I had just done a fresh install of Windows 7 for my son (he wants to play with Lego Mindstorms) so the first thing I did was get Chrome on that laptop. I just opened IE, and typed Chrome in the search box (this is in the UK). I clicked the top ad which pointed me to
downloadlist.net/chrome. Unfortunately, I did not notice the URL at first. I just clicked and installed Chrome.
Next thing I know, I'm seeing a bunch of popups flash by, IE goes to some weird video site. I immediately open task manager and find 10+ programs being installed on the machine. Shiiiiiiiiit.
In any case, I've done a clean re-install but it might be worth for Google to get involved as your average windows user might associate this malware with Google.
