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

Best practices for resolving avgui issues

A clean and tidy computer is the key requirement for avoiding problems with avgui. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
