No internet access after running Malwarebytes

Recommended Posts

Good afternoon,

After I ran Malwarebytes Premium Trial on my laptop, I cannot connect to the internet. I read the previous reply for the similar problem, which suggests to use an Ethernet cord instead of WIFI. However, I only have WIFI in my apartment.


I downloaded the reporting tools that provided by the previous reply for the similar problem (FSS, MTB, and mb-support- by my cellphone and ran them after I transferred them to my laptop. The reports from these tools are attached as well as the report from Malwarebytes.


Please give me instructions to fix the problem. Thank you very much.

Did you reboot the machine one time?   Please do a RESTART  from the windows Start  menu.

Then be sure to pick Settings ( widows Settings gear icon ) from the Start menu  menu, then to Network and Internet.

and then click on "Show available networks".

Look for your wifi connection / get it reconnected.    It is not uncommon for WIFI connection to go away from time to time.


I note that this machine is running Windows 10 build 1903

Glad to hear that.   Since there had been a lot of different types of items found and removed by Malwarebytes for Windows, allow me to suggest one other scan to double check for adwares.


I  would suggest to download, Save, and then run Malwarebytes ADWCLEANER.

Please close Chrome and all other open web browsers after you have saved the Adwcleaner and before you start Adwcleaner scan.

Adwcleaner  detects factory Preinstalled applications too!


Please download  Malwarebytes AdwCleaner  https://downloads.malwarebytes.com/file/adwcleaner

Be sure to Save the file first, to your system.  Saving to the Downloads folder should be the default on your system.


Go to the folder where you saved Adwcleaner. Double click Adwcleaner  to start it.

At the prompt for license agreement, review and then click on I agree.


You will then see a main screen for Adwcleaner. ( if you do not see it right away, minimized the other open windows, so you can see Adwcleaner).

Then click on Dashboard button.

Click the blue button "Scan Now".


allow it a few minutes to finish the Scan.   Let it remove what it finds.

NOTE:  When it comes to the section "

Pre-installed applications


You can skip that.

Please find and send the Adwcleaner "C" clean report.

In Adwcleaner, click the "Reports" button.  Look at the list of reports for the latest date & type "Clean".

Double Click that line & it will open in Notepad.   Save the file to your system and then Attach that with your reply.


That C clean report will be the one with the most recent Date and time at folder  C:\AdwCleaner\Logs

Thanks.  Keep me advised.

Thank you for the suggestion!

I ran Adwcleaner. The clean report is attached.

Besides, I found that after I reconnected the network, I still cannot get access to some websites, such as my university email.

Then I went to cmd and input "netsh winsock reset" and reboot the computer. After that, the problem is solved.

ok.  I understand you used "netsh winsock reset"

Thanks for the report from Adwcleaner.


I would suggest a free scan with the ESET Online Scanner
Go to https://download.eset.com/com/eset/tools/online_scanner/latest/esetonlinescanner.exe


It will start a download of "esetonlinescanner.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”.

Thank you for asking. Since there are too many files in my laptop, ESET hasn't finished the full scan. 

Currently, it detects one item. After the scan is complete, I'll look into the the report. 

Thanks a lot for your help! I'm really appreciate it!

OK.   Just if at all possible, attach the log-report after the scan hs completed.

I am guessing that when you chose Full scan that there were more than one disc storage involved.

When you reply, also let me know if there is any recurrence of the internet connection issue.

Hello.   I am glad that the connection issue is gone.

This log report is not exactly the one I expected.  However, it did find some adwares, and one crack tool.

We can wrap up this case.  What follows is a cleanup on the tools used.

Delete the Eset download file   esetonlinescanner.exe

Adwcleaner you may keep and run as needed;   to check for adwares.


Backup is your best friend.  Keep backups of your system on a regular basis to offline storage & keep those safe. https://forums.malwarebytes.com/topic/136226-backup-software/

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
Don't 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.

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.

Stay safe.  I wish you all the best.   😎
