Just a few short years ago, all a PC needed for protection was a basic antivirus program to guard against any malware that arrived via an e-mail attachment, embedded in a shareware application or piggy-backed on a floppy disk.
These days, however, the threat landscape has changed drastically. Now PC users have to cope not only with viruses, but also with spyware, spam, infected Web sites, adware, key loggers, phishing schemes and much, much more. It's enough to make your head spin.
