A new dangerous virus called Xollam that uses a complex encryption algorithm has recently been reported by a number of cyber security professionals. Xollam belongs to the infamous ransomware category of computer infections.

Xollam Virus

As one of the latest representatives of this category, the cryptvorius has been programmed to secretly scan the entire system for specific file types and to then encrypt them with a complex algorithm that can usually only be reversed if a special decryption key is used. The files that fall in the grasp of the infection immediately become inaccessible and the victims cannot open or use them with any program. In addition, the malware may change the file extension of the targeted files to some weird new one that cannot be recognized by the system.

The Xollam virus

After encoding everything that is stored on the computer, the Xollam virus generates a ransom note. In it, the Xollam virus basically informs the victims about what has happened to their files and asks them to pay a certain amount of money as ransom.

The ransom is usually requested in Bitcoin and is asked to be sent to a given cryptocurrency wallet in exchange for a decryption key for the locked data. According to the notification, users are requested to strictly follow certain instructions in order to successfully conduct the payment. The crooks may give a short deadline for the ransom payment and may threaten that if you don’t pay the required money on time, they will delete all of your files automatically and will destroy the key that can restore them.

Unfortunately, trusting the criminals and fulfilling their ransom demands is not a guarantee for anything. You may send your money and never receive anything in return. Or, you may receive a key that doesn’t work. Or, the crooks may send you another malware piece instead of the decryption key and may start blackmailing all over you again. Therefore, it is not a very good idea to actually go for this option and pay them with your money. Instead, we suggest you focus on the timely and successful removal of Xollam from your system and then some legitimate alternative methods that may help you recover the files that have been encrypted.

The .Xollam file

In the removal guide below, we have published step-by-step instructions for the removal of the .Xollam file. And there’s an added section with recovery suggestions for the data affected by the .Xollam file encryption.

Giving our guide a try will not cost you anything and is a much safer option both for your data and computer. Besides, once you remove the ransomware from your computer, you will have a clean and safe system to restore your files onto. We need to warn you though, that, as much as we want to give you hope, the full recovery from the ransomware’s attack may not be possible in all the cases.

The reason is that, apart from encrypting your data, infections in this category (Zoqw) may have the ability to launch additional malicious processes which may delete the Shadow Copies of your data that have remained in the system after the encryption. If Xollam has done this, then you may not be able to bring your data back unless you have external backups. If this doesn’t work, you can look at the list of decryptors on our site and see if there are any that may help you as this is another possible way of bringing some of your data back without the need to pay the hackers.
