1st, just installed and ran SpyBot - it detected and destroyed mucho stuff that AdWare did not, and system performance greatly improved -- THANKS!
Now, about ShowBehind, which somehow got installed in /windows/sbnet directory on 11-14-02. I had been wondering why I was suddenly getting "popunder" ads, now I know, and SpyBot detected it and destroyed it (AdWare did not). However, since I do not open emails from unknown parties or those from known senders which contain attachments that were not specifically requested, I cannot understand how it got installed.
Can anyone elaborate on this program?
