Hi. thanks in advance for the help!
My buddy asked me to cleanup his wife's computer and i have done my best. The original complaint was popups, and i am not seeing any now. But I am not confident that there is no lurking malware.
what i have done:
1. I used windows defender, updated it and scanned and let it remove "BrowserModifier:Win32/Prifou"
2. I installed Zemana Antimalware and it found and removed several items ("Detected Objects : 19")
...after removing these i rebooted and scanned again and received a clean scan. I uninstalled Zemana, ran windows updates, and updated flash.
Since then the laptop seems to be operating normally, but I know I am not very good at this, so i am seeking your help.
THANKS!
Xian
