Hewlett-Packard will bundle antispam software with its latest desktop PCs.
The company will preload interMute's SpamSubtract Pro product on HP Pavilion and Compaq Presario PCs.
Customers who purchase the PCs will be able to use the spam blocking software free for 30 days with the option to purchase a full licence for the software for $29.95 (£17.90) from the interMute website.

SpamSubtract Pro acts like a spam firewall, using a specialised algorithm and database of spam e-mail identifiers such as obscene words and offensive images, as well as commercial solicitations.
Incoming e-mail messages will be sorted into folders for confirmed spam, suspected spam and "friendly" messages.
The product is also capable of masking offensive words in spam e-mail messages and preventing image attachments from being previewed, interMute said.
Customers who do not purchase a licence will continue to be able to use the product to quarantine spam with obscene words and images. However, commercial solicitations would no longer be flagged.
While bundling software on PCs is a common practice, HP was interested in having some of the "family friendly" antispam features stay on even for customers who do not choose to purchase a SpamSubtract licence, he said.
SpamSubtract runs on the Microsoft Windows platform and works with common e-mail clients such as Outlook, Outlook Express and Eudora, interMute said.
