Repellent can solve your email and Internet virus worries with the click of a button, you can disable all VB and Java applets and scripting, as well as all Registry files. These are the viruses and worms that your virus scanner is trying to find and kill. Theset viruses do the real damage, like "Melissa", "KAK". A virus scanner can miss a new virus because it does not know the signature yet. Repellent simply disables the scripting capabilities.
