Avast Business Security Antivirus provides active, centrally-managed anti-malware protection to Lehigh-owned faculty and staff PCs and Macs. On PCs, it is used in combination with a centrally-managed enterprise version of Malwarebytes that is automatically installed as part of the Windows Update process. All other anti-malware software should be removed (or deactivated, in the case of built-in Windows software that cannot be uninstalled, such as Windows Defender).
Remove all other anti-malware products that you have installed, including Microsoft Forefront Endpoint Protection, Norton, Symantec, or McAffee products, or (for Macs) ClamAV.
Note that you will most likely receive warnings about antivirus protection being inactive and out-of-date. This is normal, and nothing to be concerned about. The installation sends a message to the central administrator, who will activate the software (this normally happens in a few minutes to--at most--a few hours).
