XP Security 2011/2012, and more

[suesloan]

After running Spybot and thinking this "thing" was handled, I rebooted and after Spybot did another scan on startup, I ran StopZilla and it found about 30 viruses and trojans and lots of adware cookies.

I had previously run MalWareBytes and thought the machine was clean but not so.

I have Avast running and it has been stopping access to various sites, but one problem remains. When I click on a link in a google search result, I usually end up on the wrong target site. Like this one: http://r.looksmart.com/.... or this one: http://c3055882.r82.cf0.rackcdn.com/amp_ra_landing_cdn.html

What can I do to stop this? Note this is happening in IE and Firefox browsers.
