 SEATTLE (Reuters) - Microsoft Corp. warned about a new computer virus that
exploits a vulnerability in its PowerPoint presentation software to allow
hackers to infiltrate computer systems. Microsoft issued an advisory on the
company's security Web log on July 17 about the virus, which is carried out
when a user launches a PowerPoint attachment to an e-mail or opens a file
provided to them by the attacker.

Hackers could also lure users to a Web page that offers content or
advertisements containing a file that exploits the PowerPoint software,
Microsoft said. The vulnerability applies to PowerPoint 2000, 2002 and
2003.

Once the user triggers the corrupt PowerPoint file, the virus installs a
keystroke logging system to capture everything typed on the machine. It
also leaves the machine open to having a hacker install other malicious
programs.
