Pc Locks Up. Mysterious User Account Called Fyk.

Hello,

I am having issues with my Dell Inspiron desktop. It sometimes freezes up and will not let the mouse move causing me to have to restart. Previous scans with Malwarebytes would get hung up on xml files located in this directory: \Users\fyk\AppData\Local\Temp. Once again, this fyk user is unknown to me and I didn't set it up. I performed the scans but did run into some issues along the way listed below:

MGTools would not download to the C: drive. I tried the procedures outlined to fix this but the issue was not any of those. Here is the message I got when attempting to download to the c drive:
----------------------------------------
c\:MGtools.exe

You don’t have permission to save in this location. Contact the administrator to obtain permissions. Would you like to save the fyk folder instead?

Yes NO

----------------------------------------------------

I ran Malwarebytes with success but no Scan log was generated since it did not find any issues. I instead have attached a scan log from 9/28. I hope this helps.

Next issue was running RogueKiller. It froze at this point:
Key: [x64] HKEY_CLASSES_ROOT\CLSID : {2048EEE6-7FA2-11D0-9E6A-00A0C9138C29} and I had to reboot the computer. No log was generated from this as a result. Moved on to the other scans and saved logs.

Next issue:

Running MGTools seemed daunting so I decided to wait till the morning. When I turned on the computer I was given a pop up about Avira installing a new Chrome browser extension called:

----------------------------------------------
Avira Browser Safety 1.12.1
ID: ID: flliilndjeohchalpbbcdekjklbdgfkk
----------------------------------------------------

I found this odd since I did not install it myself. I left it disabled.

Final issue was when running MGTools from my desktop (only option i had). At the point where I had to accept the TrendMicro Agreement I got the pop up message that I saved a screen grab of which is attached.

I am not sure if I am having issues still since the computer has not locked up but logs are attached. Still curious about the fyk user issue and the fact some scans freeze at certain points.

Thanks!

 

Thanks for your help. I performed the tasks you listed and ran the Eset scan. Unfortunately it froze up at the very end. I have attached some screen grabs and the Hitman log.

 

I went back and reran Eset - this time with out any other applications running. Once again, it did not complete the scan and quit working giving a pop up that basically said Eos stopped working due to encountering a problem. I have attached a larger screen grab.

Also, do you know why the administrator account is 'disabled', even though this is what I log into when starting Windows; yet the account 'fyk' is what is active? I read the part where you said you didn't understand why the user account was renamed. I am not sure it was renamed. It does not appear in the list of users under User Accounts in Control Panel. the only one listed is me, Mike Administrator. The only way I found it was searching for 'fyk' when Malwarebyte kept freezing up the other night. Only then did I realize this was a user folder called fyk under the c drive. Do you have any suggestions for finding out how this could have happened or how to disable this account?

Thanks!

 

I ran Kaspersky and it didn't find anything. I am going to follow your previous comments to finalize this thread. I will rename that folder and call it good. Thanks again!
