Avira fixes antivirus update that crippled many PCs

If you use the Avira antivirus program, you likely got hit with a big problem for a number of hours late on Monday and earlier today. ZDNet reports that the software program downloaded a new update, along with a new antivirus definitions file, that caused the software to falsely detect malware in major PC programs.

The 8.2.10.64 update for Avira, for Windows XP, Windows Vista, and Windows 7 PCs, caused the software to say that malware existed in programs such as Explorer, Internet Explorer, Notepad, the Windows Task Manager and many more. In addition, the faulty update also blocked the use of a number of other Microsoft and third party programs.

This issue apparently lasted for about 12 hours for the many millions of PC users who have the Avira software installed. Earlier today, the company announced via its Facebook page that it has released yet another update to the software that should fix the problem. The message added, "We deeply regret any difficulties that this may have caused you. Thank you for your patience and understanding!"

This update issue only affected users of the paid version of Avira. The free version of the software does not receive the same kinds of updates and thus was not affected.

This is the first time I heard of them goofing up. Pretty much all the others have done it by now.

THIS.... to all people that whine and threatening to move away from Avira.

No doubt!

Like any numb nut whiner is going to give up their paid versions just like that! Then again, they may as that is what made them numb nuts anyway!

Yep,
The majority of AV's have had this happen at least once, but this one didn't totally ruin computers like the Avast boo-boo did a while back.

Hey i`m not defending Avast or Avira here (QA should make sure this never happens) but it did "ruin" some computers as it killed and quarantined some critical components such as explorer, dllhost, etc.

"Those are just some of the false detected Windows processes. Avira sometimes kills them and stops Windows from booting."
Luckily it was the ProActiv application blocking component (removed for the time being i think) which caused this and it`s not enabled by default (opt-in), that`s not to say many weren`t affected by this and i feel for them, but like you mentioned it has happened to pretty much every AV company at some time!
Luckily it seems some were able to resolve the issue by booting into Safe Mode.

Haha so basically "don't pay us if you want quality updates". Well done QA team

Oops, reminds me of AVG. MSE for me.

Indeed and today started the new pre-release beta program for it on Connect, so I'm going to stick with it.
