trouble with Win 8 and Malwarebytes

I thought I have kept this clean but Malwarebytes is cathing over a hundred files it considers not safe. I have not gone to 8.1, have a few pics from Reddit, Ventrilo, Lotro, Chrome, defraggler (not used yet), CCleaner and Norton Security downloaded from comcast. I keep this clean, There have been a couple on this besides me that went to Wiki and Facebook and I think that is about it.

I am not sure if the Alienware has the dell factory restore but I kept this clean just for this reason. I only play lotro now but that is only because MMO’s suck at the moment. I bought this for gaming…mmo, maybe a new CIV, something new, hell it was 5 years old. Has anyone had problems with this? I found a few files that looked like trojans and got rid of them but the rest seem to be in the registry. Should I just give it a go and restore if it goes bad?
