The virus is called our surfing. I have done things such as uninstalling programmes, changing home page and search engine URL, refreshed Firefox, removed suspicious toolbars and extensions and ran HitmanPro and CloudSystem. All that remains is that everytime
I restart the computer, an additional new tab of our surfing will be displayed. If I close Firefox, it would not appear, only upon restart. I have deleted about:config which have the term oursurfing and removed cpuminer from task manager. But are there other
services in task manager and settings in about:config that I should know about? Is there the ultimate solution to rid of this virus?
P.S. I also tried the "prefs.js" method, but I could not find the "browser.newtab.url" preference at all.
