Please download the FRST 32 bit or FRST 64bit version to suit your operating system. It is important FRST is downloaded to your desktop.
If you are unsure if your operating system is 32 or 64 Bit please go HERE.
Once downloaded right click the FRST desktop icon and select "Run as administrator" from the menu"

If you receive any security warnings, or the User Account Control warning opens at any time whilst using FRST you can safely allow FRST to proceed.
FRST will open with two dialogue boxes, accept the disclaimer.

  1. Accept the default whitelist options,
  2. If the additions.txt options box is not checked please select it.
  3. Then select Scan

Frst will take a few minutes to scan your computer, and when finished will produce two log files on your desktop, FRST.txt, and Addition.txt. They will display immediately on the desktop, but can be reopened later as a notepad file.

Adware Cleaner

  • Download AdwCleaner and save it to your Desktop
  • Right-click on AdwCleaner.exeand select
    Spcusrh.png

    Run as Administrator
  • Accept the EULA (I accept), then click on Scan Now
  • Let the scan complete
  • Once the scan completes, make sure that every item listed in the different tabs is checked and click on the Clean & Repair button
  • Subsequently you may be asked to Run Basic Repair. This is optional. I would suggest holding off on this for now.
  • Once the cleaning process is complete, AdwCleaner will ask you to restart your computer
  • Close all other open windows and allow it to restart
  • After the restart, Notepad will open with the AdwCleaner cleaning log
  • Please Attach the contents of that log into your next reply to me



FRST Fix.

Download attached fixlist.txt file and save it to the Desktop. NOTE. It's important that both files, FRST/FRST64 and fixlist.txt are in the same location or the fix will not work.

Running this on another machine may cause damage to your operating system Run FRST/FRST64 and press the Fix button just once and wait. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
