Avast and Panda are both currently having significant bug problems. See reports on the net and on this forum (in other sections). Panda is bricking drives and Avast is eating up drive space.
MSE has a decent rep; not high on AV tests, but generally free of compatibility, resource, and bloat issues. Offhand, I can't recall anyone having a problem with it hogging the CPU, but you may have a legit complaint.
