.PPTX Ransomware Removal Guide
What is .PPTX Ransomware?
.PPTX ransomware is a file locking virus that belongs to GlobeImposter family
.PPTX Ransomware - a file locking cyber threat which belongs to the GlobeImposter ransomware family.
.PPTX ransomware is a file locking virus that comes from GlobeImposter ransomware family. The malware can get injected into the machine after users open malicious spam email attachments, visit dangerous sites, use weak passwords for RDP, or fail to patch the installed software on time. PPTX file extension virus uses several encryption algorithms to lock up personal files and generates a unique key that is sent to a remote server controlled by hackers. To receive the access to data, victims are asked to pay $780 in Bitcoin, and all the information on how to do that is provided in READ_ME.txt ransom note that is dropped into every folder on the PC. PPTX virus authors double the price of ransom after two days; users are faced with the dilemma of whether on not to pay, as the ransomware is not decryptable yet.
|Infection||Spam email attachments, dangerous websites, weak RDP, exploits, etc.|
|Removal||Get rid of the virus permanently. Furthermore, use RestoroIntego to detect all damaged objects|
PPTX virus uses unique ciphers such as AES or RSA to lock important documents on the infected computer. However, ciphers used can differ from system to system. Due to this fact, both encryption and decryption keys are very hard to identify even for highly-experienced computer specialists.
The ransom note that hackers produced reads as follows:
Your files are Encrypted!
For data recovery needs decryptor.
How to buy decryptor:
1. Download “Tor Browser” from https://www.torproject.org/ and install it.
2. Open this link In the “Tor Browser”
Note! This link is available via “Tor Browser” only.
Free decryption as guarantee.
Before paying you can send us 2 file for free decryption.
While many users become devastated about .PPTX virus attack, there is no need to pay cybercriminals. Even though files are hard to decrypt, crooks often scam users by promising a decryption tool in exchange for money. However, once the ransom is transferred the criminals might not respond and send no decryptor.
Do not try to perform test decryption either, because crooks might send you an executable which could harm your PC even more. Instead, we recommend completing the .PPTX ransomware removal instead of paying the demanded price. Furthermore, you can try a tool such as RestoroIntego to fix all the damage done by the ransomware.
Another valid reason to remove .PPTX ransomware is that some dangerous computer viruses, including ransomware, can make your computer system vulnerable to other infections. Avoid this type of possibility and get rid of the ransomware virus before it further damages your computer system. After the PPTX virus is removed, you can attempt to recover data using third-party tools, as explained below this article.
Furthermore, we recommend taking care of important data in the future. If you want to make relevant documents reachable only for the owner, that means you, consider storing copies of valuable files on an external device such as USB flash drive or a cloud server. If you choose to use the USB device, make sure that you keep it unplugged from the computer when it is out of usage, and your data will be protected.
.PPTX virus - ransomware which adds the .PPTX appendix to each locked file.
Avoid ransomware attacks by suppressing your curiosity – do not open spam emails!
According to computer technology experts from Virusai.lt, spam messages and their rogue attachments are the most common ransomware distribution source. If you ever notice that you have received a phishing email which came from a questionable sender and the letter itself includes lots of grammar mistakes, you should get rid of such message and especially DO NOT open any attachments clipped to it.
Furthermore, dangerous computer infections can be spread via third-party websites. These pages include P2P networks such as Torrents, eMule, and others. Stay away from these secondary web pages if it is possible. If not, consider purchasing a reliable computer protection tool. Antivirus software will protect your computer automatically, scan your system, and alert if something rogue is trying to get into the PC.

How to prevent from getting ransomware
Protect your privacy – employ a VPN
There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
