Just restore the location, if you haven't emptied the Recycle bin.

ANd I'm not wild about it anyway. Why pay when you can get as good or better protection for free? Keep in mind that everyone of these things is either free of charge or open source. The protection that you get from these is top notch. Furthermore, since I'm not recommending products that you have to buy (NONE of these will ever cost you a penny), you know that I'm not affiliated with the company or making money off recommending them, unlike some. The biggest benefit to you is that this also means that the updates are free. Running the software without the updates is the same as not running it at all. (It is precisely this reason that I don't endorse AVAST or AVG. You AVAST and AVG users can boo and hiss all you like. If you're not paying them, you're not getting the most current definitions, which means you're not fully protected. I don't endorse McAfee or Norton/Symantec because it simply shouldn't be possible for your antivirus software to become infected by a virus. That sort of defeats the purpose of having it.)
