hey there all :D

Just over an hour ago i reformatted due to this trojan (IRC/Backdoor.sdl). After i had reformatted and re-installed XP, set-up my internet connection etc the virus was still there!

I have AVG 6 which was unable to move the files to the vault. There are 2 infected files:
Winregs32.exe
Msnmssgs.exe

I have ad-aware, but after it's first run the reference file seems to have gone astray, and will not update to correct itself.

I found a thread related to my problem, and followed the steps using Hijack This, although my log was completely different. i managed to follow it, but when coming out of safemode and re scanning, the infections were still there.

However, after running AVG again it was able to heal the files. I am unsure that i have cured it, as my broadband connection details say i have a lot of traffic, but i have no programs open which would need it! Please could you look at this log, i would be over the moon if i can sort this with your help <_<

We can definitely help you, but first you need to help us. The first step in this process is to apply Service Pack 1a for Windows XP. Without this update, you're wide open to re-infection, and we're both just wasting our time.
Click here: http://www.microsoft...p1/default.mspx
Apply the update, reboot, and post a fresh Hijack This log.

Some hijacks interfere with the installation of Service Pack 2, so we'll hold of for now. When we're finished cleaning your computer we highly recommend installing SP2. Click here: http://windowsupdate.microsoft.com/.
-or-
It's a very large download, so if you're on dial-up, order a free CD here:

Thanks for the quick reply =)
I have Sp2 installed now.
looking in the task manager there are 3 processes that seem to directly effect my connection. as soon as i had ended them, surfing speed was back to normal. these are as follows:
crss.exe
wdrk32.exe
sysmsvc.exe

My most recent logs are shown below. The log was taken after a full system scan with AVG 6, Ad-aware and spybot; all of which i consider to be up to date!

You may wish to print out a copy of these instructions to follow while you complete this procedure.

Please save Hijack This in a permanent folder (i.e. C:\HJT). This ensures backups are saved and accessible.

Please go offline, close all browsers and any open Windows, making sure that only HijackThis is open. Scan and when it finishes, put an X in the boxes, only next to these following items, then click fix checked.

O4 - HKLM\..\RunServices: [MsWindows SysDate] sysmsvc.exe
O4 - HKLM\..\RunServices: [Sygate Personal Port] crss.exe
O4 - HKLM\..\RunServices: [Win32 DRK Driver] wdrk32.exe
O4 - HKLM\..\RunOnce: [Win32 DRK Driver] wdrk32.exe
O4 - HKCU\..\Run: [Win32 DRK Driver] wdrk32.exe
O4 - HKCU\..\Run: [Sygate Personal Port] crss.exe

Please reboot into safe mode - How do I boot into "Safe" mode?.
Be sure you're able to view hidden files, and remove the following files in bold (if found):


C:/sysmsvc

Congratulations! Your system is CLEAN <_<

How do you prevent spyware from being installed again? We strongly recommend installing SpywareBlaster (it's free for personal use) Click Here.

Prevent the installation of ActiveX-based spyware, adware, browser hijackers, dialers, and other potentially unwanted pests.
Block spyware/tracking cookies in Internet Explorer and Mozilla/Firefox.
Restrict the actions of potentially dangerous sites in Internet Explorer.
Consumes no system resources.

Download, run, check for updates, download updates, select all, protect against checked. All done. Check for updates every couple of weeks. If you have any errors running the program like a missing file see the link at the bottom of the javacool page.

It's also very important to keep your system up to date to avoid unnecessary security risks. Click Here to make sure that you have the latest patches for Windows.

These next two steps are optional, but will provide the greatest protection.
1. Use ANY browser besides Internet Explorer, almost every exploit is crafted to take advantage of an IE weakness. We usually recommend FireFox Posted Image.
2. Install Sun's Java. It's much more secure than Microsoft's Java Virtual Machine .

It's okay to delete the Hijack This folder if everything is working okay.

After doing all these, your system will be thoroughly protected from future threats. :D
