I have a Toshiba laptop, model #L305D with windows 7. Several days ago, I noticed that whenever I open my browser (I use firefox) I see a blank page with the url http://www.inlinesearch.com I still get the same page whether I open the home page or if I open the last session used.
I've done scans with my anti-virus (avast), spybot & malware bytes. Those programs have found some issues but they still haven't had an effect on this issue!
Can someone help me figure out what's going on? If you need more info, I will be happy to provide it.
Thank you.
