All malicious programs are covered under the umbrella term malware - adware, ransomware, rootkits, spyware, trojans, worms,  and viruses - all are considered malware. It is important that you regularly check your computer for malware, as a malware infection puts your personal data at risk. Keep all system software up to date to reduce the risk of infection.

Symptoms of Malware

• Your computer or web browser has dramatically slowed down over a period of a few days/a week
• Frequent freezing or crashing
• Modified or deleted files
• New programs or desktop icons that you do not recall installing/creating
• Programs running without your consent
• Programs closing without your consent
• Changes in your security settings
• Unusual emails/social media messages being sent without your permission to a large audience
• Pop-up advertisements:  Most browsers suppress these by default so if you are getting them, something has changed those settings (or you have otherwise explicitly allowed pop-ups)
• Your default search engine has been changed without you altering it
• New toolbars in the web browser
• Browser links redirect to the wrong web page
