Hi Mac Elvin

all updates seem to be running just fine now. Updated AVG, Malwarebytes and Windows no problemo


Now subject to no further issues...

Good News! - Your system now appears to be clean. :)
Now for some clean up and "housekeeping" procedures.

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:
  • Download Delfix from here
  • Locate the file and right click on it. Click on Run as Administrator.
  • Ensure Remove disinfection tools is ticked
    Also tick:
  • Create registry backup
  • Purge system restore
  • Reset system settings

  • Click Run

    The program will run for a few moments and then notepad will open with a log. Please paste the log in your next reply.

    Advisory Notes

    Java version is out of date!

    javaicon.gif Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system. Please follow these steps to remove older version of Java components and upgrade the application.

    Upgrade Java : (64 bits)
    • Download the latest version of Java .
    • Click on accept if a prompt for cookies appears.
    • Under the Java SE Downloads, JAVA box, click the "Download" button.
    • Check the box that says: "Accept License Agreement.".
    • Click on the link next to download windows x64 bit (jdk-Nunn-windows-x64.exe) and save it to your desktop.
    • Close any programs you may have running - especially your web browser.

    • Click any item with Java Runtime Environment (JRE or J2SE) in the name.
    • Click the Remove or Change/Remove button.

    • Reboot your computer once all Java components are removed.

  • Alternatively you can download and use a third party defrag program such as defraggler from Piriform. You can download the free version here .

    General housekeeping

    Another essential task is to keep your computer updated with the latest operating system patches and security fixes. Windows Updates are constantly being revised to combat the newest hacks and threats. Microsoft releases security updates that help your computer from becoming vulnerable. It is best if you have these set to download automatically. Follow the instructions below to ensure your settings are optimal.
    1. Click the Start Orb in the lower left corner of the screen.
    2. Type Windows Update in the search box that appears
    3. Click on the Windows Update program that appears in the search results.
    4. Click on Change Settings.
    5. Select "Install updates automatically (recommended)" from the Important updates drop-down.
    6. Choose a day and a time when you know the computer will be on and connected to the internet. The default is 3:00AM every day.
    7. Ensure that all of the other check boxes are checked.
    8. Click OK.

    Malwarebytes - Update and run weekly to keep your system clean.

    Crypto Warning!!!! - Complete Data Loss can occur!

    There are particularly nasty infections out there at the moment that encrypt your data and hold it for ransom. You may read more about this here
  • Download CryptoPrevent free for home use here following the instructions below.
  • Save the file to your desktop from the link above and then open the program by clicking Run when prompted from your browser or by going to the desktop where the file was saved and double-clicking.
  • Accept all the defaults during the install. The last screen of the install has a checkmark in "Launch CryptoPrevent". This is good and will launch the program once you click Finish.
  • You will get a prompt asking if you purchased a Product Key for Automatic Updates. You can answer No.
  • You will then be prompted to learn more about automatic updates or if you want to purchase a key. This is up to you but you don't have to.
  • You will be prompted to click OK to continue and select your protection level. Go ahead and click OK.
  • Click the Apply button to set Default protection.
  • You may get a message stating that Windows Sidebar and Desktop Gadgets are a major security vulnerability and asking you if you want to disable them. If you don't use these features, answer Yes.
    That's it. The protection is in place.

    Note: The free version doesn't provide automatic updates. Periodically, you should open up the program (there is a shortcut on your desktop now) and select the Updates! menu....and select Check for Updates to see if there are any as this infection has serious consequences.

    Prevention advice and tips
  • Watch what you open in your emails. If you get an email from an unknown source with any attached files, do not open it.
  • Install and keep only one anti-virus on your machine. Update it and scan your machine with it at least once a week.
  • Be careful of the websites you visit.
  • When browsing the internet, look closely at the links you click on. Some aren't always what they seem.
  • Avoid Peer to Peer file sharing utilities, these are a minefield of malware infections.
  • Pay attention when installing a program to your computer, particularly to any check boxes that may appear during installation, it is common for unwanted software to be installed in this way.

    To learn more about how to protect yourself while on the internet read this little guide Best security practices.

    Happy safe surfing!! :)

    It's been a pleasure working with you :)

    Please remember to post the Delfix log!

    Many thanks

Bruce - thanks so much for all your help! It's been a life-changing experience.  :thumbsup:


Had to run Delfix twice...didn't realize it didn't save the log file and Crypto rebooted.  :oops:


Oh, and I didn't think you were supposed to defrag SSDs?
