Viruses are almost always brought on yourself.
I always eyeroll at my dad, when he tries to feign ignorance, "I swear, I only read El Pais - but I get SO many viruses!"
"Yeah, sure dad -.-"
"Maybe it's the girls! Yeah! They're all over strange and dangerous websites!"
"Yes, youtube and nrk.no*"
"Yes yes that's it!"
