What specifically would you like to know about security models for computer systems?

If you provide some more information, other users would be better able to assist you with your question.

Are you asking about which programs one should have on their computer in order to keep it safe and free of viruses and other malicious files and programs?

If you need a free antivirus program, I would suggest that you try using Microsoft Security Essentials, which was created by Microsoft, and can be downloaded from the link below.

In addition to running frequent antivirus scans, I would also suggest that you run frequent antispyware or antimalware scans.

If you need a free antimalware program, I would recommend that you try using MalwareBytes, which can be downloaded from the link below.

Just so you know, if you have more than one antivirus program installed on your computer at the same time, they may end up conflicting with each other, causing false-positives and potentially other issues.

Because of this, if you would like to try using a different antivirus program, such as MSE, you should first uninstall your current antivirus program.

However, it is alright to have both an antivirus program, as well as an antispyware or antimalware program installed on your computer at the same time, without any issues.

Additionally, perhaps you should try using either Mozilla FireFox or Google Chrome, both of which are safer than Internet Explorer and can both be customized with a variety of add-ons and themes. If you'd like to try using either of these browsers, you can download them from the links below.

Best of luck and I hope I helped you!
