Everytime I open up Firefox, instead of opening my homepage it keeps opening this website called "http://www.%snf%.com/". I have no idea what it is or how this happened, but I am sure some app is doing this and I don't know what app to uninstall. Anybody else have this problem before?

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.


Do a malware check with several malware scanning programs on the Windows computer.

Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
