It is sometimes necessary to temporarily disable virus protection when installing major updates such as Windows Service Packs or updating graphics card drivers. Active antivirus protection may partially or completely prevent the installation of a major update.
Support issues also exist around antivirus application interoperability with common solutions like SSL VPN remote access and network access control products. Often, these technology solutions have policy assessment applications which require that 1. an antivirus is installed 2. that the product is running and 3. that the application's signatures are up to date.
If the antivirus application is not recognized by the policy assessment, whether because the antivirus application has been updated or because it is not part of the policy assessment library, the user will be unable to connect. Interoperability testing and certification for antivirus applications is offered by the OESIS OK Program.
