It is a self multi copy virus. It re-copies itself everytime if you try to delete it. One way to remove it: create a small partition, move every x.exe from every partition on the new small one, and format the partition

x.exe located in C:\Program Files\Xactware\Xactimate25\CORE is an Xactimate core file.
x.exe is used by Topologo Linux designed to run either within Windows or dual boot. If you are not using some type of Linux/Unix OS or port on your PC, then it may be some other form of bug.

Best practices for resolving x issues

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