And yet I can only wonder why people don't properly protect their systems from hackers, crackers, viruses, trojans, etc, etc.
There's many good free firewalls and anti-virus softwares out there. Some webpage based virus checker is hardly enough.
A good firewall is Sygate Personal Firewall (standard version) and a good anti-virus is avast! 4 Home Edition.
And I agree with Admiral LSD. People are just utterly paranoid about everything. Which is plain stupid. Little paranoia does not hurt as it will make you avoid possibly malicious sites and such, but when you find yourselves checking your pants for possible gps trackers, you've got a problem.
