Avast and Malwarebytes detect nothing, does that mean clean?

I was wondering If avast and Malwarebytes both do not detect anything does that mean a system is clean or is there a chance something might have been missed by both?

You could try an online scan with Nod32 just to be sure.

It would help if you go to PROFILE then Modify Profile then Forum Profile Information then Signature: and put information about your system just like my signature about your system just like my signature so that the helpers can offer pertinent advice.

There is also a chance… But you will become paranoid if you think so ;D
