How to remove Erop Ransomware and decrypt .erop files

0
Erop is a new ransomware variant derived from the STOP/Djvu family. Malware of such is designed to encrypt users' data and demand victims to pay money for its decryption. Apart from becoming inaccessible after encryption, the targeted files also get altered visually—by receiving the new .erop extension. To illustrate, a file like 1.pdf will change to 1.pdf.erop and become no longer accessible. Once successful encryption gets to a close, Erop generates a text note called _readme.txt which contains decryption guidelines. This ransom note name is quite generic and has been used by other STOP/Djvu variants as well, only with slight variance in cybercriminals' contact information. Inside this note, victims are told it is necessary to purchase specialized decryption software for $980 (or $490 if paid within 72 hours after infection). While establishing e-mail communication with swindlers, victims can also attach 1 encrypted file that contains no valuable information and cybercriminals will decrypt it for free.

How to remove Nigra Ransomware and decrypt .nigra files

0
Nigra is the name of a recently reported file encryptor that is considered to be a variant of Sojusz Ransomware. Cybercriminals behind the successful attack encrypt access to data and then attempt to extort money from victims for the decryption. Files encrypted by this infection will likely be altered according to this pattern [victim's ID>].[cybercriminals' e-mail address] or [victim's ID>].[filename] and the .nigra extension at the end. This means the affected file may appear like this .[9347652d51].[nigra@skiff.com].nigra or else wise. Note that the process of adding new extension to original filenames is only a visual formality and does not change the fact of file encryption in any way. Following complete encryption, the virus will leave a text file with decryption guidelines on a victim's desktop. The text note name by Nigra Ransomware has not been yet publicly disclosed, however, it is likely something same or similar to these examples -----README_WARNING-----.txt, #_README-WARNING_#.TXT, README_WARNING_.txt,!!!HOW_TO_DECRYPT!!!.txt, #HOW_TO_DECRYPT#.txt, #HOW_TO_DECRYPT#.txt.

How to remove Topadvastudio.com

Topadvastudio.com is a deceptive website on which users are tricked into giving permission for push notifications. Although push notifications are a fully legitimate feature allowing various websites to notify users about the latest updates or news, websites like Topadvastudio.com abuse it to deliver untrustworthy and oftentimes unwanted ads. To let the page do it, users are often asked to click on the "Allow" button. Such pages tend to display fake messages saying this action is necessary "Verify that you are not a robot", "Watch the video", "Download the file", and so forth. While clicking on the "Allow" button may sometimes fulfill what the messages claim, the main and undisclosed purpose of this is to simply supply users with unwanted content. Ads generated on users' desktops may therefore contain redirects to rogue and potentially malicious domains, which should not be clicked. If you accidentally became a victim of Topadvastudio.com, make sure you take the necessary steps to remove it. You can use our article for that down below.

Erqw Ransomware is a type of malware that encrypts the victim's files and demands a ransom payment in exchange for the decryption key. It belongs to the family of STOP Ransomware, that started its activity in 2017. This particular version appeared in the beginning of February 2023. The malware typically spreads through phishing emails, malicious software downloads, or exploiting vulnerabilities in the victim's computer or network. Once the malware infects a system, it will encrypt the victim's files and add the .erqw extension to the filenames. The attackers will then demand a ransom payment, often in the form of cryptocurrency, in exchange for the decryption key. Contact details and additional information is disclosed in ransom note file (_readme.txt). It is not recommended to pay the ransom as there is no guarantee that the attackers will actually provide the decryption key. Additionally, paying the ransom supports criminal activities and may make you a target for future attacks. Instead, victims of Erqw Ransomware should focus on removing the malware from their systems and restoring their files from a backup if possible.
