Thanks for your help Tthurman. Luckily i got it sorted and have most of my emus working. I forgot to copy 'gameex.ini' -file from my original installation. Thought i did it but apparently not. Too much of staring the screen for one day i guess. Have to reinstall some emus but not too many. I thought i had to start from scratch and set up everything all over again, which would have been a nervewrecking process, but thank god not. I only wiped windows partition. Everything else is on a separate partition, so the directory structure for my emus and roms remained the same. My browsers were unusable because all these nice little ads kept popping up and something was messing with my internet connection. Tried ccleaner, spybot, malwarebytes something, jre, avast...Some of it was removed, but it kept coming back. Tried manually remove startup junk in 'msconfig' and rebooted and there was couple new random programs every time. Normal and safe mode. Sometimes it's easier to just wipe and do a clean install. Hope it will stay clean for some time. I'm not going to use my arcade cabinet for browsing anymore.
