Searches for news of the death of actor Patrick Swayze are likely to include malicious web pages that will trigger fake virus warnings, says security firm Sophos.
This comes just days after Symantec warned of an increase in themed cyber attacks, including phishing e-mails and fake websites associated with the FIFA World Cup.
Cybercriminals are using search engine optimisation (SEO) techniques to ensure that the malicious Patrick Swayze websites appear high up in search engine results.
Visitors to these sites will see fake virus warnings and links to bogus anti-virus software.
Once this malware is installed, users risk hackers stealing credit card details to commit fraud, said Graham Cluley, senior technology consultant at Sophos.
"The same tactic was used after the death of Natasha Richardson and the recent anniversary of the 9/11 terror attack," he said.
Cluley said businesses should ensure they are automatically scanning websites visited by all users on their networks.
"Businesses cannot trust that the search results users click on will not lead to malicious websites," he said.
