Anti-virus software protects your computer from viruses, spyware, and other malicious software. It works by looking for patterns of known worms and viruses in files you download and in programs that are running on your computer. Since bad actors are always creating new worms and viruses, your virus protection software needs to be regularly updated to recognize the latest threats.

Anti-Virus Software Installation

New viruses, malware, and spyware threats are identified everyday, and your protective software is only as strong as your most recent update.

Preventing Viruses

• Avoid downloading software from the internet. Whether using a Mac or PC, download software only from the corresponding App Store.
• Do not click links in emails. Hackers are constantly coming up with creative ways to install viruses on your computer. Be mindful of what you click in emails. Check out Identifying Malicious Emails to see some common characteristics of phishing emails.
