Hello. Do you all use different security setups on your various machines out of worry that if you have the same setup, then something can go wrong (malware, software malfunction) that will kill all your machines? For example, at the moment I have two Windows-based computers, a desktop and a laptop. I am running a version of F-Secure Internet Security on one and Avira Antivirus Pro on the other other. I have two lifetime MalwareBytes Pro subscriptions that I am only running on demand at the moment. I really like the F-Secure product and I get it free from my my Internet service provider, but I am hesitant to run it on both machines. I am a safe surfer and really don't expect to have any trouble, but I have a slight worry that if something goes wrong with a product that I am running on both machines, then I will be totally knocked off line for some period of time. Does anyone else think this way or am I worried about something that is a non-issue? I have been known to worry about non-issues before. I hate to keep paying for software if I can get something good like F-Secure but so far the above worry has kept me buying licenses for other quality products. Also, my F-Secure is a branded version Charter Communications. It does seem to be the 2015 edition but some of the modules seem to be slightly behind the very latest ones in the product that you download directly from F-Secure.
