I'm not sure where to start here. I think you should not have waited as long but you probably already know that. What is it that you download to scan with? Perhaps if you checked add/remove programs in the control panel for some things that you don't recognize. Can you get into there at all? Another possiblity would be trying to get to system restore and go back to a time before you got infected. It may not remove everything but it might help enough to get some scanners downloaded at working. You could also try going into safe mode and scanning with whatever you are scanning with.
I have been having nightmarish problems with my computer recently, and was wondering if anyone could help me. Before I begin, I use Windows XP, but don't know any further specifications (except that it was fairly new and recommended to me by a friend as a top-of-the-line gaming computer, and has the words "Systemax Tiger" on the hard drive).
About a week ago, I was surfing the web when I noticed my computer when I noticed that my computer was operating very slowly (admittedly, I had downloaded some suspect files only a few minutes earlier). Instead of doing the smart(er) thing and using Ctrl + Alt + Del and seeing what process was taking up so much attention, I just decided to restart. As the computer closed down, it showed a somewhat alarming message, to the affect of, "The changes will be completed once your computer restarts."
As soon as the computer booted up again, the trouble began. There were several copies of something called "Desktop Search" running, which created a toolbar in the lower right corner of the screen and slowed my comp down significantly, and I started getting pop-ups even when IE was closed. Furthermore, icons would appear on my desktop without me doing anything, and at least 30 processes were running that I didn?t recognize (some that keep popping up are 'powerscan', 'rundll32', and several beginning in 'rzz', if that helps). I downloaded a free spyware remover from Cnet, and removed everything it said was dangerous, but I ran a scan a few minutes later and virtually everything that was there the first time (128 problems) was there the second time (123).
I generally kept the computer off (it seemed to get worse every second), but accidentally left it on when I went out on Saturday. When I got back, there was about 50 pop-ups, but once I cleared them away, both all the files on my desktop and the "Windows" toolbar at the bottom that shows what programs are running were missing. When I shut my computer down, it said that 'I-Explorer' refused to quit and that I had to end it now. I did, and when I tried to reboot, it asked me if it could scan for errors. After the ten second waiting period, the screen simply went blank and went to the "Welcome" screen, and then informed me that, again paraphrased, 'A critical error has occurred, and Windows must shut down." It allowed me to send a report to Microsoft (which I did), and then shut down. I have since been unable to get that same error message to return (the computer now just starts up, I get a ever-so-brief glimpse of the desktop icons and the 'start' bar, and then the screen goes blank (except for the pop-ups).
All right, this post is longwinded enough already, so I will cut to the chase: Does anyone know what the problem is? If so, can it be fixed, considering I essentially can't run any programs? If the answer to either of those questions is no, is simply erasing my hard-drive a viable option, again without running any programs (everything on my computer will be easy to get back, should I chose to do so)? If so, how would I go about doing it? Thanks in advance!
