Think i might be infected

H, I have done scans on norton and malwarebytes and Trendmicro housecall and also adwcleaner and roguekiller. All have gotten rid of stuff etc but my computer didn't start normally earlier today and also in norton recent history  have been getting alerts like unauthorized access blocked (open file) and unauthorized access blocked (access process data). Also norton allowed something called WGET to access my network resources. What s going on? I'm getting sick with worry.
