The Avast ransomware will encrypt your files

You will learn some important information about this new malware, as well as about the specifics of the Ransomware infections, in the paragraphs below. Many readers of this article may have come here to seek assistance on how to remove .Avast from their computers. If you are one of them, we have to inform you that nearly all Ransomware viruses use similar techniques to achieve their objectives. In the first stage of the infection, a complete hard-disk scan is usually performed to locate certain types of preset computer files. Documents, audio and video files, and, in some cases, data files from the system are the usual target. Once it locates them, the harmful software creates an encrypted copy of every single file, and deletes the originals. In the final stage, the virus program displays a pop-up on the user’s computer, with instructions on how to perform a payment in the form of a ransom if the victim wants to regain access to their information.

The .Avast virus

The .Avast virus is rapidly spreading all over the internet. Carriers of the .Avast virus can be various harmless-looking files, email attachments, torrents, ads, and spam.

Detecting an infection such as .Avast, Bpqd, Kqgs however, may be challenging for most security programs, since there will be no file damage after the file encryption process completes. Thus, your anti-malware program is unlikely to warn you that a file-encryption process is happening in the background of the system. This is because, in reality, the encryption is a widely used technique for data protection, and it is usually not expected to cause damage. Used by a Ransomware, however, the encryption can prevent you from opening your personal files by keeping them hostage for a ransom.

The .Avast file extension

The .Avast file extension is a special file extension that will only appear on the files that have been encrypted. The purpose of the .Avast file extension is to make the encrypted files unrecognizable to any program, and thus, make them harder to decrypt.

If your machine has been attacked by .Avast, you should remember that when it comes to Ransomware, nothing is certain. In case you decide to pay the ransom, you are likely to lose your money regardless of whether you manage to recover your files or not. Moreover, the cyber criminals may decide to ask for more money once the initial payment has been made.

Besides, even if you get a decryption key from them, there is a strong possibility that this key may not function as expected, and fail to decrypt the encrypted information. At the same time, proceeding with the payment of the ransom would definitely assist the hacker who blackmails you with continuing to do the same with other web users. Because of all of the above, we always recommend that our readers look for alternatives, and concentrate on how to remove the Ransomware, instead of give their money to some crooks. Of course, if our removal guide below, or the other techniques you may try, turn out to be ineffective, you can always consider paying the ransom as your last possible solution.
