k2server.exe is a key component of Verity/Autonomy K2a a text-indexing product. Would only be dangerous if the file is infected by some other program

Maybe Virus, UNLESS you are running a local Coldfusion MX server. In Windows the ColdFusion MX 7 Verity Search Server service manages and controls configuration and services of a Verity K2 domain. This service starts three processes: k2server.exe, k2index.exe, and k2admin.exe
This is Verity K2 - an indexing and search product. It is also bundled with ColdFusion versions from 4.5 to 8.

Best practices for resolving k2server issues

A clean and tidy computer is the key requirement for avoiding problems with k2server. 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.
