Once you've installed an anti spyware application, most people assume
that they're fairly safe. Unfortunately, even with the very latest anti
spyware applications, you can't always be sure. As with other
anti-virus applications, much of the security is provided by systematic
checks, updates and so on. If your out of the office or away from your
computer, you can't always ensure you run system checks and this makes
it possible for a Trojan or other malicious software to access your
system. 30 Jul 2009
