It looks like you have both Avast and McAfee installed on this computer. If this is the case you need to uninstall one of these. If you let me know which one you are going to uninstall I will provide you with a link to a website where you can download the appropriate uninstall tool.
IMPORTANT NOTE: Using more than one anti-virus program is not advisable. Why? The primary concern with doing so is due to Windows resource management and significant conflicts that can arise especially when they are running in real-time protection mode simultaneously. Even if one of them is disabled for use as a stand-alone on demand scanner, it can affect the other and cause conflicts. Anti-virus software components insert themselves deep into the operating systems core where they install kernel mode drivers that load at boot-up regardless of whether real-time protection is enabled or not. Thus, using multiple anti-virus solutions can result in kernel mode conflicts causing system instability, catastrophic crashes, slow performance and waste vital system resources. When actively running in the background while connected to the Internet, each anti-virus may try to update their definition databases at the same time. As the programs compete for resources required to download the necessary files this often can result in sluggish system performance or unresponsive behavior.
