My laptop used to have Microsoft Security Essentials, until it was announced that it would stop working in April, so I searched for a replacement, and came up with Bitdefender, and it seems to be a pretty good program, and it's done the job so far.
As for my cell phone and tablet-- both have AVG and Lookout Anti-virus, and it's because I want to be able to catch whoever is trying to gain access to my phone or tablet to be photographed, and I'll know who it was.
