I always patch my system and run regular scans with updated antivirus and antispyware scanners. But while researching this story, I got hit by a Trojan horse (Trojan.Winloginhook.Delf.A) that was too new for my antivirus program to catch. Whether it's a new variant on a familiar foe, like a Trojan horse, or a completely new type of attack, today's threats can leave even the most security conscious among us vulnerable.
