Apparently the computer virus Win32/Conflicker.B is still running around the net causing all sorts of problems.
In order to kill this threat Microsoft has done a few things.
Back in October they released Microsoft Security Bulletin MS08-067.
Microsoft has updated the Malicious Software Removal Tool to detect and remove variants of Win32/Conflicker.B. This update can be downloaded from the Microsoft Update site or through its KB article.
There is a KB Article specifically about the virus it self.
Microsoft is recommending that you immediately apply MS08-067 to all unpatched systems to prevent the threat.
