Well more or less what it says in the title. I got infected with a trojan downloader and in the course of removing it I may have messed with the win 32 file. It was a pretty stupid move on my part and neither registry fix or mechanic have helped.

Basicly every time I try to windows update it crashes. It crashed when I tried to search limewire. Blue screen comes up and tells me windows shut down.

And also sometimes when I load up it says there was a system error and when I send a report it begins a 1 minute timer til shut down.

Here is my log file and I would greatly appretiate any help I can get (I already lost one computer cause of something like this)

Hi Peter,

Sorry for the delay, the forum is very busy.

I don't see any signs of malware in your log. It looks clean, and you're running good security programs (AVG and Spyware Doctor). The only thing I don't see is a firewall, I assume you're using the Windows built-in (it doesn't show up in a HJT log). You should consider a two-way firewall, it offers better protection. Check out this tutorial for more information.

You mentioned limewire, that's probably how you got your trojan. If you want to keep using it, that's your decision, but I am obligated to mention that peer-to-peer programs make it easy to pick up malware unless you are very very careful with your downloads.

Regarding your problem, It may be that your system has been damaged by malware, it's also possible that you damaged it in removing the trojan. I don't know what procedures or tools you used.

Either way, what will be needed for diagnosis is the blue screen message that accompanies your crashes. From now on, when you system crashes, write down the exact error message, including all the strings of numbers and letters that appear on the screen. You may get different messages with different crashes. Write them all down, and note what you were doing when the crash occurred.

The best place to post this information is not here. You should start a new topic at the Bleeping Computer Windows XP forum. The people there are very experienced, and they know more than I do about problems like yours. Pay special attention to posts from Moderators and BC Advisors.

Since it appears you are using scanners regularly, I don't think there is much point in asking you to do any more here, except perhaps to do a rootkit scan. If that comes up clean, your next step is definitely a post on the WinXP forum.

Download Blacklight Beta here. The link is at the bottom of the page ("click here to download"). You will get a page explaining the license, click I accept. On the next page, click the top link to download the Graphical user interface version. Save it to your desktop. When you double-click the icon, you will see another license page. Select the I accept radio button and click Next. On the following page, click the Scan button. When the scan is complete, Blacklight will fix anything it finds, then tell you it is finished. Exit the program. You will find a log file on your desktop, the filename will be fsbl-2006xxxxxxxxxx.log. The first four digits are the year, the next four are the month and day. This is a text file and can be opened with notepad.

Post the contents of the blacklight log to a reply here, along with any questions or further information you might want to add.

Thanks for the help man, the scan came up clean so I think it must be something else.

I will keep note of the error messages and let you know, thanks again

Hi Peter,

Quick work! The Blacklight scan is clean. Your problem is not malware. As I said before, please post the error message(s) to a new topic in the WinXP Forum. Here is a link.

You will get much quicker answers and better advice over there. My area is malware, I also know something about hardware, but this kind of operating system repair I have relatively little knowledge of. Also, unlike here, anyone can post answers on that forum, so you will get the benefit of several people's experience.

Good luck --
