While this isn't the exact program that you're talking about, I found a guide from the Bleeping Computer website on how to remove the "Security Essentials 2010" virus, which you can view at the link below.
Also, if you are unable to download or run any programs because of this virus, I would suggest that you try booting your computer into Safe Mode with Networking, which you can do by restarting your computer and then repeatedly pressing F8 while it's booting up. From there, a menu should appear with a few boot options, including Safe Mode and Safe Mode with Networking. You can select Safe Mode with Networking by using the arrow keys and then pressing the "Enter" key in order to select your choice.
Once you've booted your computer into Safe Mode with Networking, you may be able to download and run programs, including Microsoft Security Essentials, as Safe Mode with Networking only boots with the essential drivers for your computer to run and access your network and then Internet.
In addition to running an antivirus scan with Microsoft Security Essentials, I would also suggest that you run an antispyware or antimalware scan.
If you need a free antimalware program, I would recommend that you try using MalwareBytes, which can be downloaded from the link below.
Once you've ran both of these scans, you should boot your computer back into "regular mode", which you can do by simply restarting it, in order to see if you have successfully removed the "Internet Security Essentials" virus.
Good luck and please let us know what happens!
