main.exe is a file coming from a tor hidden service. By my observations and headbanging for 2 days i found a site for bit coins( that is arrogantly spreading software, which is using other PCs resources. On my PC it was using about 700mb of memory. Went into the registry found the service BITS (background intelligent transfer service) it is a windows service but i didn't like it anyway. And the creation of main.exe stopped and with it the background usage of my resources.

Best practices for resolving main issues

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