I was downloading, This missing Shader for the Shader Pack: http://www.mediafire.com/download/wl37kh3e1xwye9c/#Building_Enhanced_v2.fx#Building_Enhanced_v2.fx From tutorial: Let’s start 3D-Moddeling for Cities XL Very Basic Tutorial by Mr.X² - Part I When I went to Mediafire to download, I picked up a browser highjacker virus. I downloaded this file once before with no trouble. Not sure what happened, but be careful with this download. So far, I have managed to get rid of it, with the exception of, I had to delete Google Chrome. I have everything back up now. I was a little upset so I don't remember the name of the file, but if this happens to you, you will know the name! To get rid of it, Go to your control panel, select uninstall a program, and uninstall it. Next go to your web browser, it's going to load it's own search engine page. When it does, go to another search engine. In IE, open the little gear Icon at the top right side of the page "Tools" and select "Manage Add-ons" Select "Search Providers" look to the right and you will see it there, mouse over it and delete if you can, or disable it. Now you will need to reboot your system. Google is about the same way, Go to tools on the top right. Scroll down to "More Tools", in the pop out, select "Extensions". Look for that extension and delete it if you can, or disable it. Reboot your system. I hope no one runs across this like I did. Good luck.
