Windows 10: Help pls .. Unknown.exe high CPU usage

Ok so I am new here and really need some help

So from yesterday I have been getting this unknown process in task manager, its an application (.exe).
It has very high cpu usage making my computer really slow.











I tried ending process from task manager but it will just pop up again.

Well when I disconnect internet and than end process it works but again when its connected to internet 'unknown' appears.

I tried cc cleaner, microsoft safety scanner, full scan but nothing.

If someone can help me much appreciated. and sorry for my bad english typing.

:)

 

Is Unknown.exe safe or not?

There's a file called Unknown.exe in the task manager, which is taking up all the CPU resources, and is making the laptop extremely slow. How do I get rid of it?

Windows 10 unexpected shutdowns

Right-click Taskbar and click Task Manager. On the processes tab, you will see what processes are taking the high CPU percentages. Scroll down to the bottom. Also note the memory usages. You may have a memory leak issue.

If you notice any anomalies about CPU usages and memory levels, then pls let us know.

 

It looks like malware mining for bitcoins - Malware scan of unknown.exe

You could try deleting C:\ProgramData\Unknown\Unknown.exe (and C:\ProgramData\Unknown.exe if it is there) but it will most likely come back.

Running a Malwarebytes scan should get rid of it if it does as there are lots of reports of this file in their logs on the internet. You can download the free version from here Malwarebytes | Malwarebytes Anti-Malware Premium

 

Miners can be bundled with legitimate software, it is becoming more adware than malware these days.
So most AVs will not detect it, or they will detect it as PUP (potentially unwanted program) at best.
Check installed programs, if there is something you do not know, uninstall what you do not use.

Indeed, since it is coming back, take ownership of the folder or just exe and then remove all users.
No one will be able to run it, it will fail and maybe you will get a popup, what tries to start it.

Add Take Ownership to Context Menu in Windows 10

 

Once you have got rid of it, start using a freeware tool to prompt you if anything is added to the list of startups. That way you can reject it.

However some things are persistent, and will try again an again.

For example:
Winpatrol
Mike Lin's ancient Startup Monitor

Also start using disk imaging and update your image periodically. This can help you restore your PC to a working state in 20 mins, say, without technical help.

 

I also have had the same unknown.exe problem Via taskmanager I saw it using up all of the spare processeur power i.e. always at 100%
but now ,after using malwarebytes; as above,-THANKS Ix07 its gone but malwarebytes is using between 15 & 20% and windows commands translator 10%.
Is this normal?
