Lets talk Security and Optimizations

What antivirus, spyware, internet security, combo etc.. are you currently using?
Do you run regular maintenance on your machine? Defrag, Registry, temp files...

I was using Bitdefender Total Security, imo it sucked. I couldn't even access Texas.gov without disabling it. Also really slowed down https connections.
Currently looking for something new. Any recommendations?

I run TuneUp utilities to maintain a clean computer, it optimizes settings, defrags, etc.
