There are some good ideas here that may help me solve my little mystery. I used a spyware remover and found some suspicious things on my computer, but noting related to LookPortal. I forgot about F11 toggling fullscreen, so I'll have to try that if I get another LookPortal attack.

It may have been address-bar searches that took me to LookPortal - how can I change the search engine connected to my address bar? I looked through "Internet Options" in MSIE, but didn't find a search option.
