It's worthy that you're keeping a close eye on your system and that your scan didn't flag the "Infatica Service App.exe" as malicious. However, its unexpected appearance is indeed worth investigating further.
"Infatica Service App.exe" is typically associated with the Infatica P2P proxy network. This software turns your device into a node within their peer-to-peer network, which can be used for various tasks by their clients, including web scraping, ad verification, and other purposes that require real IP addresses.
If you don't recall installing this or consenting to it, it’s possible it came bundled with another application. Sometimes freeware or shareware includes additional software in its installer unless explicitly deselected during the installation process.
I would reccommend revisiting what applications you've recently installed and checking their installation processes for any mention of bundled software. Additionally, keep monitoring your system for any unusual activity and consider reinforcing your firewall settings to prevent unauthorized access to your network.
Your vigilance is definitely your best defense in maintaining the security and integrity of your system!
