Spammers are hoping to rouse Obama critics to launch a cyber protest and to download malware onto their PCs in the process.

New spam is circulating that supposedly offers a way for people to use their computers to launch a denial-of-service attack on the Web site of President Obama, researchers said on Tuesday.

The e-mail message says: "If You dont like Obama come here, you can help to ddos his site with your installs."

The e-mail then provides a link to a Web site where visitors are offered money for installing the supposed denial-of-service (DoS) software, according to a blog posting on the site of e-mail security provider Proofpoint.
