I'm always envious of those who have never had to worry about trojans and other forms of malware - but having had to too many encounters and then working for an IPS, followed by medium size global company in the IT Support team, I realised it is not a nice place out there in the ether and try to keep a safe place from it.
I should point out that I do use a fire wall and anti-virus software and always have. I still believe most viruses are downloaded in free software or opening emails from sources you don't know or recognised.
The issue with beta testing wifi required the closing down of all firewalls and anti virus. This was beta testing and very much the early days and it was as much as they coould do to get the system to hook up, let alone persuade firewalls and anti virus to accept them. Once connected, switched on firewalls and anti virus to teach them to work with anti virus.
And there, maybe, is the clue to why I've seen so many more of them than some of you. My internet activities required me to work with analysing and managing the risk of virus's and hackers. I was beta testing wifi when most people hadn't even heard of, let alone signed up for, broadband with a 512k bandwidth. At that point, most people did not understand the concept of viruses let alone virus checkers. Worse still, very few actually had, let alone an upto date, virus checker.
It's 22 years since i first accessed the internet along side bulletin boards.I've learned a lot since, and prices have tumble from £300-400 pcm to just £25pcm for amazing internet content. But sadly, the ill wishes of others seems to have grow to match...
