Hi, I just downloaded what I thought was a free zip software. However, when I downloaded it it was a very quick download. When I ran it, the window that popped up was more like a little html window (or small browser even) than an application. It had a bunch of softwares for sale in the window. At the bottom, there was a little window that says "Click here to download free zip software". When I did, a small window opened up, some text appeared, and then it automatically closed. Now my computer is slow. There's no zip software to be found anywhere in my programs list nor on my desktop! I am running Avira to see if it does anything. The other frustrating thing is that there is no program that was installed, so I can't even uninstall whatever was just put on my machine. Help.
