I’m not going to tell your kids what to do but…
I had one of my longest appointments ever today as I cleaned a computer free of almost 15,000 viruses, setup a network, installed a wireless card, removed bad security software and replaced it with AVG, did troubleshooting on a fax machine problem and installed Firefox.
I even left for lunch and to another appointment for a while. The appointment took 5 hours not counting virus scans (I went to lunch and another appointment once I saw that there were more than 500 viruses.)
Of course my client was curious how so many viruses got on the computer. I had to explain that it was all caused by infected files that were downloaded through a file sharing program.
