Yahoo Malware

When I launch Chrome instead of going to google like it should it immediately goes straight to Yahoo instead. I’ve read that it could be malware causing this but when I scanned my computer using AVG it said no malware detected. Would anybody know what is causing this?

Yes - I have that too but only on my laptop. My PC is not contaminated. Ihave googled cures for the problem, but just get bread-and-butter stuff. Thought I had cured it but only got two weeks and its back again.
