I was having this same problem and had to reformat 2x. All was fine until this past Friday, and this same virus started taking over again. Now, I got past all the screesaver issues, I was able to delete some files before it got to the "screensaver" changing part. But now here are my issues. 1) Task Manager will not come up because the admin rights have been taken over by this virus. 2) When I go to "Start" Ctrl Panel, My Computer, none of those items are available 3) I get into "My Computer" by backdooring it, and my C:/ and D:/ drives are not available. I have to manually type them in to view them. The virus has gotten into my external hard drives as well, which the free version of avast is picking up, but the virus will not let me delete these files after being found through avast. When I go into the drive, I do not see these files. I am running programs that were mentioned earlier in this post, trying to get rid of this thing. Also, where the "Time" is, in the bottom right had corner, it has "VIRUS ALERT!" displaying all the time. Any help would be appreciated. Thanks!
