As you swim in the sea of www / email,
please recognize there's a stealthy, dense population of semi-intelligent HOSTILES (newly-nefarious ones are born about one per every 15 minutes 24 / 7, each persisting in the environment for a few YEARS)
They're intent on harming you, YES, YOU!!!!
Visual:
Imagine "The Matrix" movies, which depicted an endless avalanche of evil murderous metallic bots seeking to swarm the ship (the Ark) of Neo and Trinity.
THe Ark is YOU and YOUR bank/credit/school/amazon.com/facebook/optionsXpress/Scottrade/ticketmaster / Homedepot.com.Costco.com/ etc. etc. accounts.
YOU are freash meat TO BE HARVESTED for anything & everything they can get out of you - if not your account info then instead your browsing history.
The only part of you they throw away is your squeal.
When you deal with computer Security, GO BIG. GO REALLY EXPENSIVE. BUY THE ABSOLUTE TOP ULTIMATE BEST. IT'S WORTH IT!!!
Otherwise, probably you too will join my club. I've received letters of apologies from a major top 10 university, a FIdelity finance organization, 2 famous stock brokerages, and a couple of retailers, pleading "oh we're so soorrrrryyyyyy despite our state-of-art firewalls they got in and took your name, dob, social security number, mother's maiden name, credit card numbers and security codes on the back, your bank account numbers, login IDs and passwords, WE'RE JUST SO FRIGGIN SORRY (tough luck for you) and now we get a big fat BONUS that YOU fund!!! !!!
Get the absolute best security you can, whether that's simply a good internet security suite, or maybe also a top flight sandbox or other...DON'T SCRIMP in this area.
