Manage Antivirus and Antimalware
Antivirus / Antimalware software protects your from malicious intrusion... There are many softwrae vendors, providing both signature and/or behaviour based products.
Choose an Antivirus / Antimalware that best suits your entrprise. This choice can be (partly) driven by cost, easy of use, facility of deployment or ease of updating. Choose an antivirus that is adapted to your specific needs... do you only seek to protect workstations, or do you also have servers, email systems, firewalls or web-browser proxies that you want to protect?
Regardless of the Antivirus solution you choose, make sure that your users are aware of the importance of updating, and that they are able to recognise and handle virus and malware alerts.
