I've got a nasty one and really need the help of the experts!

I'm running WinXP SP2 on an Asus A8N SLI mobo with an AMD x2 4200 processor. This all started with a pop-up that got in somehow, and no way to close it. One click and the screen exploded with pop-ups, most of them were for fake anti virus software that were supposed to look like they were scanning and finding viruses. Then a few of my running processes that have to do with software updates popped up some error messages (Adobe & Google updates mostly). At some point the computer froze, leaving no option other than the power button. When I rebooted and tried to use MalwareBytes the computer froze again. It did that with any anti-virus software I tried to open. When I did a search on Google it wouldn't let me click on the search results without taking me to some other site where the pop-ups took over again.

After several of these lockup/reboot via the power switch scenarios, the computer wouldn't run at all, and I had to do a repair install of XP to get it back. After that I did manage to get through a scan with Malware Bytes and SuperAntispyware which gave me a list of things to fix/delete. The computer was usable after that for a few days, so I downloaded and installed a fresh copy of Avira AntiVir Personal and scanned with that. It showed my computer was clean. I also downloaded Spybot Search & Destroy which found 5 entries related to Win32.TDSS.rkt in the Windows\System32 folder that were sys & dat & dll's preceded with the word SKYNET. I got rid of those and the computer was still working OK until I went to Google and tried clicking on one of the results. It redirected just like the first time and that started the whole cycle over again, including the lockups and the eventual need for an XP repair install.

Tonight I tried to do the trick with the text file on the desktop - renaming to SKYNETtest.txt, and the file immediately disappeared. So I downloaded and ran scans with RootRepeal. I got through a few of the tabs, and it showed that there is quite a bit of SKYNET related junk hidden in there, but the computer froze before I could get done with the whole scan. Had to use the power button again and thats where it sits right now.

I know it's going to take someone a lot brighter than me to come up with a coherent plan to fix this thing, so I'd really appreciate any help I can get. I think in the end I'm looking at a reformat because of the backdoor that may have compromised my machine, but I'd prefer to clean it up first so I can get my stuff transferred out in some orderly way and have some confidence that I'm not just moving the problems to a new hard drive.

Please advise (and thanks for listening to my babbling......)

Hello,

Now comes the hard part: waiting.

Now that you have posted a log, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days, perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses.

To avoid confusion, I am closing this topic. Good luck with your log.
