Adware.Elex.ShrtCln & Chrome


Recommended Posts

Hello @guri    

You mention "until"  Task manager is opened.   Meaning that after a while,  the percentages drop down after a while.

When one starts Task Manager,  one must have patience and allow the system to settle down for at least One Minute.  The measurement displays on Task Manager take a good while to reflect a true readout !   Do not expect accuracy right at the very start.   Let the applet settle down.

If this is your only "issue"  then discount it.

 

The CPU usage can fluctuate depending on all sorts of conditions.  It  ( high cpu usage  at some moment in time) does not mean that there is some kind of "infection".

For example, it can be due to the mix of tasks ( jobs )  and programs in use.   Also, Task manager will MOST Often show at 100%  when first displaying.  You must wait a few minutes for Task Manager to stabilize with real numbers

You need to have patience / allow Task Manager to settle in.  The behavior you describe is not unusual.

Task Manager will settle down in most cases after a while.

The question needing to be asked:  What are you trying to get to ?

IF you are suspecting some kind of infection  - - - >  do scans with Malwarebytes for Windows.

Then, later on, take an inventory of all of the programs on your box that are auto-started with Windows.

See what programs are NOT a absolute-must-have for auto-start.

 

You may  want to review this topic and see if it applies to your system as well.   It takes a while for Task Manager to compute tasks & then refresh the display..

 

.

Try not using Task Manager to make a security judgement on the state of the system.

Question:   When was the last scan done with Malwarebytes for Windows ?

Question :   When was the last scan with McAfee VirusScan   antivirus ?

 

Question:  What was your purpose in using Task Manager ?

The older report did remove Adware.Elex.ShrtCln   which was associated with the Chrome browser.

You need to make Chrome more sturday.

 

Please do the following actions.

[   1   ]

Use Chrome browser   to go to https://www.google.com/settings/chrome/sync and sign into your account.
Scroll down until you see the "reset sync" button and click on the button
At the prompt click on "Ok".

[   2   ]

for Chrome, while Chrome is running:
Press & hold SHIFT+CTRL+Del keys  on keyboard to get menu for clearing browsing data:

Check mark the line  "Browsing history"

Check mark the line "Download history"

Check mark the lined "Cached images and files"
and press Clear Data button  ( in blue )

[   3   ]

After that, make real sure that Chrome is "NOT" set to reload the pages from the last session

Go into the settings menu of Chrome by first clicking  the control icon of Chrome on upper right of the adress bar

Then look deeper in SETTINGS

Make real sure it is "NOT" set to "continue where you left off"

See this article on our Malwarebytes Blog
https://blog.malwarebytes.com/security-world/technology/2019/01/browser-push-notifications-feature-asking-abused/

 

You want to disable the ability of each web browser on this machine from being able to allow "push ads". That means Chrome, Firefox, or Edge browser (on Windows 10), or on Opera.

Scroll down to the tips section "How do I disable them".

[   5   ]

I suggest you install the Malwarebytes Browser guard for Chrome.

To get & install the Malwarebytes Browser Guard extension for Chrome,

 

Open this link in your Chrome   browser: 

https://chrome.google.com/webstore/detail/malwarebytes/ihcjicgdanjaechkgeegckofjjedodee

 

Then proceed with the setup.

 

[   6    ]

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.

Thanks.  I only needed the C01  report.  Adwcleaner found and removed some link history about istartsurf

Overall, that is a very good bottom line result.

.

This machine has McAfee VirusScan .    Please run a can with it.  Let us see what it reports.

and when you reply back,  Let me know what it is that you are looking for.

That is news that I was not aware of.   Lets us then get a fresh new report from Farbar  F R S T report tool.

FRST64 is on the Downloads folder.

 

Run report with FRST64.     Go to the Downloads folder.

Right-click on FRST64 icon and select Run as Administrator to start the tool , and reply YES to allow it to proceed and run.


Approve the Windows UAC prompt on Windows Vista and newer operating systems by clicking on Continue or Yes. 

Click Yes when the* disclaimer* appears in FRST.
The tool may want to update itself - in that case you'll be prompted when the update is completed and ready to use.

Make sure that Addition options is *checked* - the configuration should look exactly like on the screen below (do not mark additional things unless asked).
Press Scan button and wait.

 

image.png.5d47975010636d1d032768cefa8d6625.png

 

 


The tool will produce 2  logfiles on your desktop: FRST.txt , Addition.txt 
Click OK button when it shows up. Close the Notepad windows when they show on screen. The tool saves the files.

Please attach these 2 files to your next reply.

Please do not do any further changes or runs on your own.   I will guide you ( later ) after you provide these fresh reports.

 

Please know I help here as a volunteer.  and that I am not on 24 x 7.

  • AdvancedSetup changed the title to Adware.Elex.ShrtCln & Chrome

Thank you for the fresh reports.   There are a few leftover remaining references to McAfee in the firewall rules that need clean up.  Please a cleanup tool on Mcafee needs to be run.

I see that several log events were made by Windows about the McAfee service on or about 21 May.

We also need to be sure that the Microsoft Windows Defender antivirus is fully enabled.   We will do several steps.  All this calls for patience.

[    1    ]

To fully enable Microsoft Windows Defender antivirus.   

There is one setting in Malwarebytes that needs to be off.   So that the Microsoft Windows Defender is all enabled.   The Premium ( or trial ) protections of Malwarebytes will still be on.

Start Malwarebytes. Click Settings ( gear ) icon. Next, lets make real sure that Malwarebytes does NOT register with Windows Security Center 

Click the Security Tab. Scroll down to 

"Windows Security Center"

Click the selection to the left  for the line "Always register Malwarebytes in the Windows Security Center".

Close Malwarebytes when done.

 

[    2   ]

Get and use the McAfee  Consumer  product Cleanup tool     MCPR

Use the how-to-guide on this McAfee page

https://service.mcafee.com/webcenter/portal/oracle/webcenter/page/scopedMD/s55728c97_466d_4ddb_952d_05484ea932c6/Page29.jspx

 

Follow the section with the title   Method 2: Remove using the McAfee Consumer Product Removal tool (MCPR)

 

[     3    ]     NEXT

This custom script is for  Guri    only / for this machine only.
Close and save any open work files before starting this procedure. 

I am sending a   custom Fix script which is going to be used by the FRST64 tool. They will both work together as a pair.

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

The tool named FRST64.exe   tool    is already on the Downloads folder
Start the Windows Explorer and then, to the Downloads folder.


RIGHT click on  FRST64    and select RUN as Administrator and allow it to proceed.  Reply YES when prompted to allow to run.
  to run the tool. If the tool warns you the version is outdated, please download and run the updated version.
IF Windows prompts you about running this, select YES to allow it to proceed.

IF you get a block message from Windows about this tool......
click line More info information on that screen
and click button Run anyway on next screen.

on the FRSTENGLISH window:
Click the Fix button just once, and wait.

frst-fix.jpg.f6a25291b39a03d418acc9a3b7136900.jpg
 
PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. Lots of patience. This run here should be fairly quick.
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 next reply later, at your next opportunity   

 

Then, after Windows has restarted, and after it has settled back in,  Let me know how things are.

Sincerely.

Fixlist.txt

The FRST custom Fix run is a success & did what was needed.

Windows checks indicate there are no issues as far as integrity of Windows.

Before this, I had you run Adwcleaner.   And the most recent completed scan with Malwarebytes reported no malware present.

Ready to wrap this up ?   Is there something else you need help with ?

To cleanup on the tool I had you use:

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

.

I am glad to have helped you.   I am marking the case for closure.

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 best.  Stay safe.

Sincerely,

Maurice
