No Spyware Here!
It ain't us.
The only "pop-ups" on this site are in the U.S. Stamp Gallery, where clicking on a thumbnail picture will "pop open" a larger version. Your will never receive any "spyware" or hidden programs from VirtualStampClub.com.
However, clicking on an advertising link may put some "riders" on your system, but we try to make sure these are benign.
If your computer is behaving strangely, as if someone else were controlling it, we suggest you download and run Ad-Aware and Spybot S&D, both free programs (although for a few dollars, you can get versions with more features).
The links above will open in new windows, by the way.
