ANTI-US Virus 🔐 (.ANTI-US Files) — How to Remove?

The Anti-us virus falls within the ransomware type of infection. Ransomware of this type encrypts all user’s data on the computer (photos, text files, excel sheets, audio files, videos, etc) and appends its extra extension to every file, creating the read-it.txt text files in each folder which contains the encrypted files.

It is better to prevent, than repair and repent!

Anti-us virus: what is known so far?

☝️ A strictly correct designation for the Anti-us is “a ransomware-type malicious agent”.

Anti-us will add its own .anti-us extension to every file’s title. For instance, an image named “photo.jpg” will be altered to “photo.jpg.anti-us”. Likewise, the Excel file named “table.xlsx” will become “table.xlsx.anti-us”, and so forth.

In each folder with the encoded files, a read-it.txt text file will appear. It is a ransom money memo. It contains information about the ways of contacting the racketeers and some other remarks. The ransom note most probably contains a description of how to buy the decryption tool from the racketeers. That is it.

Anti-us overview:

In the picture below, you can see what a directory with files encrypted by the Anti-us looks like. Each filename has the “.anti-us” extension added to it.

How did my machine catch Anti-us ransomware?

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

Nowadays, there are three most exploited methods for tamperers to have ransomware acting in your digital environment. These are email spam, Trojan introduction and peer-to-peer networks.

If you access your inbox and see letters that look just like notifications from utility services providers, postal agencies like FedEx, web-access providers, and whatnot, but whose mailer is strange to you, beware of opening those letters. They are very likely to have a harmful item enclosed in them. Thus it is even more dangerous to open any attachments that come with emails like these.

Another option for ransom hunters is a Trojan file model. A Trojan is a program that gets into your computer disguised as something else. For instance, you download an installer of some program you want or an update for some program. However, what is unboxed reveals itself a harmful agent that encodes your data. Since the update package can have any title and any icon, you’d better be sure that you can trust the source of the stuff you’re downloading. The best thing is to trust the software companies’ official websites.

As for the peer-to-peer file transfer protocols like torrents or eMule, the danger is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is reasonable to scan the folder containing the downloaded objects with the anti-malware utility as soon as the downloading is done.

How to remove the Anti-us virus?

It is crucial to inform you that besides encrypting your files, the Anti-us virus will most likely deploy Vidar Stealer on your machine to get access to credentials to various accounts (including cryptocurrency wallets). That spyware can derive your credentials from your browser’s auto-filling cardfile.

Often tamperers would decrypt several of your files to prove that they do have the decryption tool. As Anti-us virus is a relatively recent ransomware, security software designers have not yet found a way to reverse its work. Nevertheless, the decoding tools are constantly updated, so the effective countermeasure may soon arrive.

Sure thing, if the hackers do the job of encrypting someone’s critical data, the desperate person will most likely comply with their demands. Despite that, paying to criminals gives no guarantee that you’re getting your files back. It is still risky. After getting the money, the racketeers may deliver a wrong decryption code to the victim. There were reports about malefactors just disappearing after getting the money without even writing back.

The optimal solution against ransomware is to have aan OS restore point or the copies of your critical files in the cloud disk or at least on an external storage. Surely, that might be not enough. Your most important thing could be that one you were working upon when it all happened. Nevertheless, it is something. It is also wise to scan your PC for viruses with the anti-malware utility after the OS restoration.

There are other ransomware products, besides Anti-us, that work similarly. Examples of those are Neqp, Ahgr, Ahtw, and some others. The two major differences between them and the Anti-us are the ransom amount and the method of encryption. The rest is the same: files become encoded, their extensions changed, ransom notes are created in each folder containing encrypted files.

Some lucky people were able to decrypt the blocked files with the help of the free tools provided by anti-ransomware experts. Sometimes the hackers accidentally send the decryption code to the wronged in the ransom readme. Such an epic fail allows the victim to restore the files. But naturally, one should never expect such a chance. Make no mistake, ransomware is a bandits’ instrument to lay their hands on the money of their victims.

How to avert ransomware infiltration?

Anti-us ransomware doesn’t have a endless power, neither does any similar malware.

You can protect your computer from ransomware attack taking three easy steps:

• Never open any emails from unknown senders with strange addresses, or with content that has likely no connection to something you are expecting (how can you win in a money prize draw without participating in it?). In case the email subject is likely something you are waiting for, check all elements of the dubious email with caution. A hoax letter will always contain a mistake.
• Never use cracked or unknown programs. Trojan viruses are often distributed as a part of cracked products, most likely as a “patch” to prevent the license check. But untrusted programs are difficult to distinguish from trustworthy software, as trojans may also have the functionality you seek. Try to find information on this software product on the anti-malware forums, but the optimal way is not to use such programs at all.
• And finally, to be sure about the safety of the objects you downloaded, check them with GridinSoft Anti-Malware. This software will be a powerful defense for your system.
