Businesses may be at risk of virus infection if employees use the web to search for information on a Facebook application.

Rumours that a Facebook application, known as the Fan Check, is malicious are prompting Facebook users to search for information.

But search results link to malware, according to security firm Sophos.

Clicking on the malicious links launches scareware that warns of a number of threats on the user's computer that can be removed by clicking another link.

This link then installs malicious software on the user's computer.

"Malware is not just a consumer problem. It can have a real impact on business computers," says Graham Cluley, senior technology consultant at Sophos.

Once a hacker has control over an employee's computer, they could potentially steal sensitive data, use it to send spam, or launch denial of service attacks, he said.

"Businesses should ensure they are scanning website visits by staff automatically in the background as search results could easily lead to malware," said Cluley.
