Might not be a bad idea to buy a 2nd computer solely to store, watch and view your downloaded videos and photos, and other content of the sort. In other words, one not even hooked up to the internet. Because I don’t know what I’d do if my humongous collection of stuff was comprised like this.
We maintain three sets of MS Windows and Linux distro systems: online public network, offline private network, and standalones. Media are never shared between the online public network computers and the other computers. With one exception, the isolation has succeeded in keeping the offline computers and offline data secure.
The one exception was an HP Pavilion desktop computer. It was purchased to handle an urgent compatibility issue with some Adobe software. Microsoft at the time required this system to have access to the Internet and the Microsoft servers long enough to provide the critical updates and complete the initial setup of this brand new computer out of the box. The moment the Internet connection was established, a rootkit hijacked control of the computer away from the user, redirected the connection away from Microsoft’s automated update site, took the computer to a source of pornography that proceeded to flash an unending seried of pornagraphic images onscreen. A hard reset had to be used to shutdown the computer. This brand new computer was evidently somehow compromised before it came out of the box, because the user never had so much as one second of opportunity to do anything whatsoever to cause a malware infection.
