What is osascript in my Automation tab in securities?

Some some more info on malware:

First, there is no reason to ever install or run any 3rd party "cleaning", "optimizing", "speed-up", anti-virus, VPN or security apps on your Mac.  This documents describe what you need to know and do in order to protect your Mac: Effective defenses against malware and other threats - Apple Community and Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support.  

There are no known viruses, i.e. self propagating, for Macs.  There are, however, adware and malware which require the user to install although unwittingly most of the time thru sneaky links, etc.   

Anti Virus developers try to group all types as viruses into their ad campaigns of fear.  They do a poor job of the detecting and isolating the adware and malware.  Since there are no viruses these apps use up a lot of system resources searching for what is non-existent and adversely affect system and app performance.

There is one app, Malwarebytes, which was developed by a long time contributor to these forums and a highly respected member of the computer security community, that is designed solely to seek out adware and known malware and remove it.  The free version is more than adequate for most users.  

Unless you're using a true VPN tunnel, such as between you and your employer's, school's or bank's servers, they provide false security from a privacy standpoint.  Read these two articles: Public VPN's are anything but private and Former Malware Distributor Kape Technologies Now Owns a Number of Public VPNs and a Collection of VPN “Review” Websites.  

Just some additional food for thought.

You cannot be assured that what TotalAV anti-virus is finding is real malware, or offering up valid sacrificial false positive files from the operating system or application internals that it misassociates and labels as malware. If you quarantine the wrong file, it could bring down the operating system or cause unexplainable misbehavior in valid applications or data. Windows targeting malware and real viruses do not run on Macs.

If you want to look for malware without whacking the operating system or applications, I would entirely remove TotalAV per the vendor's removal instructions, and use Malwarebytes for that purpose.

Osascript is installed by all versions of macOS and is for running AppleScript or JavaScript for Automation scripts at the command line, or incorporating AppleScript into a shell script function.

No viruses can infect macOS Monterey, Ventura, or Sonoma because the operating system is on a code-signed, read-only volume. Even turning SIP off will not gain write access to this volume. Additional to that fact, is that Apple has taken proactive steps with the security design of the operating system and hardware as discussed in:

Apple Platform Security - Apple Support

This does not preclude the possibility of introducing other forms of malware into your Mac as baggage on software downloaded from anywhere other than the original developer's site. The free Malwarebytes for Mac is usually recommended here for malware detection and removal. We do not recommend installing any anti-virus software as it has proven over the years to be a source of complaints regarding application and operating system interference and performance loss. You Mac is not the screen door on a submarine that Windows has, and currently represents.

You are welcome.
