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.

Also, go to the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for a good add blocker.
