DAT update".

The company is not the only of its kind to issue faulty updates. In July, a new Symantec SONAR signature set inflicted the blue screen of death on some Windows XP users.
