[comp.virus] Is this worth $75?

Someone told me that his product:
1. COMPLETELY protects against invasion of operating system viruses;
2. Prevents the spread of file viruses on hard or floppy disks; and
3. Searches out and suppresses file viruses.
How much protection does this give? Is it worth $75?
Thanks for any answers/comments.
