I have noticed that there are two persistent spyware programs keep coming back over and again. I used Spy Sweeper. It seems to find these two then I delete them etc. but they keep coming back. i used then Adware 6.0 .. I used the Vx2 Plugin. I also was quite surprised to see that when I first used Adware.. it found like some 52 spyware entries of all sorts. Strange indeed since I that Spy Sweeper has been doing wonderful job all along. Now i am really skeptical of these so called spyware eliminaters. I bet if I use another program it will too find a few others. Anyway, my question is how to completely and permanently remove these two Twain-Tech and Vx2 spyware. And what spyware killer programs should I use to protect my computer. Thanks.
