Fake antivirus scams, which trick people into thinking they need to hand over their credit card info to update their antivirus, seem to be going away.

The antivirus vendor Kaspersky Lab said in a report that there are 10,000 fake antivirus attacks a day, down from 50,000 to 60,000 in June, according to an article Computerworld published Friday.

These scams work by infecting a computer with malware that pop up aggressive prompts to urge users to update their antivirus protection — even if the user already has up-to-date protection from a legitimate vendor. Some of the more aggressive versions of this scam even block access to the websites of legitimate vendors.

The decline in fake antivirus scams stems from law enforcement successes and improved search-engine filtering, among other factors, the article said.
