AVG AntiVirus is a free and popular antivirus application that people have been using on their desktop computers for years to protect their desktop operating system, such as Windows XP or Windows 7. Did you know that AVG also has an Anti-Theft Service for Android devices? Here’s how it works.
So what about security and does this Anti-Theft service really work? In my tests, I found that the application works for the most part and can be useful to lock a stolen device remotely (and potentially wipe out the device, which I didn’t try). The features work, except that the first time I used the Locate feature, it didn’t even come close to the actual location of the device. While my smart phone was in my had, it showed that my device was located in a different zip code about 10 miles away from me. After a while it did show the exact location, so decide for yourself if this is good, bad, or ugly.
Another weak point that I discovered is that the application itself doesn’t use Secure Socket Layer (SSL) to encrypt the pages on the Web site. This surprised me. A company that makes AntiVirus software should be securing pages where customers are entering passwords and working on Anti-Theft software. In other words, you are using AVG’s unsecure page to secure your Android device. Really? This makes no sense.
Not only the Web site is unsecure, the password that you provide to lock the device can only be 4-6 characters. In other words, the password you provide is going to be very weak. While this may be good enough to keep an average “Joe” out, it won’t be good enough to keep a serious hacker out.
Hopefully, over time AVG will improve this application. It’s a good start but in my opinion the application appears to be more for fun and games than to offer a serious anti-theft service……mainly due to the quality of service and the fact that AVG doesn’t offer encryption to use a security software on their Web site. As I mentioned already, it does seem to get the job done for the most part so I am not ruling it out as a totally useless application. I believe it needs work to offer better reliability for locating the device and also needs some security improvements. After all it is a security application.
You can manage multiple Remote Desktop Connections with RDCMan, a utility that has been around for a long time. Unfortunately, Microsoft didn’t make this tool widely available for several years. Fortunately, Microsoft’s Symon Perriman pointed out during his presentation at my Seattle Windows Networking User Group a couple of days ago that a new version is available from Microsoft. It’s version 2.2 that was posted on 5/27/10.
RDCMan manages multiple remote desktop connections. It is useful for managing server labs where you need regular access to each machine such as automated checkin systems and data centers. It is similar to the built-in MMC Remote Desktops snap-in, but more flexible.
Supported Operating Systems: Windows 7, Windows Server 2003, Windows Server 2008, Windows Server 2008 R2, Windows Vista
Users using Windows XP or Windows Server 2003 will need to obtain version 6 or newer of the Remote Desktop Connection client software.
You can download RDCMan here.
Telnet Client is not installed by default on Windows 7, Windows Server 2008 R2, Windows Vista, or Windows Server 2008. The procedures to install Telnet Client vary based on the operating system you are using. Microsoft has documented the following instructions on TechNet in this article.
To install Telnet Client by using a command line.
Managing your workstations and servers remotely has become a necessity these days. Here’s a comparison of remote desktop software on wikipedia that you may find helpful.

The Shutdown command can be used to remotely restart or shutdown a Windows 2000 or later computer.
For example, you can remotely reboot a Windows 7 computer from a Windows XP computer as long as you have administrative privileges. On the destination computer, you may need to ensure that your account has the user right “Force shutdown from a remote system.” You can run gpedit.msc at the Start, Run and then add your account to that user right, as shown in the screenshot below.
The shutdown is especially handy for Network Administrators and PC Support professionals in a domain environment. Here’s the syntax used by the shutdown utility.
C:\> shutdown /?
Usage: shutdown [-i | -l | -s | -r | -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]
No args Display this message (same as -?)
-i Display GUI interface, must be the first option
-l Log off (cannot be used with -m option)
-s Shutdown the computer
-r Shutdown and restart the computer
-a Abort a system shutdown
-m \\computername Remote computer to shutdown/restart/abort
-t xx Set timeout for shutdown to xx seconds
-c “comment” Shutdown comment (maximum of 127 characters)
-f Forces running applications to close without warning
-d [u][p]:xx:yy The reason code for the shutdown
u is the user code
p is a planned shutdown code
xx is the major reason code (positive integer less than 256)
yy is the minor reason code (positive integer less than 65536)
To restart a computer make sure you use -r, to shutdown the computer use -s. As mentioned earlier, the shutdown command can be used on a local or a remote computer. To restart a remote computer use -m \\computername. For example, if you have a computer that’s hung on a certain process and you can’t even remote desktop into it, you can try to restart the computer remotely and force running applications to close without warning by using the following command.
shutdown -m \\computername -r -f
If you want to use the GUI version, simply type shutdown -i to bring up the graphical interface. Here you can add, one or more computers, configure the option to Restart, Shutdown, or Loggoff, display a warning notice on the computer, configure the computer to reboot after a specific interval, and configure the option for Shutdown Event Tracker that will record the reason for the action in the Event Viewer.
I mentioned at the beginning of the article that you can use Shutdown utility on Windows 2000 and later computers. Microsoft’s KB article 317371 explains how to use Shutdown tool in Windows 2000. However, notice that the older utility used a forward slash (/) instead of a hyphen (-) for the switches.
