Using live connect you can bring up a connection to the machine that you want to operate (simply click on the icon next to the machine which needs a scan). This means that you can actually run an AV scan on the machine without bothering the user at all. Running a quick scan is super easy! You can run MSE from the command line. Now, once installed, lets say your user calls you up and says that their machine is not running well. We have several Securityessentials scripts available here. Security Essentials is included in Windows 8 by default as a module in Windows Defender, but in Vista and 7 it is super easy to deploy via a script we have written. Microsoft Security Essentials (now known as Windows Defender in Windows 8) is a pretty nice option as far as Anti-Virus goes if you need a simple solution. Perhaps you didn’t build it into your budget, or perhaps you’re looking for a lighter solution.
But sometimes, for whatever reason, you may not decide to be using the built in AV modules. There is also the anti-malware module (Malwarebytes). Kaseya offers (depending on which package you have with us) not one, but two powerful Anti-virus modules (Kaspersky or AVG).
