here is another program I have added to my arsenal of protective devices...System Safety Monitor
(note..although the program is fine & safe, this page is in Russia and tries to set a bunch of cookies, including some which are not related to the domain...be prepared)

"System Safety Monitor (SSM) is an application-firewalling tool (it is not a "firewall" in traditional understanding, so there shouldn't be any conflicts with your network firewalls). SSM controls which programs are running on your computer and what they are doing. For example, SSM can prevent so called "DLL Injection". Also, SSM will notify you whenever a program you want to start was modified. In addition, SSM can constantly check your registry and alert you, when an important modification was made."
