Need Help Removing WR64.sys, Appear Every Restart

[allbeeeee]

I am not experienced, but I have done some research on this and tried some fixes, to no avail.

I think has been a month or two where I noticed that my laptop would have loud fan noise even though it is idle. When I opened task manager, it will have high CPU load at around 40% - 70%, which will then immediately drop down to around 7% after opening, and the fan noise will go quiet. When I closed task manager, the fan noise will get louder and CPU load increased again. I used HWinfo to track the CPU load, and indeed the CPU load will maintain at around 40% after I closed task manager, and less than 10% when task manager is open. I suspect I have a cryptomining malware.

As the title says, the WR64.sys always re-appear in the path System32\..\AppData\Roaming\Google\Libs\WR64.sys

Additionally, I have tried scanning with:

• FRSTEnglish.exe: I will attach the logs FRST.exe and Addition.txt
• microsoft safety scanner: "Threat Detected: TrojanDownloader:JS/Swabfex.P and Removed!" but will always get detected again after restart. I will attach the log.
• adwcleaner.exe: no detection
• esetonlinescanner.exe: unable to download update module, will always crash or progress resetting to 1% and have tried multiple times. When launching the .exe in %appdata%, then I can get it to do full scan, which resulted in some detections. I will also attach the log.

I have also turned off sync on my google account and cleared the sync data before doing these scans. After restart (without turning on the sync), the WR64.sys is back.

• Temporarily disable your antivirus real-time protection or other security software first only if it blocks or interferes with the scans or downloads. Make sure to turn it back on once the scans are completed.
• Temporarily disable Microsoft SmartScreen to download software below only if needed. Make sure to turn it back on once the downloads are completed.

I have restarted my laptop, so the WR64.sys should re-appear again. Then I did the scans mentioned above:

• Adwcleaner: no items were detected. Log is attached.
• Malwarebytes: Found the WR64.sys and quarantined. There is only one. Log is attached.
• FRST: Ran the scan as admin. Log attached.

So far, there are only 4 logs produced. I don't know about the fifth log mentioned and couldn't find it.

Hello @allbeeeee:

In the case of the computer in question, the Malwarebytes AdwCleaner's Clean log was written to C:\AdwCleaner\Logs\AdwCleaner[C04].txt.

Thank you.

[allbeeeee]

Thanks for the swift response, I have attached the AdwCleaner log in the above reply post. However, it is S04 instead of C04 though.

Welcome 
 
I'll be helping you with your computer.
 
Please read this post completely before beginning. If there's anything that you do not understand, please don't hesitate to ask before proceeding.
 
Please take note of the guidelines for this fix:

• Please note that I am a volunteer. I do have a family, a career, and other endeavors that may prevent immediate responses that meet your schedule. Do note that the differences in time zones could present a problem as well. Your patience and understanding will be greatly appreciated.
• First of all, the procedures we are about to perform are specific to your problem and should only be used on this specific computer.
• Do not make any changes to your computer that include installing/uninstalling programs, deleting files, modifying the registry, nor running scanners or tools of any kind unless specifically requested by me.
• Please read ALL instructions carefully and perform the steps fully and in the order they are written.
• If things appear to be better, let me know. Just because the symptoms no longer exist as before, does not mean that you are clean.
• Continue to read and follow my instructions until I tell you that your machine is clean.
• If you have any questions at all, please do not hesitate to ask before performing the task that I ask of you, and please wait for my reply before you proceed.
• Scanning with programs and reading the logs do take a fair amount of time. Again, your patience will be necessary. 

Let's begin... 

The following Fix will empty these folders:

• Windows Temp
• Users Temp folders
• Edge, IE, FF, Chrome, and Opera caches, HTML5 storages, Cookies and History

• Explorer thumbnail and icon cache
• BITS transfer queue (qmgr*.dat files)
• Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns, please ask before running this fix.

The system will be rebooted after the fix has run.

Please attach this file in your next reply.

Dr.Web CureIt!

Please download the Dr.Web CureIt! anti-virus utility

You will need to send them an email to obtain a link to download the scanner, please do so

• The downloaded file will normally have a unique name such as:  q7a9tr4p.exe
• Close all open applications and locate the downloaded file and double-click to run it

[allbeeeee]

I have applied the fix and ran the Dr. Web scan as instructed. Dr. Web did not detect any threats. I have attached the logs.

Additionally, it seems like my fan noise is no longer loud when I close my task manager. To let you know 😀

The script did not run well. Lets try this again:

How is the computer doing?
 

[allbeeeee]

Hi, my laptop seems to be doing better now, no more loud fan noise when idling and malwarebytes scan does not detect WR64.sys anymore after restarting. I assume this issue is fixed? Thank you 😀
