Windows 10 Crypto Locker News

Windows 10 has arrived, and with it new opportunities for cyber criminals to extort money from innocent people who may be eager to get their free Windows upgrade to Windows 10.

Here are the facts:

• In one of our previous Facebook posts, we talked about a malicious program which encrypts all of your files on your computer with a password. All of your pictures, documents, and other valuable data is unusable in this state, UNLESS you were to pay the ransom to the criminals.

• We cannot put more emphasis upon this, DO NOT PAY THESE CRIMINALS (there is no evidence which proves that it works).

• Unfortunately, there are only a couple of options available to infected computers. These include restoring your computer from backups made previously (if available, this is not the same as a system restore) or completely reinstalling the operating system of your computer (which does not save any files or programs currently installed on your computer).

• A new variant of this malicious program has come out which has been made to look like a Windows 10 upgrade.

• Typically it will come in an email claiming to be from “Microsoft” (it could even say it is from a Microsoft email address) and usually contains a .zip file.

• Microsoft will not email you about your windows 10 upgrade, but rather it will pop up on your computer automatically (if it meets the correct criteria). If you are unsure if the Windows 10 correspondence is legitimate, feel free to contact us for assistance.

Here are 10 tips to protect you from Crypto locker:

1. Back up your files. If you use an external hard drive, don’t leave it connected to your PC unless you are backing up. Alternatively, pay for an online back-up service – but bear in mind you may still be vulnerable if your backed-up files are mapped as a network drive. Check with your provider if you are unsure or give us a call.

2. Create files in the Cloud and upload photos to online accounts like Flickr or Picasa.

3. Switch to a spam- and virus-filtered email service. Google Mail, for example, does not allow you to receive or send executable files (that can install viruses) as email attachments, even if they are hidden in zip files. (It also does not allow you to send them).

4. Don’t go to online porn sites, which are often the source of malware downloads. Take care when clicking on ads; never open Twitter (or other) links and attachments from people you don’t know or trust.

5. Make sure your operating system is up-to-date with the latest security updates.

6. Install the latest versions of your internet browsers and update add-ons such as Java and Adobe Flash. 7. Get reputable anti-virus software and ensure you update it frequently.

8. On Windows 7, double-check that you have set up System Restore points or, if you are using Windows 8, configure it to keep the “file history”.

9. Act quickly. If you do accidentally download a dodgy attachment, bear in mind it is likely to take some time for the encryption to take place. If you immediately shut down and unplug your computer, it is possible for us to destroy the Crypto Locker before all your files have been encrypted – however, you could permanently lose affected files.

10. Encrypt the files you particularly want to keep private, such as documents containing your passwords or personal information, to prevent criminals from reading what’s in them.
