Terrible idea. If you have a link or bootsector virus, you already may have loaded it and it's actively residing in your computer--potentially preventing you from detecting it or properly running your antivirus on your already infected system. You want to AVOID booting the hard drive of the infected system before scanning it with a CD or DVD (something read-only) based boot CD with an antivirus.
That's a GREAT one too! Kapersky has an excellent reputation for integrity, unlike Norton and McAfee (which I must STRESS to avoid).
