Antivirus found malware(Farbar log)


Recommended Posts

Hello, this is my last post so I have done Malwarebyte scan and Farbar scan so I have attached logs from that one. Blow is my first post:

Recently I got some problems with my laptop (HDD scratching, CPU and HDD usage 90%-100%, Win10 can't go to sleep!) so I downloaded antivirus and run scan. During scan it found 5 malware and one of them is Trojan.Multi.GenAutorunReg.c.. Some are deleted and some disinfected but problems are still here. When I run task manager it shows System interrupts process is using 90% of CPU and other problem with Windows sleep is still there.

I wonder if antivirus deleted all infected files and is there something I can do about that or I should reinstall Windows.

Thank you in advance.

Hi, 

My name is Maurice. I will be helping and guiding you, going forward on this case.

Let me know what first name you prefer to go by.

 

Please follow my directions as we go along.  Please do not do any changes on your own without first checking with me.

If you will be away for more than 3 consecutive days,  do try to let me know ahead of time, as much as possible.

 

Please only just attach   all report files, etc  that I ask for as we go along.

I downloaded antivirus and run scan

Just exactly which program is that ?   Did you mean Kaspersky ?  or what ?

This system does have Kaspersky Total Security.   Have you done a scan with Kaspersky?

Lets hold off on any Windows reinstall for the time being.

 

Let's please do what follows.   Do all of these.  Have lots of patience in all things.

You can check this system using another free tool at Microsoft.  For another opinion.

The Microsoft Safety Scanner is a free stand-alone virus scanner that  can be used to scan for & remove malware or potentially unwanted software from a system.

The download links & the how-to-run-the tool are at this link at Microsoft

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

 

take a minute to locate & then send the log that it made, named msert.log

It should be at C:\Windows\debug\msert.log

I would suggest a free scan with the ESET Online Scanner
Go to https://www.eset.com/us/home/online-scanner/

Look on the right side of the page.  Click Scan Now
It will start a download of "esetonlinescanner_enu.exe"
Save the file to your system, such as the Downloads folder, or else to the Desktop.

Go to the saved file, and double click it to get it started.
When presented with the initial ESET options, click on "Computer Scan".

Next, when prompted by Windows, allow it to start by clicking Yes

When prompted for scan type, Click on Full scan
Look at & tick  ( select )   the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"   and click on Start scan button.

Have patience.  The entire process may take an hour or more. There is an initial update download.
There is a progress window display.
You should ignore all prompts to get the ESET antivirus software program.   ( e.g.  their standard program).   You do not need to buy or get or install anything else.

When the scan is completed, if something was found, it will show a screen with the number of detected items.  If so, click the button marked “View detected results”.

Click The blue “Save scan log” to save the log.

If something was removed and you know it is a false finding, you may click on the blue ”Restore cleaned files”  ( in blue, at bottom).

Press Continue when all done.  You should click to off the offer for “periodic scanning”.

Hi Maurice,

My name is Nikola.

I have done scan with Kaspersky total scan and that's where I saw that Trojan.Multi.GenAutorunReg.c. Also, there was uds dangerousobject.multi.generic, HackTool.MSIL.KMSauto.dc and HackTool.Win32/HackKms.f

I have finished scan with that Microsoft tool and I have attached log you were asking, but ESET online scanner couldn't start. After double click nothing happens and it shows in Task manager for 3-4 seconds and then just disappears. Let me know if you have some solution.

I thought you should maybe know these details, even they are maybe not connected to same problem but I found somewhere it could be virus infection:

-Few times I tried to put laptop on sleep but it ended with black screen and infinite HDD sound (HDD still working), and when I tried to wake it up nothing happened so I had to hard reset it.

 But later, few times I hadn't problems with sleep. 

-Seccond strange thing is CPU usage by System interrupts and it shows only 1-2 second after I open Task manager, after that uses 2-3% CPU. I attached screenshot of that.

 

Thank you for your time and I hope we will resolve this soon.

Hi Nikola.

Thanks for the report.   The least of any issue is the initial display of Task Manager.  Lets stay out of Task Manager.  The display readout in the initial first 30 seconds or so is not to be taken as the real deal.  It takes task manager a while for it to settle down to the real deal.  Lets not use it.  It is best to just count on known security checking tools.

I will be your guide & coach.

You indicated  the ESET Online scan tool  was unable to run or perhaps blocked from running.

Let us go forward by doing these steps, please.  If you have questions as we go along, stop and ask me first.

Please download Rkill from one of the following links and save to your Desktop:

One, Two,Three or Four

 

  • Double click on Rkill.
  • A command window will open then disappear upon completion, this is normal.
  • Please post the log

 

Note: If your security software warns about Rkill, please ignore and allow the download to continue.

But whatever happens, be sure you go ahead and do the following steps  for sure.   Thanks.

