It is part of F-Secure and let's you update F-Secure. If you have F-Secure installed on your computer, this isn't dangerous. Charter also comes with F-Secure so if you get your internet from Charter this is also harmless. Otherwise this is a very dangerous application in disguise!
It is a part of the Charter High Speed Security Suite and should not be deleted from your startup as long as you use Charter Security suite.

It is definately to do with f-secure antivirus. It is an automatic updater for F-secure, so essential if you want to stay updated.
F-Secure's own spyware. That can spy your open programs and passwords. Actually smells like shit that whole F-Secure!

Best practices for resolving fspex issues

A clean and tidy computer is the key requirement for avoiding problems with fspex. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command.
