Hello:

 

I have a computer owned by the family of a friend that is complaining about a large number of unwanted programs being installed on the computer. The family stated that some of those programs began opening pop-ups advertising various things, e.g. virus scans. One member of the family went through the control panel and manually removed several of the programs. Subsequently Ccleaner, McAfee, and MBAM scans have been run, each identifying varying PUPs and being instructed to remove them. According to the family most of the PUPs appear to be gone, however there does seem to be a small number (1 to a small handful) that reappear upon reboot.

 

The computer is running Windows 7 Home Premium 64-bit. At this point I am looking for advice on tools or techniques to verify the issue is confined to PUPs and there hasn't been a malware infection, and to identify any remaining PUPs and remove them.

 

I do not have regular access to the machine in question, however the friend does and will be able to run any scans, pull information, etc. as needed.

 

Thank you!

Tell your friend to download and use the following tools (in the order listed) which will search for and remove many potentially unwanted programs (PUPs), adware, toolbars, browser hijackers, extensions, add-ons and other junkware as well as related registry entries (values, keys) and remnants.

RKill created by Grinler (aka Lawrence Abrams), the site owner of BleepingComputer.
AdwCleaner created by Xplode.
Junkware Removal Tool created by thisisu.

1. Double-click on RKill to launch the tool. A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.

Important: Do not reboot your computer until you complete the next step.

2. Double-click on AdwCleaner.exe to run the tool.
Vista/Windows 7/8 users right-click and select Run As Administrator.
  • Click on the Scan button.
  • AdwCleaner will begin...be patient as the scan may take some time to complete.
  • After the scan has finished, click on the Report button...a logfile (AdwCleaner[R0].txt) will open in Notepad for review.
  • After reviewing the log, click on the Clean button.
  • Press OK when asked to close all programs and follow the onscreen prompts.
  • Press OK again to allow AdwCleaner to restart the computer and complete the removal process.
  • After rebooting, a logfile report (AdwCleaner[S0].txt) will open automatically.
  • Copy and paste the contents of that logfile in your next reply.
  • A copy of all logfiles are saved in the C:\AdwCleaner folder which was created when running the tool.
-- Note: The contents of the AdwCleaner log file may be confusing. Unless you see a program name that you recognize and know should not be removed, don't worry about it. If you see an entry you want to keep, return to AdwCleaner before cleaning...all detected items will be listed (and checked) in each tab. Click on each one and uncheck any items you want to keep (except you cannot uncheck Chrome and Firefox preferences lines).


Close all open programs and shut down any protection/security software to avoid potential conflicts.

3. Double-click on JRT.exe to run the tool.
Vista/Windows 7/8 users right-click and select Run As Administrator.
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log file named JRT.txt will automatically open and be saved to your Desktop.
  • Copy and paste the contents of JRT.txt in your next reply.
4. As a final step, rescan again with Malwarebytes Anti-Malware.
