You are operating your computer with multiple Anti-Virus programs running in memory at once:
AVG 7.5
McAfee
Anti-Virus programs take up an enormous amount of your computer's resources when they are actively scanning your computer. Having two Anti-Virus programs running at the same time can cause your computer to run very slow, become unstable and even crash.
If you choose to install more than one antivirus program on your computer, then only one of them should be active in memory at a time.
Please disable or uninstall one or the other so they do not conflict.
