I am still running two Windows XP machines. They both had become very "doggie"!
Stumbled across adwcleaner_6.046.exe the other day. Instructions were to run it, follow with a full sweep by Malwarebytes Anti Malware and finish with HitmanPro.exe
I followed instructions! Found 22 files on this computer and 84 on the farm computer! Both operate almost like new now!
Worth a try.
