I went for the "free scan" to see what was going on with my computer. I expected it would take forever to look through all of those files on my computer, but it didn't - it zoomed right through them and picked up things on my computer that evidently hadn't been found by the AV program that was on my computer. It prompted me to purchase the full version so it could clean up my system. Since AVg didn't find them, I figured it couldn't fix them either, so I got the package. I feel more confident this software will keep me covered so I don't get these things again.
