Came up with an installation for a game. So far, harmless.

precomp.exe had taken hold of random files and refused access(moving, deleting) to the files. Once I ended the prossess in my task manager I was then able to move rename and delete files again.
it takes processor memory it slows the computer down
Pops up when unpacking GTA V

Precomp.exe is an known bitcoin miner. A way for people who put illegal content on the internet to make money of it.
It is used in a setup process of a game I'm installing, and so it is important but once the setup is finished I'm going to remove that program. I tried ending process, before finding out it is part of the setup, and the setup simply stopped, still working (didnt crash or go "Not Responding")thus I know it is helping the setup and also in the subfolder in Temp it is located next to files which names are setup and similars. the setup and the precomp.exe both take in average 22%CPU usage for me, although the only the setup takes RAM space. the setup takes almost half a GB RAM yet the precomp only takes 2MB of RAM.
It's an application used in installation of games like max Payne 3,cod,just cause and many more . And it will automatically disappear from task manager when game successfully installed .

this causes my computer run sluggish. task manager and resource monitor shows that it takes 50% of my cpu usage. probably it came with a game because windows7 is new installed.
came with cracked game (GTA V), used to decompress highly compressed data by the look of things. safe enough
its necessary for windows installations
Part of the installation of GTAV
Came with a pirated game. SuperAntiSpyware detected it as a Trojan.
It came up when installing gta v and got 27% of my cpu and 24mb ram

Installed alongside a pirated version of GTA IV. It's running from AppData\Local\Temp
This process only shows up while i'm installing games. Although it does use up to 50% CPU and 8 Mb Ram
I have experienced it with many games installation process . as soon as installation starts it starts and takes a lot of cpu and memory . But overall harmless .
Like someone already said, its a game decompresser, it takes resources but only until the game setup

Best practices for resolving precomp issues

A clean and tidy computer is the key requirement for avoiding problems with precomp. 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.

To help you analyze the precomp.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
