Due to my Vista system losing the hard drive, I needed a new computer - yes, it is Windows 8.1. My question is what is suggested to keep it running in tip-top shape? It currently has a trial version of McAfee installed and I am not a fan. On my old system, I was using the free version of Avast! along with Malwarebytes, SpywareBlaster and a paid copy of TuneUp Utilities. Can anyone suggest if these should be installed on my new Windows 8/8.1 system or if I should try something else? I have not yet installed anything security/privacy related and am relying on the tools that came with the system.
