And now some shameless self promotion ;)

A screenshot of FreeFixer's scan result.Hi, my name is Roger Karlsson. I've been running this website since 2006. I want to let you know about the FreeFixer program. FreeFixer is a freeware tool that analyzes your system and let you manually identify unwanted programs. Once you've identified some malware files, FreeFixer is pretty good at removing them. You can download FreeFixer here. It runs on Windows 2000/XP/2003/2008/2016/2019/Vista/7/8/8.1/10. Supports both 32- and 64-bit Windows.

If you have questions, feedback on FreeFixer or the freefixer.com website, need help analyzing FreeFixer's scan result or just want to say hello, please contact me. You can find my email address at the contact page.
