    Exclamation Major problems with BitDefender on 64bit systems

    Seems that BitDefender is seeing its own files as trojans!! Also some Windows files.

    Antivirus Support & Malware Database | BitDefender Consumer Support

    BitDefender update cripples 64-bit versions of Windows

    Looks like the same problem could be affecting other AV software too - F-Secure, G-Data and Bull Guard.

    Bit Defender 64 bit goes ballistic - Wilders Security Forums

    Either they didn't check the update before releasing it, or someone 'got at it'. There's even a problem applying the patch. Difficult to do when Windows files have been deleted or held in quarantine.

    Note: I just got a RSS alert from Bleeping Computer pointing to the link above. That's nearly 8 hours after the post!

    Right Bull Guard was affected. Funny you mention this I was on Yahoo answers yesterday and a post came over with the BitDefender Trojan complaint, thinking it was just another trojan had the user run a Malwarebytes scan to check. In less than an hour about 10 to 15 more posts came with the same trojan complaint.. All 64-Bit and BitDefender Anti Virus.....

    This a major problem for BitDefender and others. Thankfully, it's only affecting 64bit os. Imagine the fallout if it was affecting 32bit machines.

    The above post has popped up all over the net. Damage limitation in action. Let's hope it works!

    As far as we are aware, BitDefender does work very well now, but at the time this thread was created, there were massive problems with 64bit systems, as admitted by BitDefender themselves in the post you quote.

    In view of that, it's hard to see what the purpose of your post was.
