ClickSearchClick

[Amy]

I realised my computer was infected a couple of weeks ago, I ran an AVG scan and it seemed to go away apart from my homepage being ClickSearchClick for every first time I opened Internet Explorer. However, recently I had a few problems and Spy Sheriff told me I have loads more Trojan viruses that weren't there before as well as some that I thought had gone away. Is this anything to do with ClickSearchClick?
