So I installed a free version of WinZip here (http://www.winzip.com/win/en/index.htm). I received a warning from my computer that a trojan had been removed, so I uninstalled it. Now my homepage/new tab pages have been changed, and I don't know if I got a virus or something. All of the anti-virus on my computer need a new subscription, so can anyone prescribe a good, FREE anti-virus/have any knowledge of the site?
