After this file appeared on my computer it started blocking important ports I needed for software development, seemingly maliciously. Everything worked again once I removed it from my system.

PC security management (corporate) allows for ur system to be monitored by security
"enstart.exe" is a default app name for Guidance Software's EnCase forensic enterprise client application. Normally, the name should be obfuscated, but some places may not have felt this necessary. If you're part of a large org and you see this process running, ask your IT security POC for guidance before deleting/modifying. Then again, file/app names are largely arbitrary - it is possible that it's malcode masquerading as a legitimate service.

An article in 2600 magazine claims that it's company-issued spyware, to track your actions.
This is installed on my company computer, so it is possible that it is corporate nanny-ware.

Best practices for resolving enstart issues

A clean and tidy computer is the key requirement for avoiding problems with enstart. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
