SpySweeper.exe 99 or 100 (High CPU Usage) - SOLVED. The "IE Favorties" shield was selected and I had too many entries in the "Favorites" folder. I created a new folder outside of the "Favorites" folder, moved the entries there. I then placed a shortcut to it back in the "Favorites" folder. This substantially cut down of the amount of time SpySweeper.exe was using the CPU when the computer was booting.
Part of WebRoot Spy Sweeter Suite. Utilizes CPU at nearly 100 % quite often. Hogs my disk access also. Not sure if this was happening before or not
Good spyware detection/removal program
Spyware monitor. I have also gotten false positives when it scans for key loggers. Otherwise safe.
good program but some spyware slips by
Probably the best spyware/adware/malware etc... removal tool around

Best practices for resolving SpySweeper issues

A clean and tidy computer is the key requirement for avoiding problems with SpySweeper. 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.

To help you analyze the SpySweeper.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
