Hey guys! Dosa here, and I want to know if the lineup I have is okay for defense against viruses when one uses good behavior while on the net. I have Avast Internet Security, MBAM Pro, and Sanboxie. Will this be enough? I just got a new computer that I will be using for college, and it cost me quite a sum of cash so I’d hate for anything to happen to it on both physical and internal ends. What do you guys think? 
IMO, you’re good to go.
Adding the creation of regular image backups to the mix insures the ability to restore your
system in the event of a catastrophic event.
I agree with everything mentioned above, but I would also install McShield if you use USB flash drives as extra protection. Keep your software up to date and have a good firewall, and you should be in good shape.
