Even if you don't have a keylogger installed, you should still occasionally do a virus sweep so this is what I'd recommend.
First, Run rkill.com. Sometimes it takes a few minutes to finish. Do not reboot when done.
Kills running malicious processes
Removes policies in the registry that prevent normal OS operation
Repairs file extension hijacks
Next, Download an updated copy Malwarebytes' Anti-Malware. Turn on the “Scan for Rootkits” option. Then, run a “Threat Scan”
Successfully removes the vast majority of infections
Has an industry-leading built-in rootkit/bootkit scanning engine
Has built-in repair tools to fix damage done by malware
After that, run ADWCleaner using the “Scan” option. Then press “Cleaning” when finished and allow it to reboot your system.
Removes majority of adware, PuPs, Toolbars, and Browser hijacks
Fixes proxy settings changed by malware
Removes certain non-default browser settings
Finally, Run Malwarebytes' Junkware Removal Tool and allow it to finish. Reboot your computer upon completion.
Removes adware, PuPs, Toolbars, and Browser hijacks other tools miss
Good at removing unneeded AppData directories left behind by infections
Follow-up Steps (highly recommended):
Using a computer that has not been infected, change passwords to all your online accounts.
Consider enabling two-factor authentication.
