I think I've got a bad infection on my computer. I used AVG to scan and it came up with: C:\WINDOWS\system32\shell32.dll. For the status it says "changed". I don't know how to get rid of it! I keep getting pop ups, mostly a fake Windows Vista 2008 scanner thing that says I have all kinds of viruses on my computer and trys to get me to download some kind of update thing. I just exit out of it but it keeps popping up. Please, can someone help me? :thumbsup:

Reported changes in system files such as kernel32.dll, wsock32.dll, user32.dll, shell32.dll and ntosknrl.exe are normal for AVG.

There are many valid reasons for those files to show changed, a Windows update, file system check that replaced them if corrupted, and others. As long as AVG doesn't say they are infected it is ok. If it continues to show changed, delete the following file(s) in the C:\ directory and AVG will create a new one(s)...AVG7DB_F.DAT, AVG7QT.DAT

kernel32.dll, wsock32.dll, user32.dll, shell32.dll and ntosknrl.exe have "changed"

It is normal that AVG shows that files, the MBR or Boot record to have changed. These are done during normal maintainance, when you or windows updates files or have had to correct errors on the drive. The only time that you should worry is if they also show as infected.

To get AVG to quit showing them as changed...

Changed File Alerts

However, if you're getting pop ups and prompted to download rogue/bogus software, then do this:

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.
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. Reagardless 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.
