Manage Anti-Malware Software

1. For this part of the lab you will need an Internet connection for your laptop. Use a patch cord to connect your system to the ITC network jacks (the yellow jacks in B109) on your desk.
2. Windows 8 includes built-in anti-virus and anti-malware protection but older versions of Windows can be protected by third party software or the free Microsoft Security Essentials software.
3. Download and install a copy of the Microsoft Security Essentials software in your Windows 7 laptop.
4. Update the malware definitions to the latest version
5. Run a "quick scan" of your system
6. Sometimes a system is so compromised that anti-malware software running through the OS itself might be compromised as well and unable to detect or remove the malware. In these cases it's usually best to just format the computer and start with a fresh OS install but if you want to try and clean up the system your best option is to boot directly into an anti-malware program runnign from a CD or USB drive instead of into the OS itself and scan the system in "offline" mode. One such free program is the "Windows Defender Offline" software. Because this is offline it does not receive any updates after you download it so you would want to download a fresh copy each time you want to scan a system. It would also be the most secure to download the software and burn the CD or USB drive on a system known to be uninfected.
7. Visit the Windows Defender Offline site and read about the program
8. Download the Windows Defender Offline software onto your laptop and use it to create a bootable USB drive. Normally you would not want to do this on the machine you want to scan because if it is infected the infection could prevent the software from correctly operating but for demonstration purposes we'll build the bootable USB drive and scan the same system (your laptop).
9. Power down your laptop and put the bootable USB drive into your system
10. Restart your laptop and boot it from the USB drive to start the Windows Defender Offline software
11. Run a scan of your system using the Windows Defender Offline software
