Users may encounter one of these malicious sites when searching Google for Halloween items.
Websense has described one instance of these scams as the classic " typo-attack" in which cyber-criminals create links to web pages that host malware.
The sites take advantage of commonly mistyped word searches such as 'halkoween' instead of 'halloween'.
These websites often advertise Halloween-related details in their titles, but actually contain dangerous spyware which could log user activity on the web.
