default-search.net

Hi, I’m using the free Avast anti virus which is not picking up on a problem that i have with Internet Explorer on windows 8.1. The home page keeps returning to default- search. net. I have changed my home page to Google. Next time I use it is back to default-search.net. Any advice /help would be appreciated.

Attach your basic logs. (MBAM, FRST and aswMBR…!!)
