Microsoft Security Essentials

Doesn’t get in the way of PC performance

As a Information Security professional, I often get this question: Which is the good anti-virus? Which one i should use?

Here is my pick out of the bunch of anti-viruses software available in the market.

Microsoft Security Essentials doesn’t carry the weight of suite products and has a much smaller download size. Scans and updates are scheduled to run when the PC is idle and use a low-priority thread. CPU throttling ensures that no more than 50 percent of the CPU is utilized by Microsoft Security Essentials activity, so that your system continues to perform those tasks you are likely to be performing, such as opening files or browser windows, saving files, and using cut, copy, and paste.

Microsoft Security Essentials uses smart caching and active memory swapping so signatures that are not in use are not taking up space, thus limiting the amount of memory used even as the volume of known malware continues to increase. This makes Microsoft Security Essentials friendlier toward older PCs, as well as today’s smaller, less powerful form factors such as netbooks.
