Hi Alex,
I would like to ask few questions for a better understanding of this issue.
- What is the exact name of this file? Is the file name “PSS” or is it the file type or extension?
- Where do you find this file on your computer?
- What happens when you double-click on this file?
- What is the name of the application that you have had used to record the keystrokes on the computer?
- What are the recent changes that you have made to the computer before your started noticing this file?
Please answer these questions for a better understanding and to assist you in a better way. If you suspect any virus or other malicious software infection on the computer, then I would suggest you to boot the computer in Safe Mode with Networking and perform a complete security scan using Microsoft Safety Scanner and check the scan results.
Boot the computer in Safe Mode with Networking and Perform a Complete Security Scan
In Windows, we can start the computer in different advanced troubleshooting modes to find and fix problems on the PC. One of such troubleshooting mode is Safe Mode with Networking. Here we start Windows with a minimal set of drivers and services, including the network drivers. Please refer to the steps in this article to boot the computer in safe mode with networking:
***Windows Startup Settings (including safe mode)***
After booting the computer in Safe Mode with Networking, let us download the Microsoft Safety Scanner and perform a complete security scan on the computer.
Run Microsoft Safety Scanner and check if there are any infections on the computer.
You can download and run the Microsoft Safety Scanner from this link:
***Download Microsoft Safety Scanner***
Important: When running a scan using an anti-virus program, any data files that are infected may be cleaned by deleting the file entirely, which means there is a potential for data loss.
Please get back to us with the scan results and other relevant information.
