What does encryption do for me?
Encryption and cryptographic software has been used in many different ways to make systems more secure. This article discusses only a few ways that such software can make your system more secure, including:

I recently hit, by mistake, what I thought was an Explorer upgrade option. It turned out to be a pop-up appearing legitimate but really was not. It uploaded a product called Intelligent Explorer on my machine. What a nightmare!
I did some research on the web and found messages like this one from a BullGuard Antivirus Forum,
“PLEASE HELP!!! I HAVE A SPYWARE, TROJAN AND HIJACKER ON MY COMPUTER. I HAVE RUN BULLGUARD, CWSHREDDER AND AD-AWARE. ALL HAVE PICKED UP THE VIRUSES AND SAID THAT THEY HAVE BEEN MOVED/REMOVED BUT WHEN I LOG ONTO THE INTERNET THAT DAMN INTELLIGENT EXPLORER TOOLBAR IS SHOWING”
Another message from spywareinfo Forum goes something like this:
“Hey I’m having issues with something called Internet explorer toolbar – Intelligent explorer. I can’t find a way to remove it from my comp and I really don’t want to reinstall windows. I’ve used spybot, ad-ware, and cw shredder but nothing seems to work.”
