Trojan site blocked/font file

Recommended Posts

I had removed some malware from a machine a few weeks ago as noted in this thread 

Malware from dl.okblcm.co on computer

I have noticed that Malwarebytes has been blocking a trojan site several times a day and this is the report

In the previous thread I noticed that this file was picked up by MSRT but is still present on my machine. How do I go about removing the file to prevent further trojan site attempts.

Hi.  Thanks for the support tool.  The block notice from Malwarebytes is helping to protect this PC.   The file Up.exe cited in the block message is a trojan.

For more information please see the following:
http://go.microsoft.com/fwlink/?linkid=37020&name=Trojan:Win32/Wacatac.B!ml&threatid=2147735505&enterprise=0

 

I have  procedures below to help out.  The first custom procedure will upload a copy of that Up.exe to Virustotal for analysis  & then remove it.

There is a lot listed below in 5 parts.  Take your time.  Do all of them.  Just go down the list as time permits.

First, set Windows to show all folders, all hidden folders

see   https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files

This Thread/topic is for member C0nrad only. who is the topic starter.

This fix is for C0nrad only.

 

Please Close and save any open work files before you start this next step.  It will involve a Windows Restart at the end of it.

I am sending a   custom Fix script which is going to be used by the FRST tool. They will both work together as a pair.

Please RIGHT-click the (attached file named) FIXLIST and select SAVE AS and save it directly ( as is) to the Downloads folder

The tool named FRSTENGLISH.exe  is already on the Downloads folder.

Start the Windows Explorer and then, open the Downloads folder.


Double click FRSTENGLISH

  to run the tool. If the tool warns you the version is outdated, please download and run the updated version.
Click the Fix button just once, and wait.

PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. Lots of patience. Some machines take longer than others.
If you receive a message that a reboot is required, please make sure you allow it to restart normally.
The tool will complete its run after restart.
When finished, the tool will make a log ( Fixlog.txt) in the same location from where it was run.

Please attach the FIXLOG.txt with your reply.    Also advise on the situation after this run.

Make an adjustment in Malwarebytes for Windows.   Start Malwarebytes for Windows.

Click Settings. Click Application tab.
Scroll down to Windows Action Center.


click on the line "Let Malwarebytes apply the best"

[ 3 ]

Run a scan with Malwarebytes.
Start Malwarebytes from the Start menu.

Click Settings. Then click the Protection tab.
Scroll down and lets be sure the line in SCAN OPTIONs for "Scan for rootkits" is ON
Click it to get it ON


Click the SCAN button.
Select a Threat Scan ( which should be the default).

When the scan phase is done, { if anything detected}   be real sure you Review and have all detected lines items check-marked on each line on the left. That too is very critical.

Then click on Quarantine selected.

 

Be sure all items were removed. Let it remove what it has detected.


When that is completed, kindly send the report.
In Malwarebytes.
Click the Reports button ( on the left )
Look for the "Scan Report" that has the most recent Date and time.

When located, click the check box for it and click on View Report.

Run a scan with the Windows' Windows Defender antivirus.   I would recommend a FULL scan with Windows Defender.

Type “Windows Defender” in the  Windows  search box and then press Enter. Click Settings and make sure there is a checkmark on Turn on real-time protection recommend.

[ 5 ]

A further scan that I suggest.

The Microsoft Safety Scanner  is a free Microsoft 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

 

Let me know the result of this.

Hello thanks for your help thus far

 

Below is the fixlog, along with the scan report from step 3.

 

However, I can not complete step 4. Upon opening windows defender there is a pop up that states "This app has been turned off and isn't monitoring your computer." 

 

After going into the action center of control panel and under the security tab, "Malwarebytes is turned on" is listed under the virus protection where I would normally find Windows Defender. Is this correct? I have the end point protection from Malwarebytes

 

Thanks

Thank you for the reports.  This pc has the consumer Malwarebytes for Windows, version 3.8.3.2965

The last scan run found no malware;  no P U P

The Fixlist run indicates that the "up.exe" in the Fonts sub-folder is no longer present.   That would tend to mean that the original block notice should be no more.

 

As to the display in Windows Security Center / Action Center, make this adjustment here.

go into Malwarebytes.
Click Settings. Click Application tab.
Scroll down to Windows Action Center. .

IF it is now on "Let Malwarebytes apply the best" then in that case, click on the line "NEVER register Malwarebytes in the Windows Action Center".

Close the window when this is done.

Let me know if you need other help.

Sincerely.

You are welcome.  I am glad to have helped you.

You should delete the file FIXLIST.txt

You may delete the tools I had you download.

 

Safer 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".
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.

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).

 

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"

 

Sincerely,

Maurice
