Grovat is a computer infection that belongs to ransomware category. These threats are introduced to the target computer systems with the help of various deceptive ways, such as fake updates, spam email attachments or hyperlinks, exploit kits, etc.

Once inside, the malware performs a variety of system changes and then looks for databases, documents, pictures, videos and other personal files to encrypt. For that, it is using AES-256 cipher. Grovat virus contacts with its owners via a C&C server,[1] and then delivers a unique identifier along with decryption code designed for each user separately. The attack is then followed by a ransom note which hasn't been changing since the introduction – _readme.txt. In it, hackers explain what happened to victims' files and that they need to pay $980 ransom in Bitcoin, after contacting crooks via or emails.

Grovat ransomware stems from the notorious STOP/Djvu virus family that has been one of the most widespread cryptoviruses worldwide. Thanks to this fact, virus victims can try STOPDecrypter to recover their encrypted files. You can find a download link below for the tool.

Additionally, it removes Shadow Volume Copies to prevent a speedy recovery. Nevertheless, users still might be successful with tools like ShadowExplorer if this process fails. However, Grovat ransomware removal needs to be performed before file recovery attempt, or the data will be encrypted repeatedly.

If you are downloading insecure programs, make sure you scan it with appropriate tools before opening the executable

Third-party websites that distribute illegal software or its cracks are notorious for malware. While it is highly likely that owners of such sites like Pirate Bay or KickAss Torrents did not place malicious software onto their site purposely, there are many other vectors involved in the whole file-sharing scheme, and it makes file torrenting particularly dangerous.

Generally, experts[3] advise staying away from file-sharing sites that host illegal software or its cracks. However, users will always be keen on acquiring a piece of software for free instead of paying. Unfortunately, such actions might cost you much more – loss of all personal files, along with the money.

Nevertheless, if you do visit sites that are not particularly safe, make sure you use some precautionary measures. Employ anti-malware software with real-time scanning feature, along with Firewall, use ad-blocker and scan every executable you download with tools like Virus Total.

Also, make sure you patch your system with the latest security updates, use adequate protection for RDP[4] and all other accounts, use caution when opening spam emails and generally be careful when browsing the net.

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.
