What is Ransomware?
Ransomware is a type of malware, or malicious software, that encrypts the user's data and demands payment in exchange for decrypting them. Ransomware has been around since 1989 in some form or another.
The user will be shown instructions on how to pay the ransom using Bitcoin and will most likely get a countdown timer for when their files will be deleted unless they pay up. The ransomware can also monitor the victim's computer activity and even lock out any other programs to make sure that they only focus on paying up.
How Does Ransomware Spread?
Ransomware spreads in a variety of ways, but the most common are as follows:
1) Self-spreading with a victim's help: The ransomware is acquired as part of an attack (either on an individual or on their network), and usually compromises that computer.
2) Compromised sites and downloads: Attackers can compromise websites or download files from them to infect the victim with ransomware.
How Does Gujd Ransomware Work?
Gujd Ransomware works by encrypting the victim's files and then demanding payment in the form of a ransom, or a sum that is usually stated to be much lower than the actual cost of decrypting. This means that if they don't pay up, their computer will not only be encrypted but unusable as well.
If the computer is at all infected with Ransomware or any kind, then you will see an error message that has the "Gujd Ransomware" logo and will need to pay up. The text of these error messages are also changed in that they say something along the lines of "You have been hacked!" or "All your files have been encrypted!", depending on what version of Gujd ransomware you are infected with.
How to Remove Gujd Ransomware
Gujd Ransomware is difficult to remove because it installs itself deep in the victim's system. There are many different versions of this ransomware, so getting rid of it will be slightly different depending on where you live.
First, you want to make sure that Gujd Ransomware is not running anymore - if it is still active then Gujd Ransomware will not allow your computer to turn off or reboot and may even lock your computer down.
Then you want to run a malware scan with your antivirus/antispyware software, delete any corresponding files from the scan (including deleting any registry keys), and disable some system utilities like System Restore and Windows Firewall. Generally speaking, System Restore is always a good thing to have so I recommend you leave it alone, but for the removal of Gujd Ransomware, it will just cause trouble.
With your computer clean of Gujd Ransomware, I would suggest writing down any important files that were encrypted on your computer and then perform a scan with an anti-malware program. This will ensure that there are no traces left behind and that you won't get infected again.
How to Protect My Computer From Ransomware
There are a few things that you can do to protect your computer from ransomware. You should never download files or click on links from unknown sources. You also want to make sure that you have updated your security software and have enabled system protection with your operating system (as I mentioned before).
Another helpful tip is to back up important documents (such as family photos) in an external hard drive or flash drive, just in case something happens to them while they are stored on your computer.
However, the best way to protect yourself against ransomware is by preventing it from happening in the first place. A form of ransomware called CryptoWall 2 used social engineering tactics and scareware-like messages in an attempt at getting unsuspecting people infected.
