You're mowst welcome, Feather. Yes, AVG 9 contains
> Basic antivirus and antispyware protection for Windows
and it's shutting off Defender, which is what it's supposed to do.
Windows Defender is automatically turned off during installation
http://www.avg.com/us-en/faq.num-2672#faq_2672
" During the installation of AVG 9.0 products, the Microsoft Windows
Defender application will be automatically turned off.
Windows Defender is not removed from the computer, only disabled for the
time AVG is installed.
Please note that this is important to prevent conflicts between AVG and
Windows Defender. As they are both security applications, they will try
to check files you are working with. Since they will do that at the same
time, conflicts may arise. These can cause freezing, crashes or slowdown
of computer. It is generally not recommend to use more than one security
product on one computer. "
Actually, one can use more than one security product on the same
computer BUT only *one* of should be actively monitoring the system
(aka RealTime Protection).
So, if you want to manually update Defender so it can be used to *scan*
the system IF a malware issue arises, you can get it's latest definiton
file from here:
