Start with an online scan from antivirus.housecall.com.
Then find, download and run adaware, spybot s&d and cwshredder. They won't harm, and they might find more stuff you don't like.
If these four tools don't find anything, or if you prefer the direct attack: see http://www.the-it-mercenary.com/forums/Help/posts/215.html
for a registry edit.
Simply don't click on it, if you don't want to see the site.
And note that one doesn't have to be particularly smart to find the above link using google. Otherwise I wouldn't have found it ;-).
no matter what webpage is up, if I right-click my mouse, there is an entry called "free pron galleries" I do not want it there. Obviously at some time during my surfing, that entry was put there. How do I get it to go away. I tried right clicking, so I could delete it, but the porn site comes up. regardless of left click or right click, the site comes up. Anybody smart enough to know how to get rid of the entry? thanks
