Internet access is blocked due to malware infection, how to eliminate it?
This tutorial describes how to re-establish Internet access if blocked by malware. Some malware variants modify Internet browser settings by adding a Proxy Server. In these cases, you will be unable to visit any websites, and thus not able to download the required software to eliminate the security infections. Other types of malware change the computer's DNS settings or add various entries to your operating system's Hosts file. By altering these settings, computer viruses can cause redirect issues or completely block the Internet connection. If you cannot access the Internet, and suspect that this is caused by a virus infection, check the settings below.
What is AMBA?
AMBA is ransomware-type virus that targets Russian websites. After infiltrating the server, AMBA encrypts most files on the system and adds the .AMBA or .RROD extension to the name of each encrypted file. A text file ("ПРОЧТИ_МЕНЯ.txt") is then created that contains a message (in Russian) encouraging server owners to contact cyber criminals via the email address provided.
What is Petya?
Petya is ransomware distributed via malicious e-mails containing Dropbox download links to applications which, when executed, will install Petya on victims' computers. Research shows that these e-mails mainly target human resources (HR) departments of various German companies. After system infiltration, Petya encrypts portions of hard drives and makes ransom demands.
What is KimcilWare?
KimcilWare ransomware targets websites using the Magento e-commerce platform (currently, it is not confirmed whether KimcilWare infects other platforms). During encryption, this ransomware adds a .kimcilware to each file stored on the server. Furthermore, it creates an index.html file containing a ransom-demanding message.
KeRanger ransomware removal instructions
What is KeRanger?
KeRanger is ransomware-type malware that stealthily infiltrates systems and then encrypts stored files. Distributed via the Transmission BitTorrent client, KeRanger is the first ransomware that successfully works on the Mac OSX operating system. The software is open-source and, therefore, cyber criminals have edited the source code and concealed KeRanger ransomware within. Once infiltrated, KeRanger remains silent for three days and only then starts encrypting files. To encrypt, cyber criminals employ 2048-bit RSA encryption and, therefore, a private key is required to decrypt all files affected by KeRanger. Note that this ransomware adds an ".encrypted" extension to each encrypted file. Following successful encryption, KeRanger demands a ransom payment from victims in exchange for decryption software. If the user declines to do so, files affected by this malware will remain encrypted forever.
