|pagefile.sys is locked by the System process for exclusive access so it cannot be accessed by any other process, including anti-virus products. This is normal and the way it should be. Since no other process can access the pagefile it cannot be directly infected by any form of malware.|
You can configure the antivirus product to not attempt the scan of this file. There is no way it is going to be able to do it anyway. The same applies to hiberfil.sys if hibernation is enabled.
Be aware that having 2 or more active ant-virus products is not recommended, can lead to reduced protection, and will impair performance.
