Thanks guys.

I have WinZip and have used it for years. I just don't really care for its layout and such. I don't know what new versions are like, but WinZip 8.0 which I have is kind of clunky. I will give 7-Zip a try. I used it brifly a long time ago, but will look at it more seriously now.
Edit:
I downloaded and tried 7-Zip. I hope I'm not speaking too soon, but so far I love it! It has some neat features like actually being able to test the archive to see if it is corrupt. Oddly enough, what WinRar said was "corrupt" 7-Zip says is fine. Plus, my favorite feature of all - it's free! No more stupid pop-up every time I run it. I have since uninstalled WinZip and WinRar. I'm sticking with 7-Zip! Thanks again!
