Google Video Blog’s group accidentally sent a virus called W32/Kapser.A@mm — a mass mailing worm. Google Video Team said on the a message posted on the group.

On Tuesday evening, three posts were made to the Google Video Blog-group that should not have been posted. This has now been addressed and fixed.

Still, some of these posts may have contained a virus called W32/Kapser.A@mm — a mass mailing worm. If you think you have downloaded this virus from the group or an email message, we recommend you run your antivirus program to remove it. If you do not have an antivirus program, you can download Norton AntiVirus software for free from the Google pack, http://pack.google.com/intl/en/pack_installer.html?nopers

We’re sorry for any inconvenience, and we’re taking steps to ensure
that this doesn’t happen again.

Thankfully the risk of this worm is LOW to both home users and corporate users, according to McAfee. However, you will still need to clean it. If you have subscribed to the groups, and think your computer is infected, you can download free anti-virus software to do a scan, such as AVG, Avast!, and Norton from the Google Pack.