Let’s  please try to get and run a special  report  tool from Microsoft. 

It does not make changes. It will be just a report.

 

  • Please download Sysinternals Autoruns from here and save it to your desktop.
  • Note: you also need to do the following:
  • Right-click on Autoruns.exe and select Properties
  • Click on the Compatibility tab
  • Under Privilege Level check the box next to Run this program as an administrator
  • Click on Apply then click OK


Double-click Autoruns.exe to run it.
Once it starts, please press the Esc key on your keyboard.
Now that scanning is stopped, click on the Options button at the top of the program and select Filter Options...

In the Autoruns Filter Options dialogue, verify that the following are unchecked, if they are checked, uncheck them:

  • Include empty locations
  • Hide Microsoft entries
  • Hide Windows entries


Verify that the following is checked, if it is unchecked, check it:

  • Verify code signatures


Once that's done press the F5 key on your keyboard, this will start the scan again, this time let it finish.
When it's finished and says Ready. on the lower left of the program window, please click on the File button at the top of the program and select Save and save the Autoruns.arn file to your desktop and close Autoruns.


Right click on the Autoruns.arn file on your desktop and hover your mouse over Send To and select Compressed (zipped) Folder
Attach the Autoruns.zip folder you just created to your next reply

 

Thank you.

Thank you for the reports.

Can you check the Kaspersky Total Security & check to see if it has all the latest updated ?

Start Kaspersky.   Click Settings icon.

Click on "Additional"  from the list.

Click "Update".

 

Next,   I would like to ask you to run a scan with Kaspersky Total Security

When all done, kindly let me know the result.

Hey, 

I have done scan, everything is OK.

I guess that I don't need to go further. I just wanted to be sure there is no remains of few threats from the start of topic.

Thank you for your help, it was really professional and accurate. I really appreciate it.

You are very welcome.  I will guide you to cleaning up the tools we used.

 

I would like you to run a tool named SecurityCheck to inquire on the current-security-update  status  of some applications.

  • Download SecurityCheck by glax24 from here and save the tool on the desktop.
  • Right-click  with your mouse on the Securitycheck.exe  and select "Run as administrator"   and reply YES to allow to run & go forward
  • Wait for the scan to finish. It will open in a text file named SecurityType.txt. Close the file.  Attach it with your next reply.
  • You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt

I suggest you uninstall  Java SE Development Kit 8 Update 231 (64-bit) v.8.0.2310.11 .   That is out of date.  

The pc does have the Java 8 Update 241 (64-bit) v.8.0.2410.7

.

Once that is done, the pc is good to go.  This is for cleanup of tools we used:

Delete MSERT.exe

Delete esetonlinescanner_enu.exe

Delete RKILL

also Securitycheck.exe

also Autoruns.exe

To remove the FRST64 tool & its work files, do this.  Go to your Downloads folder.  Do a RIGHT-click on FRST64.exe & select RENAME & then change it to UNINSTALL.

Then run that ( double click on it)  to begin the cleanup process.

 

Anything else that I had you download, you may delete.

.

These are some best practices to keep the pc & your stuff on the pc safe.

The first best practice of computer safety is to have backups of the system.  Make regular periodic backups to offline removable media.

Backup is your best friend.

 

It is not enough to just have a security program installed. Each pc user needs to practice daily safe computer and internet use.

 

Best  practices & malware prevention:
Follow best practices when browsing the Internet, especially on opening links coming from untrusted sources.
First rule of internet safety: slow down & think before you "click".

Never click links without first hovering your mouse over the link and seeing if it is going to an odd address ( one that does not fit or is odd looking or has typos).


Free games & free programs are like "candy". We do not accept them from "strangers".


Never open attachments that come with unexpected ( out of the blue ) email no matter how enticing.
Never open attachments from the email itself. Do not double click in the email. Always Save first and then scan with antivirus program.
 

 

Pay close attention when installing 3rd-party programs. It is important that you pay attention to the license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed.
Take great care in every stage of the process and every offer screen, and make sure you know what it is you're agreeing to before you click "Next".

Use a Standard user account rather than an administrator-rights account when "surfing" the web.
See more info on Corrine's SecurityGarden Blog http://securitygarden.blogspot.com/p/blog-page_7.html
Dont remove your current login. Just use the new Standard-user-level one for everyday use while on the internet.

 
Do a Windows Update.

Make certain that Automatic Updates is enabled.
https://support.microsoft.com/en-us/help/12373/windows-update-faq




Keep your system and programs up to date. Several programs release security updates on a regular basis to patch vulnerabilities. Keeping your software patched up prevents attackers from being able to exploit them to drop malware.

For other added tips, read "10 easy ways to prevent malware infection"

I wish you all the very best.  Stay safe.  Keep safe.

Sincerely,

Maurice
