“Some basic guidelines are: Don’t click on links within emails from unknown sources (no matter how curious you might be). Don’t open attachments from unknown sources (malware can be embedded into many different files, such as Portable Document Format (PDF) files, Word documents, Zip files, and more). Be wary of free downloads from the Internet (Trojans entice you with something free but include malware). Limit information you post on social media sites (criminals use this to answer password reset questions). Back up your data regularly (unless you’re willing to see it disappear forever). Keep your computer up to date with current patches (but beware of zero-day exploits). Keep antivirus software up to date (but don’t depend on it to catch everything).”
