All these protection programs are the viruses and troublemakers.
I have not had any virus protection in 7-8 years and have zero problems.
Stay away from porn, Russian or German sites and you will rarely be exposed to viruses.
Also, though new, you may have somewhat incompatible parts in your new computer as atrange as that sounds.
Plus HP is considered a bad computer product by most people. Stick with a cheap Lenovo, they work!
One should also stay away from Russian or German hookers. They too can give you a virus. :)
