This toolbar was installed with when I got an email address there. It installed in Internet Explorer so I let it install since I use Firefox BUT I noticed in Windows Task Manager (WTM) a program using a lot of memory called CToolbar.exe so I uninstalled's toolbar and guess what? No more CToolbar.exe in WTM. My guess is that is was monitoring everything I did on the Internet. It certainly used enough memory to do so and it was in IE 8 and I don't use IE8. I uninstalled it and good riddance.

Best practices for resolving CToolbar issues

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