Hello. I have a computer that has been acting strange for quite some time. The problem behavior is random, but usually seems to involve explorer.exe. One of the main symptoms is an error moving files from any exterior component (i.e. external USB hard drive, USB flash drive, iPhone). The moving file process will spontaneously abort, usually stating that the device has been removed, or some sort of random access error. When I reboot the computer, a warning screen will pop up stating that explorer.exe is preventing the computer from restarting. This does not always happen, sometimes allowing the process to complete fully without errors. Also, explorer.exe seems to always use a lot of CPU. In addition, there are several instances of svchost.exe running, using up memory and CPU.

 

I have tried many troubleshooting steps, including updating drivers, multiple virus scans (Windows Defender and Malwarebytes), moving the USB device to other USB inputs, multiple check on hardware, etc. The USB devices work fine on other computers.

 

I have tried reformatting the hard drive and re-installing Windows 10 a few times over the past few months, but the problem seems to reappear within a few weeks. 

 

My major concern is that I have some sort of virus. Is there a way to tell?

 

The computer is running Windows 10 Home 64-bit, Version 1709, OS Build 16299.192

 

Thank you!

You're Welcome!!
Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.
Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 3 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
