I use PE Guard since its first release and I only can say that it's absolutely amazing !! It's very effective, easy to use and extremely light on resources.
And now the newest version, PE Guard2.1, has become even more powerful making it a top-option for protection software. I can't imagine using anything else :D !!
Opaida, thank you so much for being so creative. You are simply the BEST.
GOD bless you.

Thanks a lot, Opaida, for the update !
The -shutdown bug- is fixed...
This is a must try and it will probably become a must have !

you are right frank, the program was buggy in some error cases!!
anyway, now it is better.

This is crap. every time you restart your computer, the software stalls, it states that you should contact opaida. DO NOT WASTE YOUR TIME WITH THIS SOFTWARE

this is the perfect disk shield free and light bravo Opaida

Many thanks for the developer Opaida !!
This seems to be a very important program.
After installing it, I really feel that my PC is now more safer than ever !!
I recommend everybody to try it out, because just like this program assures: say bye bye to viruses ^_^
