That is a very bad sign if you have keylogging programs installed on your PC. First of all, I would recommend getting a free Firewall software to block these programs (ZoneAlarm is pretty good).
If you try running our virus scanner (https://www.pcreview.co.uk/antivirus.php) you may be able to clear some of the problems up. Other than that, I suggest seeing if any suspicious programs appear in the task list when you press CTRL-ALT-DEL?
