Re: Malicious Software Tool - is it worth it?

Yes, I would recommend that you allow its use.
There is a very large amount of research behind the monthly
MRT releases that takes into account what is being seen in
the wild. The MRT also addresses some things your standard
AV may not. It is a one-time execution and does not interfere
with your existing anti-malware.

Is there a trick to running it once you've downloaded it?
