So my mom was on Best Buy.com at the legit website and a popup/scam attempt popped up, she called me to come look at it and its one that I have never seen before. 

 

There was a popup from chrome (or designed to look like the one from chrome) that was warning about the computer being infected blah blah and to call a number for service to take control and fix the computer (lol no thanks) but the interesting part is it completely locked up the computer and wouldn't allow me to close chrome or take any other action.  I ctrl+alt deleted to shut down chrome and ran a scan on her computers mcaffe security program which came back clear ( the comp is like 2 days old).  

 

Just wondering if anyone else has encountered this particular scam or (if by some small chance) the newer versions of mcaffee actually have a feature to lock the computer like this to prevent you from causing further harm?  I mean Im like 99% it was a clever scam and complete bs but was looking to see if anyone else has run into this dilemma.

Check to see what chrome extensions you have. List them here if you would like and people will help you. Does it happen in any other web browsers? If not, it might be a browser extension

The only extension on the chrome browser is ad-blocker.  I'm not sure if it happens in any other browsers because I'm thinking she just happened upon a scam attempt and haven't attempted to reproduce it....

Welcome to BC...

 

Usually just closing the browser removes the ad. It is a good idea to run some scans to be sure some adware or malware isn't responsible.

Another suggestion is install an ad blocker if you haven't done that and block 3rd party aka ad/ tracking cookies from installing.

Assuming it is the Chrome browser....Adblock Plus - Chrome Web Store

How to disable third-party cookies in all major web browsers

 

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars....especially Google.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

CCleaner - PC Optimization and Cleaning - Free Download

 

Download Malwarebytes' Anti-Malware from Here

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).

  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • When MBAM is finished scanning it will display a screen that displays any malware that it has detected.
  • Click the Remove Selected button.
  • MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.

POST THE LOG FOR  REVIEW.

 

Download AdwCleaner by Xplode onto your desktop.

  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Scan button.
  • When the scan has finished click on Clean button.
  • Your computer will be rebooted automatically. A text file will open after the restart.
  • Please post the contents of that logfile with your next reply.
  • You can find the logfile at C:\AdwCleaner[S1].txt as well.
  • download Junkware Removal Tool to your desktop.
  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message

Buddy215 gave some really good instructions. Also, what ad blocker are you using? Adblock and Adblock plus are legit but I don't know of any others. Anyway, follow buddy 215's instructions first and see where that takes you. If it doesn't work, tell me what Adblocker you use

I am familiar with all those programs and was in the process of downloading them as I asked this question.  

 

I was basically just wondering if anyone had seen/heard of a popup like this locking up the computer and preventing the browser from being closed.  I have run all the necessary programs and the comp is fine.

I have heard of these. Some actually force your browser to full screen and freeze the computer and display a fake blue screen. They are way more common than most people would like.

Hello...

 

You may want to check if your Adblocker is legit, just in case you have downloaded the fake version.
