Just been down the last couple hours. A very nasty virus/malware of some kind. Didnt find out what it was called. What did it do? 1./ Hijacked DNS so that every 1 in 5 internet pages would appear with its fake "Windows Firewall security" comment, click here to continue, click there to download... 2./ It BLOCKED the website for Malwarebytes completely. 3./ It BLOCKED the Windows installer for Malwarebytes. It would freeze at a certain point so that the installer would crash. 4./ It would automatically deactive McAfee Antivirus ENTERPRISE after 5 seconds. If you reenabled it manually, 5 seconds later, it would turn off again. 5./ SUPERAntispyware would install, and find all sorts of rubbish, and remove some, but points 1, 2, 3, and 4 would still be there! It was Superantispyware proof! 6./ No joy tracking it down with sysinternals process explorer. 7./ But I found this: RootRepeal http://rootrepeal.googlepages.com/ This managed to find and "force delete" the b14tch. I'm a bit worried it might have still left some damage somewhere, but will get back to you with more info if I get it. BE CAREFUL. Something nasty is out there. Keep you antivirus/malware shields up!
