I just tried and I got this in both my laptops-

using IE I googled “stock market forum”

clicked on 3rd listing-
www.stockrants.com/forum/‎

and didnt get any message–

opened FF and did the same thing and both laptops gave me the same warning-

Infection Details
URL: http://www.stockrants.com/forum/misc.php
Process: C:\Program Files\Mozilla Firefox\firefox…
Infection: HTML:RedirDL-inf [Trj]

i guess I should note I can only do this 1st time after I restart the computer whereas the other message that says malicious URL blocked and redirects me does it everytime I click on the search link from searching " what kind of trojan is HTML:RedirDL-inf [Trj] "
