Internet Explorer Homepage Keeps Changing on me!

Hey,

I'm new to this site as its my first post and well I have a problem. The other night I believe malicous software got into my system, which I got rid of, but my Internet Explorer homepage was changed to "about:blank" but when i open explorer it takes me to some secruity website wanting me to download their software and pay for it. In the control panel I've tried changing it back to msn.ca under internet options but as soon as i close it it goes right back to "about: blank" Is there anything I can do guys? Thanx

 

sounds like you have a hijacker running. may i suggest posting in the malware forums?
