Content Filtering is a feature in the PSB portal located within theBrowsing Protection tab. Content Filtering allows you to block web contentbased on the file type; for example, .swf, .jar, .exe.
The feature works as a safeguard in conjunction with a Security Cloudlook-up of the domain/URL. While the F-Secure Security Cloud has ratings for avast number of websites, new sites are coming all the time. In case there is norating for a site yet, this functionality can help protect you by blocking filetypes according to the Content Type Filtering table in the PSB portal.
In practice, if the Security Cloud deems the domain/URL safe, thedownload is not blocked. However, if the Security Cloud deems the domain/URLunsafe, access is blocked, regardless of the file types selected in ContentFiltering.
