Hi Ive made the changes in the config file but the alerts are still coming through. I've checked the AV folders and they are correct. Please help?

EXCLUSION FILE

This file filters events received by Aurora Agent based on the originating process's image.
Each line should contain a single regular expression. Empty lines or lines that start with # are ignored.
If a process's image matches any regular expression, all events originating from it will be discarded.
Example: Suppress all events from an AV installation folder
^C:\Program Files\My Antivirus
Exclude all processes under Bitdefender Agent and Bitdefender folder
IMAGE: C:\Program Files\Bitdefender Agent.*
IMAGE: C:\Program Files\Bitdefender.*

Optional: Exclude specific Bitdefender processes (these are covered by the general regex above, but can be left here for clarity)
IMAGE: C:\Program Files\Bitdefender\Bitdefender Security App\bdagent.exe
IMAGE: C:\Program Files\Bitdefender\Bitdefender Security\downloader.exe
IMAGE: C:\Program Files\Bitdefender\Bitdefender Security\updatesrv.exe
IMAGE: C:\Program Files\Bitdefender Agent\27.0.1.287\WatchDog.exe

FALSE POSITIVE FILE:

This file filters log messages for Aurora Agent.
Each line should contain a single regular expression. Empty lines or lines that start with # are ignored.
If a log entry (formatted with the default formatter, like in the log file or the command line), matches any regular
expression, that log entry will be suppressed.
Example: Suppress matches on executables from a specific Program folder
IMAGE: C:\Program Files\my legitimate anomaly
Exclude all log entries related to Bitdefender processes (image and command line)
IMAGE: C:\Program Files\Bitdefender.*
IMAGE: C:\Program Files\Bitdefender Agent.*

Optional: Specific Bitdefender process exclusions (covered by the general regex above, but for clarity)
IMAGE: C:\Program Files\Bitdefender\Bitdefender Security App\bdagent.exe
IMAGE: C:\Program Files\Bitdefender\Bitdefender Security\downloader.exe
IMAGE: C:\Program Files\Bitdefender\Bitdefender Security\updatesrv.exe
IMAGE: C:\Program Files\Bitdefender Agent\27.0.1.287\WatchDog.exe

Add CommandLine-based exclusions (to filter Bitdefender-related command line processes)
COMMANDLINE: C:\Program Files\Bitdefender\Bitdefender Security App\bdagent.exe
COMMANDLINE: C:\Program Files\Bitdefender\Bitdefender Security\downloader.exe
COMMANDLINE: C:\Program Files\Bitdefender\Bitdefender Security\updatesrv.exe

Can someone help?

As it is stated in the docs, the escapes needs to be written in regex form, so escape the backslashes
