Add Pagefile.sys to Antivirus exceptions
I would like to know, as the title says, if it's possible to add C:\Pagefile.sys to the Exceptions list in the settings. The said file can't be chosen as a file to be excepted via the Browse for files Dialog box. However, copy-pasting the file path into the relevant field does activate the three fields below: Antivirus, Online Threat Prevention & Advance Threat Defense. The downside is only Online Threat Prevention is accessible with the other two options grayed out. This is in spite of running the BD client with elevated privileges.
Are there any tricks to unlock the grayed out fields. I have a specific need for exempting the file from active scanning to test something unrelated, although Bitdefender maybe playing it's part in causing the specific issue.
