Com Surrogate is not a virus, instead it is a process linked to Dllhost.exe. Com Surrogate might be overusing CPU resources even though is not a virus or a malware, it might not even be directly messing with dllhost.exe. It’s a lot simpler than that, all it takes is a pictures folder where a hidden file such as “desktop.ini” or “thumbs” has been corrupted. The affected folder is usually saved directly on the desktop. To check this go to : Computer / Properties / Advanced system settings / Performance (Settings) and make sure the option “Show thumbnails instead of icons” is deselected. If using Windows Process Explorer (https://technet.microsoft.com/en-us/sysinternals/processexplorer.aspx) you can right click the dllhost file causing the problem and kill it, the process won’t start again. To permanently fix the issue you must find the corrupted file.
The resources overusing problem linked to Com Surrogate could be caused by a hidden file that was affected by a virus, most likely an adware. The best way to fix this is cleaning your computer with the help of the free tools recommended in our guide below.
