I ran rkill to check of problems with my system XP/SP3. The file mqac.sys does no have a valid digital signature. I have 6 copies of this file on my system from past sp's. how do determine which one to use as a replacement? How do I check to see if it is signed, and if it is do I just swap them out?
Have already cleaned system, getting rid of old files, cleaning the registry, I.e. a deep cleaning to speed up my system and clear up problems. I have no malware or virus' that Avast and several other scan tools and detect.
