If you can reinstall (i.e., you have got their licenses and their installer) Cisco AnyConnect, speedvpn, and DVDFab Virtual Drive, whenever you want, try to uninstall them one by one.
I.e., uninstall Cisco AnyConnect and verify if the issue disappears.
If it does not, uninstall speedvpn and verify if the issue disappears.
If it does not, uninstall DVDFab Virtual Drive and verify if the issue disappears.
