Okay, I have to say, I'm not a total computer newbie, but this time I'm completely stumped.

One day, I found out my AVG.exe and Spybot S&D exe files (along with several other stuff, like motherboard programs) were just missing. I heard the hard-drive spinning, but I wasn't doing anything too intensive, so I opened up my processes and saw this one process that was a bunch of numbers, so I ended that and the hard-drive stopped spinning. Lucky I caught that fast, because I think that was deleting some of my stuff. From there on I knew something was wrong. First, I downloaded the latest AVG definitions tried rebooting into safe-mode, but when I did this, once I picked safe-mode from the start-up menu (via F8 on reboot), after it loaded some files, it would just restart. So I started trying to install various anti-virus programs, but they all failed:

AVG - I got an error saying I couldn't install it because of a missing exe file or something.
Kaspersky - It says I don't have admin rights.
Spybot - The exe file gets deleted the moment it's installed.

The funny thing is, I'm the only account on my XP, and it's the admin account. One thing I have been noticing lately is that when my screensaver runs, I get logged out. This didn't happen before. I also now have to click on my account to enter windows on a startup, which also never happened before. It would usually just go into windows using my account, but when I had to click on my account to enter, I thought nothing of it. But it may be a clue to some of you.

Then I tried running online scans, Kaspersky told me there were infections (but the online scan doesn't remove anything), I ran several others: Trend would get stuck, several others could not update and such.

The only one I got to run and actually remove some files was BitDefender. It picked up some files in C:\WINDOWS\exefld, and basically they were a bunch of numbers with an exe extension. I restarted, tried to boot into safe mode but failed. The problem was still there, so I opened that folder and the icons were like two keys.

While running these scans, a window popped up saying my windows files were changed and it might screw up windows. So it wanted me to reinstall XP.

I started to realize this was a rootkit, so I tried to find some removers.

F-secure - I couldn't finish updating
Sophos? rootkit remover - can't install, don't have admin rights.

So now I'm stuck. I have ran chkdsk and it was fine. I haven't had a chance to get a HJT log yet, but will do so soon.

Basically, I can't install any virus removal software, I can't boot into safe mode, my windows files are being changed and exe files are disappearing.

Please help.

EDIT: Oh yea, I've checked my processes as well, and nothing seems to be irregular, but I'm not too sure.

Please read and follow all instructions in the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". You may have performed some of these steps already. If you can't perform a step, then skip and continue with the next. In step #9 there are instructions for downloading HijackThis and creating a log. (This is a self-extracting version which will automatically install HJT in the proper location.) If using Windows Vista, be sure to Run As Administrator.

If HijackThis will not run, try renaming it. Open the HijackThis Folder, right-click on the HijackThis.exe file and rename it Scanner.exe. Double-click on Scanner.exe (which is still HijackThis) and then run your scan. If needed, change the .exe to something else such as .bat, .com, .pif, or .scr. Example: Scanner.bat or Scanner.com

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very 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 "bump" your post or 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.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".
