McAfee warns of scareware plague

Fake anti-virus scams extracting millions from unwary users.

Security firm McAfee has used its first Consumer Threat Alert to advise web users of the dangers of fake anti-virus scams.

Malware writers are increasingly using the technique to snare unwary users by presenting pop-up windows appearing to be a security report from a recognised firm.

The ads prompt the user to 'scan' their computer for viruses, but in fact often deliver malware designed to steal personal data and credit card information.

"It is an incredibly lucrative business for cyber criminals," said François Paget, senior virus research engineer at McAfee Avert Labs.

"In fact, one company known as Innovative Marketing made an estimated US$180m through these scams in one year, and more than four million consumers purchased their fake security software thinking it was real."

McAfee said that users should also be wary of free screensavers and other applications from non-trusted sources, and that it has seen a fourfold increase in the number of so-called 'scareware' incidents over the past year.

"Even the savviest of computer users falls victim to online threats because cyber criminals have become so sophisticated," said Jeff Green, senior vice president of McAfee Avert Labs.

"The Consumer Threat Alerts are a warning to keep consumers from falling victim to online dangers. We are on the front lines watching and protecting against threats, and we pass that knowledge on to consumers."

The firm has posted a video about the scams on its Consumer Threats blog, as well as a range of tricks to spot and ways of limiting the risk of attack.
