First run a full system scan. With ClamAv on. I would also scan with Defender.
What AVs do you have or is Immunet you main? Is Defender flagging anything?
Those files do look suspicious, but could be false positives. Since these are copy and paste I can't dive in to the files much. Try uploading the files to Virustotal, https://www.virustotal.com. It's a drag and drop site and it's easy to get a good idea if its bad or not. After you do that we should know more if its a true threat or a false positive.
What's your OS i.e Win7 or 10. Pro of home version
Are you using Internet explorer? The reason I ask is the first file path with INetcache/IE looks like a toolbar has installed itself to IE.
Why it seems to install when your start your system is most likely is set to startup automatically when you turn on your computer. You can disable this in a few ways, but the easiest is go to task manager ->startup tab -> find the program and select it and at the bottom right hit disable. With that said if it's malware it may hide itself for being seen.
Sorry if this seems like a quick response It's a very busy day for me, but I will help where I can:)
Let me know what virusTotal says so I can help with what needs to be done next.
