after upgrading to Ventura, everytime I launch a window full of .bin files opens up.

First give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

Also check to see if there are any unusual items in the User Login Items setting.

Have you installed and run any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac?

This seems to be a bug in the installation procedure for Ventura. Please determine if the following Discussion describes what you are encountering:

If it is a bug, it's innocuous and easily fixed. Do not install some non-Apple "anti-virus" product.

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.  

Also, unless you're using a true VPN tunnel, such as between you and your employer, school or bank's servers, they are are no guarantee from a privacy standpoint.  Read these two articles: Public VPN's are anything but private and Former Malware Distributor Kape Technologies Now Owns ExpressVPN, CyberGhost, Private Internet Access, Zenmate, and a Collection of VPN “Review” Websites. 

Some users use VPN to get to websites in other countries that wouldn't be available otherwise. In those cases just don't rely on them for keeping your privacy.

That being said uninstall ClamX according to the developer's instructions. And the VPN if not mandated.

You really don't need either one, and neither one would have had any bearing on this particular problem.

There are plenty of Internet-related scams that seek to exploit people, and Mac users are particularly attractive targets because they're wealthy. Incredibly wealthy. Wealthy beyond measure... on a global standard. There are lowbrow scams, highbrow scams, and everything in between. From the notorious "Nigerian prince" email scams at one extreme to arrogant "We will protect you!" scams typical of "anti-virus" peddlers — the latter being an actual promotional claim made by one such product. They all have the same goal: Follow the money. Works every time. Doesn't matter whether the app is "free" or not.

You don't have to play that game. Effective defenses against malware and other threats - Apple Community describes what I've been doing from the beginning. No "anti-virus" products needed. And, if you should ever find yourself having been deceived into installing something malicious, it's easily remedied on your own, without having to appeal to some expert.

And, like everything else on this site, it's free. Unfortunately that simple fact limits exposure, because the Internet runs on advertising revenue. You are using one of the very few sites (Apple Support Communities) that doesn't get any.
