Fred, your post gave me an Idea, maybe.
One can go to
http://www.virtualbox.org and download for free virtual machine software. It installs easily on most any PC. It allows one to create "Virtual Machines" inside your existing PC.
So, create a virtual machine. and load windows in it. An old copy of XP is just fine. No need roe a virus checker or much of anything. As soon as it's loaded take a snapshot of the freshly loaded blank machine.
Now! If you get a link or an e-Mail with a questionable file, open it in the virtual machine. If it does something evil, shut down the virtual machine, no harm done. Next time you start it, load from the snap and Voila! all the damage is gone and you have a pristine VM again.
Anyone with more VM experience than me see anything wrong with this? I use them, I am not a guru.
