sysupdate.exe is a process belonging to an advertising program by EXact Advertising. This process monitors your browsing habits and distributes the data back to the author's servers for analysis.
Damage to your computer's registry could be compromising your PC's performance and causing system slow-downs and crashes too.
This also prompts advertising popups. This process is a security risk and should be removed from your system.
I strongly recommend that you run a antivurs software to identify and remove sysupdate.exe file.
