My laptop is infected with something that redirects my yahoo searches to other links. I ran the Anti-Malware program, got the messages about the registry data items infected. I told the software to clean up the errors, restarted my computer and I still have the same redirecting problems. I've tried this procedure 3 times in the last week and my computer is not cleaned up. Help! What else can I do to get rid of whatever virus/spyware is infecting my laptop.
