following steps as countermeasures against software keyloggers:
Actively monitor the programs running on the server.
Monitor the network whenever an application attempts to make a network connection.
Use commercially available anti-keyloggers, such as PrivacyKeyboard.

Update one’s antivirus regularly.
Use on-screen keyboards and speech-to-text conversion software which can also be useful against
keyloggers, as there are no typing or mouse movements involved.

against software keyloggers.
