Maintain Frequent Updates
Keep antivirus and antimalware software up to date and conduct scans on a regular basis. On one hand, such advice may seem obvious. On the other hand, you might be amazed by how many basic precautions are frequently overlooked. While much of the malware used in phishing attacks are not detected by most antivirus software, at least some of them are detected, and AV vendors are becoming more aware of that need. Also, AV software can help identify additional issues with your systems.
