Friends computer was infected, can somebody help confirm it is clean now?

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

You did good!  Does the computer have up-to-date anti-virus and anti-malware shields on and data files?

For malware protection there is Windows Defender, not seeing any antivirus. Can you recommend good, free antivirus? And should i disable Windows Defender and install a 3rd party anti-malware, like Malware Bytes?

Windows Firewall is all the firewall you need.  Which Windows? 7? 8? 10?  If W7 -- MSE/Microsoft Security Essentials is quite adequate as an AV.  Malwarebytes AM [pay-for] is good!  SpywareBlaster [free version is enough, you only have to manually update maybe once a week] will safeguard the Host file for you.  W8 & W10 has Windows Defender, which is MSE-renamed; that WD along with MBAM [pay-for] will be quite adequate.  If the user plans on "doin' some surfin' in strange lands" -- then maybe a 3rd party AV might be better.

Emsisoft Anti-Malware [not free past 30 days] not only is a strong assertive anti-malware, it is also a strong assertive anti-virus.  If the user desires a 3rd party powerhouse, that pay-for certainly will do the job on two fronts!

Thanks for the recommendations! i guess i did forget the os, it's windows 10. i will urge him to buy MBAM to supplement Windows Defender or look at the Emisoft product.

Cheers!
