Modern malware apps curl up and make themselves at home in your system, where they wait for a chance to snatch an important password or a credit card number. Welcome to the era of capitalist hacking. Any self-respecting malware program today is polymorphic, making signature-based antivirus approaches difficult. Heuristics and virtual sandboxes offer alternatives, but all such methods are reactive. Unfortunately, monitoring lists and networks is about the only current alternative."
