When I double-click on the BDGandCrabDecryptTool, I say yes, and then nothing, won't openHello,
You indeed have ransomware. Luckily they have a decryptor for you.
Please download the GandCrab Ransomware Decryptor from BitDefender HERE and please follow the directions on the page here.
Please do advise if this works or not. If it does, we will have to do some cleanup and preventative maintenance.
I am running Windows 10 Home 64-bit (10.0, Build 18362). I did run as administrator and still nothing
Your system might be more damaged than I thought. Try to do the following for me.
Please download the FRST 32 bit or FRST 64bit version to suit your operating system. It is important FRST is downloaded to your desktop.
If you are unsure if your operating system is 32 or 64 Bit please go HERE.
Once downloaded right click the FRST desktop icon and select "Run as administrator" from the menu.
If you receive any security warnings, or the User Account Control warning opens at any time whilst using FRST you can safely allow FRST to proceed.
Frst will open with two dialogue boxes, accept the disclaimer.
Accept the default whitelist options,
If the additions.txt options box is not checked please select it.
Then select "Scan"
Frst will take a few minutes to scan your computer, and when finished will produce two log files on your desktop, FRST.txt, and Addition.txt. They will display immediately on the desktop, but can be reopened later as a notepad file.
Please Copy and Paste the contents of these logs in your next post for review by our Security Team
