Microsoft Security Essentials implements a shell extension for scanning custom files, folders or drives when exploring the computer. The real-time guard can be disabled from the Settings panel. The interface is incredibly easy for novices to figure out. Resources usage is generally low when the real-time layer is activated and no scans are running.
The notification system is intrusive. Too many messages keep popping up from the bottom-right corner of the screen when no actions need to be taken
. During tests, confirmation for cleaning the same threats was often requested by Security Essentials.
When the tool is applying selected actions on infections, you cannot cancel the task, navigate MSE's interface or minimize the window. The progress bar in the “Potential threat details” panel
is frequently misleading when removing or quarantining files, aside from the fact that the job takes too long. It starts filling the meter rapidly and progressively decreases in speed.
The History tab does not include reports for each scan job, nor total scan time. Furthermore, it is not possible to schedule custom scans or definition updates, look for only particular file types, or specify the default action for real-time protection and scan methods individually.
The bottom line is that MSE is a suitable security solution only for casual users
who don't venture too often in the Internet's darkest corners. More advanced (or courageous) people will need to take the next rational step: upgrading to a more powerful product
