Spyware Most Prevalent Through Adware

ActiveScan, the online solution from PandaLabs has detected adware in nearly 64 percent of spyware in January 2007. spyware found today has three sub-categories: spyware itself, Adware and PUPs (Potentially Unwanted Programs).

The adware category of spyware displays advertising banners while the program runs on the system.
