EDIT: Really sorry, just realised I've posted this in the wrong place. Could someone please move it to the correct forum?

Hi everyone, quite a long description here, trying to be thorough. Any assistance you can provide would be most welcome.

Last night I clicked on a link (nothing particularly dodgy), and my laptop froze for a minute, before McAfee brought up a message saying that one of my files had been infected with a virus it called New Win32. I immediately ran a scan and it found a few of my system files were infected (winlogon.exe, csrss.exe and a couple of others), so I put them into quarantine.

However, when looking through the files myself (I'm a computing student, so I know my way around a computer pretty well, but my knowledge of complex virus removal is pretty limited), I found that in the Prefetch folder there were a lot of system files mentioned, including regedit.exe, which I'll go into more detail about in a minute. Around this time it also brought up an advert for SysGuard, which I closed and removed the executable file behind it.

I found a few other virus executable files, all of which I deleted. Then I went into regedit to see if I could find any registry keys that shouldnt be there. I didnt find anything at first, but suddenly my laptop decided to shut down, without me having told it to.

I reloaded in safe mode, but when I'm in safe mode it doesnt show me the taskbar at the bottom, just my desktop icons. I also can't seem to run many programs. For example, McAfee VirusScan won't run at all, and SuperAntiSpyware starts to run but then nothing comes up (although it does sit in the processes running). I tried to get onto the internet, but even when running safe mode with networking, I couldnt get a connection. I did manage to run Spybot, and it found a lot of things, mostly tracking cookies, but a few virus files, including one that was something to do with a Sentry (I shouldve written them down, but was very angry at this point). Also in Spybot, I found that there was an entry in System Startup for sysguard.exe, so I removed it.

I later ran Spybot again after reloading (again to safe mode), and it found sysguard again in the startup list. However, I did then find another set of virus files I hadnt seen before and removed them, I think they were causing it.

Something that did puzzle me was that the processes such as , which on my main computer are listed as being part of winlogon.exe, are listed on my laptop as being from system.ini. Could this be the virus in action?

When trying to load Windows normally, it hangs on the welcome screen for a long time, then finally shows me a blank desktop. It gives me the impression that it is loading, just very slowly. However, I don't want to just leave it like that because it seems like it's a virus doing stuff in the background.

Basically, does anyone have any suggestions as to what I can do, other than wiping the disk? I should also mention that although I got a CD from Dell when I bought my laptop, I'm not sure where it is, so I don't have access to my original Windows CD.

Many thanks for any help you can provide.

Hi and welcome. Let's try to run an MBAM scan and get a log. Here are some tips to get the tool to run if you have a difficulty. Please temporarily disable SpyBot for this.

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run..


***
Another work around is by not using the mouse to install it, Just use the arrow keys, tab, and enter keys.
***
Open up command prompt, type in following commands:
XP >> click the Start menu at the lower-left of your computer's desktop and select "Run". Type cmd into the Run box and click "OK".
Vista >> click the Start menu at the lower-left of your computer's desktop and Type cmd in the search box.

regsvr32 mbamext.dll
regsvr32 ssubtmr6.dll
regsvr32 vbalsgrid6.ocx
regsvr32 zlib.dll

****

If you cannot use the Internet,you will need access to another computer that has a connection.
From there save mbam-setup.exe to a flash,usb,jump drive or CD. Now transfer it to the infected machine, then install and run the program.
If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe so it will install on the hard drive.

Manually Downloading Updates:
Manually download them from HERE and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.

***
Try using a System Retore Point prior to the date of infection. You may be able to update and run MBam. Note this did not remove the malware.
Windows XP System Restore Guide


Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.
