Yesterday, I received a tweet update telling me, there's a new Microsoft freeware that just came out from Beta stage. I was excited then. Microsoft Security Essentials 1.0 is ready to be used.
It is the first free antivirus product with malware scanning that is from Microsoft.
The best information about Microsoft Security Essentials can be read from this wiki.
Its has only been 1+ days since I used MSE. There has been mixed feelings. First thing in mind is that "How does this MSE fare as compared to commercial AV products from Symantec, Mcafee and others? Is there a formal rating to back this product?"
Performance
I am not going to uninstall it just yet because of this isolated case. It does have a performance impact due to a doubled antivirus concurrent usage now.
This product has potential in the future of Windows to come. I believe all these can be ironed out to gain back the confidence in the Windows Community.
If this product is to be made a corporate essential instead of 3rd party antivirus softwares, the benefits it brings will be great. I hope Microsoft Security Essential will be able to score high in the commercial ratings if they test it.

Performance
- Significant performance drop in zipped file extraction, viewing of folders with many compressed folders which can cost 100% cpu load for a short while.
- Quick Scan and Full Scan can have adverse effects on the system. I will discuss this in a while.
- Scheduled Scan when Computer Not in Use not effective
- Realtime Protection behaves quite well most of the time, nearly negligible cpu load when there is no disk activity or application launching.
- MSE Scheduled Full Scan was halted after 2hr 20mins, i believe it was still in the midst of scanning the cabs in the Windows Directory
- Taskmgr refused to open during the execution of the scan
- Paint.NET hung around 3 times (eventually ended via taskkill.exe) when trying to load the File->Acquire menu
- Microsoft Excel 2003 hung around 6 times when trying to scroll the page using the mouse (eventually ended via taskkill.exe)
- Firefox is in use for nearly 8 hrs of continously without closing the browser once. It was closed normally but refused to open again.
- I have to say that this HP system is booted up while I was testing its quick launch buttons. Normally Quick Launch Buttons should not boot up a system. It may have some form of effects on the session.
- The system is unable to be rebooted via Start Menu
- System hung when trying to come out of Windows Security Dialog (Ctrl+Alt+Del)
- The system HDD LED is still flashing periodically when it crashed.
- The power button was finally pressed to force the shutdown.
