Hello, I am informing you people about a free program that makes you
tension free through checking processes in your system comparing their
signatures
continuously with a signature file that you have generated first. It
will alert whenever they change and when a new program runs.
This is meant for knowledgeable people. Download it only if you know
what you are doing.
Thanks.
