I had terrible problems a couple weeks ago. Started with redirects to various sites. Then popups. Just here with chrome as my browser. Then after about a week of minor annoyance the problem went nuclear. I could not browse the web. Any site instant full screen coverage of popups.

Cleaned everything out. Found a addon linked to chrome that I could not disable or delete.. Uninstalled chrome and reinstalled. Came back here instant problems. Addon was back. Again uninstalled chrome and reinstalled. Three days of problem free browsing. Came here instantly hit again. Tried three times everything good til I came here. Got rid of chrome been running IE with no troubles.
