According to the Google study: “surprisingly, many users fall victim to these attacks and pay to register the fake anti-virus software.” These programs often succeed in duping PC users because they use scare tactics. Those that don’t have anti virus protection probably already know that they ought to. Seeing a message, especially if it looks like it comes from a trusted source, may prompt many to take action because they panic and see an immediate fix in front of them.
Malware problems seem to be on the rise in general. For example, a recent Symantec report showed a 71% increase in malicious software and also noted a rise in fake anti virus problems. As is often the case with computer security, preventing problems from occurring is a lot easier than dealing with them after the event.
Users may therefore want to take some time to learn more about fake anti virus and scareware scams to avoid getting into difficulties. Those without anti virus protection may find it useful to put a reputable program in place. Many of the major suppliers in this sector offer free trials and free versions that will give basic protection if cost is an issue.
