IE 6.0 has “about:blank” as home page

I have a problem concerning IE on an WinXP SP2 pc. Because of some kind of malware/adware/spyware, the home page is constantly “about:blank”.

I’ve tried several different removal tools. Nothing works for long. Once I close the browser and reopen it, I’m back at about:blank as my home page.

I tried to execute the procedure using Registrar Lite. However, the procedure did follow along to what was on my screen.

Thanks in advance!
