I recently purchased a PC from a friend. He's got some great software on there, and I really don't want to format the entire hard drive and start from scratch, but I'm running out of ideas. Help! This is the problem: When I search for something on Google, the results will flash, but then the first four results (obviously usually the answer I was looking for) changes to links to different search engines. For example, I'd type in 'Samsung', and the first results would say something like "Find 'Samsung' on 1020search.com!" and have a link to this new search engine. I'm assuming this is some sort of local virus, because it's only on my home computer that I've ever seen it. I've tried all the software virus fixes I have, deleted cookies, the whole bit, but can't seem to shake this problem. Has anyone encountered this before?
