94.7 percent of Americans received at least one email containing a virus, spyware, or malware, according to Halon. About one in eleven (8.8%) opened the attachment and infected their computer.

Almost a third (30.2%) came dangerously close to doing the same, opening the email but stopping short of opening the attachment. These spam emails bogusly claim to come most often from banking institutions (15.9%), social media sites like Facebook or Twitter (15.2%), and online payment services (12.8%).

One in three Americans admit they would open an unsolicited email—even if it seems suspicious—depending on its subject line. For women, spam email messages containing invites from social networks are alluring, while men are tempted to open ones with the time-tested suggestions of money, power, and sex.
