How can you help keep your computer virus-free?

To maintain a virus-free computer, it is crucial to be discerning about which emails and their contents you open. By examining the subject line and the sender's information before opening an email, you can identify potentially suspicious messages that may contain harmful attachments or links. Many viruses and malware are often spread through deceptive emails, commonly referred to as phishing scams. This vigilant approach allows users to make informed decisions about whether to open an email or delete it, minimizing the risk of downloading malicious software onto their systems.

Other methods, such as limiting email access to the company intranet or restricting file openings based solely on specific suffixes, may not be as effective. For example, only opening files with certain extensions could still expose you to risks since threats can use a variety of file types. Thus, the best preventive measure is to carefully assess each email you receive before deciding to interact with it.
