Recently i have noticed when browsing a web page will be redirected to something other than what i click on. For instance, when i tried going to www.askubuntu.com via a link on ubuntu.com it redirected me to some other site than this one.
Also when on a page with no flash videos of any kind or pop up windows an ad will start playing. The only way to get it to stop is to wait for it to finish or close the browser and start over again. I have run Clam AV but it has not found anything.
