I apparently have one or more viruses in my XP computer that is blocking access to anti-virus we sites and is messing with my browser. When I do a search (either Google or Live Search) the results appear but when I click on a hyperlink I am redirected to an ad site that has some relation to the search terms. Worst of all, very often when I type a URL for an antivirus web site in the browser window, it gets redirected as a Google search and I can't connect to the URL, or I get the message "Internet Explorer cannot display the web page." For example, when I enter http://www.bleepingcomputer.com
I get the message that "Internet Explorer cannot display the web page." However, when I click on Diagnose the Connection, Windows reports that the internet connection is fine. Most other (non-antivirus) destinations appear to be immune to this redirection - I can connect to them.
In order to be able to access HijackThis I had to download the program on another computer (that is not infected) and transfer the program to my computer and run it. Then when I run HijackThis the log is prepared, but when I click on "Upload to TrendMicro" I get the error message in my browser, "Internet Explorer cannot display the web page." So I e-mailed the log to the computer I'm using to post this message and I will attach it from this computer.
I have scanned my computer using AVAST and Threatfire, but they have not solved the problem.
Thanks for any help you can provide.
P.S. - Using Foxfire instead of IE produces the same behavior
