Be sure you have your virus programs up to date before going on that site full of cat photos. I went on yesterday and within a few minutes my computer was trying to download a program to "remove viruses". The program itself was a trojan trying to install. I had a hard time telling it not to install, keep giving warning after warning that i must install the "program" to remove a virus. After i got the install to stop i ran windows onecare and everything was ok.
Just a heads up.
