Hi,

I just got computer back from repairs yesterday. They had taken away the CPU. Now, while working in Windows XP, I find that the scrollbar sometimes jumps around randomly. Sometimes it just goes to the bottom and refuses to budge. I don't have any spare mouse lying around, so I decided to clean both the keyboard and the mouse (unearthed a lot of dust; but that's another story), but that didn't solve the problem. I have an Ubuntu Live CD as well as copy of Windows 7. I ran both of them, and found that the problem was there in Linux, but it was almost non-existent in Windows 7.

What I am asking is, could it be a virus? Can anybody help me out?

Thanks.

It appears as if something is askew. So let's at least get a scan.

Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.36) 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.

Thanks for the advice. I installed and ran a Quick scan. That found nothing, so I went for a full scan. But that was interrupted just when it was scanning the last drive, which has Windows 7. Till that, it didn't find anything either. Here is the log anyway.

And there is something else. When performing the quick scan, I found that the modem's 'send' and 'receive' lights were blinking like crazy, like it would when downloading a file. Could that be something else using the internet to send and receive messages while I am not using the internet?

Hello this doesn't appear to be malware. It seems like a software conflict or a faulty OS install. I would ask in the XP forum or consider a repair install. I don't know how long ago this started or how long after the repair. but you may be able to boot to restore the PC back to a a point before this occurred and see if it stops.
