Hi,

a few times I reinstalled Windows 10 on my laptop. The reason; sudden high activity of the fan although no action by me on the laptop. Veryfying the Task Manager shows 4 times Com Surrogate. A few fresh installs ago ESET found a Rogue virus and deleted it. Unfortunately this multiple Com Surrogate listing comes back after every new install of Windows 10. I ran Malwarebytes Premium which didn't find anything. Then I ran Frst64 that came up with the following files (see attachment) I can't read (understand) being a "non-nerd". Can anybody tell me if I still have a rootkit virus? Thank you very much in advance.

Hello kjd and welcome to Mawarebytes,

I do not see any obvious malware or infection in your logs, COM Surrogate is a basic Windows process, it is only usually noticed if/when it crashes. Have a read of the following link: https://blogs.msdn.microsoft.com/oldnewthing/20090212-00/?p=19173

Run a scan with ESET and post the produced log...

Hi Kevin,

it took a while but finally I could make the scan with ESET. The onlinescanner didn't find anything but didn't make a logfile. Then I installed the scanner through firefox which made the logfile you'll find in the attachment. Thanks in advance for your reply.

Hi Kevin,

as a matter of fact I don't know. I sent you a log file of  ESET lately. Perhaps you could see how the status is.

The reason that I came here is a multiple activity of com surrogate in the task manager together with high speed of the fan. Being a complete "non-nerd" I did some research on the internet and read that the cause could be malware. But the information was a bit to complicated. Therefore I asked you for help. Meanwhile I know that com surrogate is used by other programs. But I can't figure out if it's okay that com surrogate shows up a few times simultaneously in the taskbar.

Hi Kevin,

thanks for your answer where I might have been a bit unclear about what I would like to know. First I wanted to know if there is malware on my computer. The software you told me to use didn't find anything suspicious which means "so far so good". :-) 

However, Com Surrogate still shows up a few times simultaneously in the task manager and I would like to know if that is nothing to worry about or if it is an indication of possible presence of malware? If I see Com Surrogate listed 3, 4 times the cooler makes a lot of noise.

In short: could I still have malware on my laptop and if so, do you know another program that could find and eliminate it?

You can imagine I'd be luckier if, based on the information I gave, you could guarantee that my laptop is virus free.

Thanks for all your effort so far. Really appreciate.

My system has Com Surrogate entries running, sometimes one sometims two or three, really depends what is happening... Check your entries as follows..

Open Taskmanager, then select Processes. Right click on first "Com Surrogate" entry then select "Open File Location" The file location will open and the file will be highlighted.

Right Click on the file and select "Properties" in the Properties window select "Digitals Signatures" make a note of that result. Repeat for each Com Surrogate entry...
