Jigsaw Ransomware - How to remove?

 

Jigsaw Ransomware is a serious infection that can infiltrate into your system without you noticing, lock your files and try pushing you into paying money. It usually asks around $150 in Bitcoins and claims that this is the only way to get your files back. Clearly if your important files were locked, you will do whatever it takes to get them back. However, if it’s Jigsaw Ransomware, be very careful. Even after paying, there are no guarantees that you will get a decryption key. Therefore, we strongly recommend restoring your files from a back up and removing Jigsaw Ransomware as soon as possible.

It is also recommended to scan your system wit ha reputable anti-malware program, like Spyhunter or StopZilla to make sure your system is clean. These programs will also protect your system from similar infections.

About Jigsaw Ransomware

Once installed, Jigsaw Ransomware scans your system and looks for certain extensions to encrypt your files. Usually it targets files with the following extensions: .gif, .png, .bmp, .pdb, .sql, .php, .asp, .swf, .xml, .ppsm, .asx, .mpg, .wmv, .vob, .m4u, .xlsb, .raw, .png, .java, .jar, .class, .doc, .docx, .ppt, .xpm, .zip, and and others. Then it changes the names of your files and ads .fun extension to them, so they become .gif.fun, .png.fun, etc. Sometimes, other extensions are used as well (.btc, .gws or .kkk). Then Jigsaw Ransomware displays a message that looks like this:

Your computer files have been encrypted. Your photos, videos, documents, etc….
But, don’t worry! I have not deleted them, yet.
You have 24 hours to pay 150 USD in Bitcoins to get the decryption key.
Every hour files will be deleted. Increasing in amount every time.
After 72 hours all that are left will be deleted.
If you do not have bitcoins Google the website localbitcoins.
Purchase 150 American Dollars worth of Bitcoins or .4 BTC. The system will accept either one.
Send to the Bitcoins address specified.
Within two minutes of receiving your payment your computer will receive the decryption key and return to normal.
Try anything funny and the computer has several safety measures to delete your files.
As soon as the payment is received the crypted files will be returned to normal.
Thank you

As you see, it claims that you have 24 hours to pay a ransom or the amount of it will be increased. It also starts deleting your files if you don’t pay within 24 hours. If you don’t do it in 72 hours, the program claims that your files will be deleted for good. It sound really scary, especially if Jigsaw Ransomware locks important data. However, you should not rush to pay, as it doesn’t guarantee that your files will be unlocked. We highly recommend restoring your files from a back up and removing Jigsaw virus.

Note, that if you REBOOT your PC, 1000 files will be deleted at once. Thus if you turned your computer down, don’t boot it without good enough plan.
