Cannot Remove (PUP.Optional.Legacy) - "pdfsearchengine.net"

Recommended Posts

The PUP (Potentially Unwanted Program) has been showing up over the past few days.

When I Quarantine and restart the computer it shows as if the PUP has been deleted. However upon the next scan it reappears.

How can I delete this  "pdfsearchengine.net" for good?

 

Thank you

Thanks for providing the report.  The FRST report does not show a mention of "pdfsearchengine"

and the Chrome browser extensions do not show any extension related to pdfsearch.

It is possible that the pup.optional.legacy is a false positive.

Next time you do a scan with Adwcleaner, I would like for you to remove the tick marks from the left side & only then click the blue Quarantine button.

When prompted, and if offered, allow that item to be made an Exception.

 

also:

Other suggestions, 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 )

Hello. Thank you for your assistance. However, the "pdfsearchengine" still shows up upon scanning as of my last scan this morning.

I tried the things you suggested except for making the item an 'exception'.

It is good to hear back from you.

Before starting this next report,  Close & exit all of your open programs.

 

I would like to have you run a different report tool, so I can review.

Please download and Save this next tool to the DESKTOP ( if possible) or else to the Downloads folder ( so you can get to it easily).
Please note that the results of the following scans are not necessarily indicative of malware on your computer.

RogueKiller Scan

  •  
  • Save the file first,
  • Close any running programs that you started on your own ( if any).

Double-click  RogueKillerx64.exe to run the program.
Follow the prompts. If a browser window opens, close the window.

In the HOME tab, click Start Scan.
Upon completion, a browser window may open. Close this window.
 

Important: Please do not have RogueKiller remove any detected items.

Click the HISTORY tab followed by Scan Reports.
Double-click the scan log. Click Export TXT, enter a filename and save the file to your Desktop.
Please attach the file in your next reply.

Please know, we can do without clicking on the "Quote" button when doing a reply.  This thread is just you and me.

Thanks for the Roguekiller report.  The scan run found 3 files & 2 P U P   on Chrome.   I suggest to remove all those using RogueKiller.

 

Close any of your running programs that have open windows.

Double-click on RogueKillerX64.exe to start the tool.

Click "Start Scan" to begin the analysis.

 

Once the Status box shows "Scan Finished",  check to see that In Files, the 3 files are ticked / marked for removal.  & also in Web browsers, the 2 lines are ticked / marked for removal.

 

click the Delete button.
When the Status box shows "Deleting Finished", click the "Report" button to show the log.

Please attach the file in your next reply.

Start Chrome.   Do a check on search settings in Chrome.

 

On the address bar at the top,  Copy and paste the following   & then tap Enter-key

chrome://settings/searchEngines

 

If you see pdfsearch  there, remove that line.    Click the 3 dots icon at far right & then select Remove from list.

If you see some other entry you do not know of,  remove that too.

Close Chrome when done.

 

Let me know how things are, after all this.

Sincerely.

I have deleted the 5 total files and removed the pdfsearch from the search engine list in chrome.

After running the AdwCleaner scan again there were no issues found with the system.

Thank you for the assistance and see the attached file.

Thanks for the report.  That is very good news.

I did not notice Malwarebytes for Windows installed on this pc.   Lets do install Malwareytes for Windows and then do a scan with it.

 

Install Malwarebytes for Windows so that we can do a scan with it.

See   https://support.malwarebytes.com/docs/DOC-1141

[ 2 ]

Now a scan.

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, 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    ( if any are tagged ).
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.
Then click the Export button at the bottom left.
Then select Text File (*.txt)

Put in a name for that file and remember where the file is created.

Then attach that file with your reply. Thank you.

I actually did have Malwarebytes installed on this PC installed at the time of the scan by the way.

I selected "scan for rootkits" and the latest scan found no issues.

Hi.  Thanks for the scan report.  This is a fine result.

You may delete the RogueKillerX64.exe  file that I had you download.

Is there anything else that you need at this point ?
