Search.mpc.am problem on firefox

[breaker9320]

So this search.mpc.am started making itself my homepage. I tried putting google back on but even so it will just show that one instead. Even tho if I check the options it says that google is my homepage. Tried resseting firefox. Did not work. Removed all my extensions still did nothing. I cant seem to find any program in my computer that should not be there. Nothing suspect..help please.
Eversince this happened my Eset antivirus started telling me it finds infected files and no matter how many times it says it cleaned it, it keeps finding another and another..
