I know that this virus is really dissapointing
Junto a DOMINO.exe son procesos del software para Webcams de VIMICRO
essspk.exe hat die selbe dateigröße wie domino.exe und vmsnap3.exe, essspk scheint ja zum modem zu gehören, die anderen beiden dateien zu einer webcam. ich frage mich, warum es mehrere dateien gibt die identisch aussehen (heine herstellerangaben etc), gleich groß sind, mit windows gestartet werden aber scheinbar einen ganz unterschiedlichen zweck erfüllen trotz identischer dateigröße, müsste nicht wenn die dateien etwas unterschiedliches tun auch der code unterschiedlich groß sein?
Comes with webcam, takes up resources of pc - therefore lags it.
came with webcam software. ZSMCSNAP, 49.152 bytes, BIGDOG

Best practices for resolving vmsnap3 issues

A clean and tidy computer is the key requirement for avoiding problems with vmsnap3. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the vmsnap3.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
