First impression
review by kenneth:

As above, it's a free anti virus software from microsoft corp.
for validated users of geniune microsoft windows os.
On the whole, it is a no frills anti virus solution which is
definitely on par with free antivirus solutions such as Avg, Avast
home, and i would rating scanning time as relatively fast, uses
little resources, easy to download (unlike avast) and quick to
install.
It's definitely a big improvement in over
it's predecessor windows live one care - a paid anti
virus software, which if one remembers, was a big unknown
(?) with people looking for anti virus software opting to pay
for a better and more well known anti virus such as Mcafee or
Norton.
That's said, it may not have the features like big shot anti
virus suites have, take for example, PC tuning up, Back up
features.
What is has is a simple to use interface, simple real time
protection that works - It monitors pc activity and
potentially unwanted software that presents it self trying to
install into the computer. Other features include Automatic
scans of flash drives and hard drives (if option is ticked),
Scans of archive files (.Cab, Rar, Zip)
Microsoft is also true to it's word that, the antivirus
software does indeed
" run quietly and efficiently in the background so that you
are free to use your Windows-based PC the way you want—without
interruptions or long computer wait times."

next edit-
Installation is quick - Quickly done in less 2 minutes.
Note: After installation, the intial quick scan would take
quite a few minutes to scan. This is normal and it does not reflect
on the scan speed of the anti virus. Subsquent ones are done in
quick time <45seconds
Side note
It's my 1st week using this, and my first and
honest impression of this product. I m not paid to do so,
and coincidentally, it's my first product evulation after a long
time. I might and might not be able to update this thread with more
interesting things I find after evulating the product. So feel free
to post what you find and I will try my best to add it in here to
share with everyone.
I would appreciate it if there were to be no flamers. Everyone
has their own perceptions and let's leave it that way. There's no
need to enforce your opinion that xx anti virus is the best and
this is not.
