Normally I use Excite.com as my home page. Tonight I did a search and found that my regular Excite search function has been hijacked by Dogpile.com. I tried doing System Restore to an earlier time, that didn't get rid of it. Has anybody else had this happen? How do I get rid of it? I'm going to try a full system scan for adware/spyware, but other suggestions would be appreciated.
