When I try to read my Yahoo Mail, after 5 seconds the page disappears and is replaced by a blank page. Address bar reads "about:blank."  

If I do nothing but observe, after 30 minutes there are 20 tabs open, all of them "about:blank."

Hello @fbram

Let's start off with the following and see if that corrects the issue or helps us to locate the issue.

 

Please run the following steps and post back the logs as an attachment when ready.

STEP 01

  • If you're already running Malwarebytes 3 then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
  • If you don't have Malwarebytes 3 installed yet please download it from here and install it.
  • Once installed then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
  • Once the scan is completed click on the Export Summary button and save the file as a Text file to your desktop or other location you can find, and attach that log on your next reply.
  • If Malwarebytes won't run then please skip to the next step and let me know on your next reply.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

  • Right-click on the program and select RunAsAdmin.jpg Run as Administrator to start the tool.
  • Accept the Terms of use.
  • Wait until the database is updated.
  • Click Scan Now.
  • When finished, please click Clean & Repair.
  • Your PC should reboot now if any items were found.
  • After reboot, a log file will be opened. Copy its content into your next reply.

 

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

  • Double-click to run it. When the tool opens, click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here.
  • Please attach the Additions.txt log to your reply as well.

 

Thanks

Ron

Did you receive the Export Summary?  I received a message indicating that an error ocurred in the transmission.  I am ready to began Step 3, now.

 

I had to reset MWB password twice b/c it was not recognized. Both times I had to go to yahoo mail to follow the instructions  for the reset. Neither time did 

the email disappear. Neither time did a blank page appear nor did "about:blank" begin self-replicating in the addrress bar. Just now, 

I returned to yahoo mail and read two emails and nothing bad happened. I have had  the"about:blank" problem since14:00 this afternoon.  I think I will continue with Step 3 anyway.

This afternoon I did a scan which showed no threats. I also re-started the computer several times. The "about:blank" problem continued.

Timeline:
Friday 14:00-21:00 -Every email I opened on YahooMail was replaced within about 5 seconds by a blank page.  "about:blank" appeared in the address bar. When I deleted the "about:blank," the email I had been reading reappeared, but only for about 5 seconds. It was always replaced by "about:blank." The "about:blank"  slowly self-replicated, filling up  the address bar .  
 
Around 21:00 - In desperation, I decided to seek the help of Malwarebytes. To enter the Forum, I had to reset my password twice. After the first reset, my password still was not recognized. Each time I reset my password, I had to go to  YahooMail to clic on the link. I did not realize  that I was able to do this without the previous interruption from "about:blank." The email from Malwarebytes remained open with no interference from "about:blank" 
 
Although I did not realize it, the problem was resolved. Blind to the resolution of the problem and happy to have a response from MWB, I followed the instructions and did a scan and restart.  
 
This morning, Saturday, everything is working fine. 
 
I do not understand what happened to my computer, but I am very happy to have it working well again.  Thank you for trying to help me.
 
I will follow Step 3 now and send results.

Yes, it's only a single installation but it left 3 entries. Removal of the one should remove all of those entries.

Please go ahead and post the follow-up new logs when ready

Thanks

Chrome cleanup is unfinished. I arrived at Step5 and spent an hour trying to find the prompt to sign out of Chrome.  I never found it.  I am quitting until tomorrow.  

I am sending  the export summary after I deleted the file you suggested.

From the main page of Google.com you can see your logon indicator on the top right portion of the web page. Clicking on the colored icon should show your account as well as a button to log out.

Below is another method you can use to clear Google Chrome settings.

Reset Chrome back to defaults to completely clear out issues with Chrome.

  • Open Chrome and at the top right, click ellipse.png.2829aeeb2aea006bc956de077091and then More tools and then Extensions
  • Write down the list of Extensions installed.
  • Next, go to >> Google Sync << and sign into your account. Make sure you know your password as this will clear it from the browser.
  • Scroll down until you see the  reset_chrome_sync.png "reset sync" button to clear your data from the server and remove your passphrase.
  • Now, close all Chrome windows. Chrome cannot be running for the next step. If needed, print this information or use another browser to read the information.
  • Press the Windows key + R at the same time, to bring up the run dialog box.
     
    • run_command.png
       
  • Type in (or copy/paste) the following and press Enter:     %localappdata%\Google\Chrome\User Data\Default\
  1. Press Ctrl + A to select all the files and folders.
  2. Hold down Ctrl + A and click once on the files "Bookmarks" and "Bookmarks.bak". This will unselect them.
  3. With all the files selected (except for your Bookmarks), press the Delete key and click Yes to delete the files and folders.
  4. Example of all files and folders selected, except Bookmarks

This morning I returned to Chrome, re-activated sinchronization, and repeated all the steps specified by the Belgian girl. I have attached the Summary from the lastest MWB scan.   Do you think the "about.blank"  was the result of a PUP?  I want to save all the instructions you gave me.  

Do you think Firefox is a better choise than Chrome?  I have not used Firefox because I need a program like GoogleTranslator, and also I don''t know how to move LastPass to Firefox.

I greatly appreciate your help during the past three days.  You are a valuable resource!!!

How is the computer running now? @fbram

Is your blank page issue gone now?

Personally I prefer Mozilla Firefox. Google makes most of it's money from advertising and much of that is user metrics,etc.

Let's get real. If you're not backing up your data and you're still using Google Chrome then you're just not serious about Privacy, Safety, and protecting your data. Malwarebytes is a fantastic program but you still need to back up your data and you still need to block scripts and Ads in your browser. 
If you're still using Google Chrome I would highly suggest you consider using Firefox instead. For more advanced users you might consider installing NoScript as well (it does have a higher learning curve though)
