It is AVG Antivirus and the error can be easily fixed by going to "Control", "Programs", "AVG Antivirus", "uninstall", then select "Repair Installation". Done! This applied to my 2014 free AVG installation.

avgui.exe may use a small amount of memory e.g 15,348k and at the same time occupy any and all free cpu space making your cpu useage constantly at 100% particularly in xp systems. one option is to upgrade your o/s the other is to remove avg and try another version or a reinstallation and if not thne use another application
