FUN Virus 🔐 (.FUNNY Files) — How to Remove?

The Fun virus belongs with the ransomware type of infection. A harmful program of such sort encrypts all user’s data on the PC (photos, text files, excel tables, music, videos, etc) and appends its own extension to every file, creating the readme.txt text files in every directory which contains the encrypted files.

Fun virus: what is known so far?

Fun adds its own .funny extension to every file’s name. For instance, an image named “photo.jpg” will be turned into “photo.jpg.funny”. In the same manner, the Excel file named “table.xlsx” will be renamed to “table.xlsx.funny”, and so on.

In each directory that contains the encrypted files, a readme.txt file will be found. It is a ransom money memo. It contains information about the ways of paying the ransom and some other remarks. The ransom note usually contains a description of how to buy the decryption tool from the tamperers. You can get this decryptor after contacting [email protected] by email. That is how they do it.

How did Fun ransomware end up on my PC?

There is a huge number of possible ways of ransomware infiltration.

Nowadays, there are three most popular methods for hackers to have ransomware planted in your digital environment. These are email spam, Trojan infiltration and peer-to-peer file transfer.

• Another thing the hackers might try is a Trojan horse model. A Trojan is an object that infiltrates into your machine pretending to be something else. For instance, you download an installer of some program you need or an update for some service. However, what is unboxed turns out to be a harmful agent that corrupts your data. Since the update wizard can have any title and any icon, you’d better be sure that you can trust the resource of the things you’re downloading. The best way is to use the software companies’ official websites.
• As for the peer-to-peer file transfer protocols like BitTorrent or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. So you’d better be using trustworthy websites. Also, it is a good idea to scan the folder containing the downloaded files with the anti-malware utility as soon as the downloading is done.

How to remove ransomware?

It is important to note that besides encrypting your data, the Fun virus will most likely install Vidar Stealer on your machine to seize your credentials to various accounts (including cryptocurrency wallets). The mentioned program can derive your logins and passwords from your browser’s auto-filling data.

How do I avert ransomware infiltration?

Fun ransomware doesn’t have a superpower, neither does any similar malware.

You can protect your system from its infiltration in several easy steps:

• Never open any letters from unknown senders with strange addresses, or with content that has nothing to do with something you are expecting (how can you win in a money prize draw without even taking part in it?). In case the email subject is more or less something you are waiting for, scrutinize all elements of the dubious letter carefully. A fake letter will surely have mistakes.
• Avoid using cracked or unknown software. Trojans are often spreaded as a part of cracked software, possibly as a “patch” to prevent the license check. Understandably, untrusted programs are very hard to distinguish from reliable software, as trojans may also have the functionality you need. Try searching for information about this software product on the anti-malware message boards, but the optimal way is not to use such software.

Frequently Asked Questions

🤔 How can I open “.funny” files?Is it possible to open“.funny” files?

Negative. That is why ransomware is so frustrating. Until you decode the “.funny” files you will not be able to access them.

🤔 The encrypted files are very important to me. How can I decrypt them quickly?

If the “.funny” files contain some really important information, then you probably have them backed up. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. All other solutions require time.

🤔 What should I do if the Fun virus has blocked my computer and I can’t get the activation key.

🤔 And what should I do now?

Many of the encoded files might still be within your reach

• If you exchanged your important files via email, you could still download them from your online mailbox.
• You may have shared images or videos with your friends or family members. Just ask them to send those pictures back to you.
• If you have initially got any of your files from the Web, you can try to do it again.
• Your messengers, social networks pages, and cloud storage might have all those files as well.
• Maybe you still have the needed files on your old PC, a notebook, phone, flash memory, etc.

HINT: You can employ file recovery programs¹ to retrieve your lost information since ransomware encrypts the copies of your files, removing the original ones. In the video below, you can see how to recover your files with PhotoRec, but be advised: you can do it only after you remove the ransomware itself with an anti-malware program.
