Some other suggestions

I strongly support setting and utilizing complex passwords on your devices which are rotated periodically, and always encrypt local storage devices, especially on portable systems, to reduce the risk of access to browser data.

Use physical security such as cable locks for laptops, and always lock the screen of your systems when not in use (I do this on my home Windows PC as well). Don’t share machines/passwords with other people.

Take advantage of two-factor authentication where possible and set up recovery accounts where possible for your website accounts, and specify your mobile number and security questions for password resets. Be on the lookout for suspicious activity like emails about new accounts or password resets you didn’t request.

Some sites like Facebook can tell who is currently logged into your account (go to Settings then Security and Login), so check these details periodically – especially if anything out of the ordinary is going on.

Exabeam also recommends utilizing anti-malware software which is routinely updated along with several browser-related options (Google your browser and operating system version for the specific details on how to enact these as settings may change).

Users should also consider changing browser settings to further protect their privacy, or at least analyzing them to be aware of what options are currently enabled/disabled. There are guides online for Chrome, Firefox, Internet Explorer, Safari and Opera.
