A friend of mine is having some problems with Internet Explorer after getting rid of spyware with cwshredder and spybot S&D. She opens up IE and it shows her homepage (www.google.ca), but then switches to http:///. In the same way, if she types in another page, it'll show momentarily, then switch to http:///. She's got Firefox and Windows Explorer hasn't been affected, so she's not really suffering in the use of her machine, but she's contemplating reformatting because she hasn't got a clue as to what's going on with her machine.
Any ideas?
