What is VirTool:Win32/Injector!EF virus?

VirTool:Win32/Injector!EF is ransomware-type malware. It searches for the documents on your disk drive, encrypts it, and then asks you to pay the ransom for getting the decryption key.

Ransomware has been a headache for the last 4 years. It is challenging to imagine a more dangerous malware for both individual users and companies. The algorithms used in VirTool:Win32/Injector!EF (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy actually exists, and possibly will exist. However, that virus does not do all these terrible things without delay – it can take up to several hours to cipher all of your documents. Therefore, seeing the VirTool:Win32/Injector!EF detection is a clear signal that you need to begin the elimination procedure.

Where did I get the VirTool:Win32/Injector!EF?

Usual methods of VirTool:Win32/Injector!EF spreading are typical for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free software, so-called bait e-mails and hacktools. Bait e-mails are a quite new tactic in malware spreading – you receive the email that imitates some regular notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks quite uncomplicated, but still needs tons of attention. Malware can hide in different spots, and it is much better to stop it even before it gets into your PC than to trust in an anti-malware program. Essential cybersecurity awareness is just an important thing in the modern world, even if your relationship with a PC remains on YouTube videos. That may keep you a great deal of time and money which you would certainly spend while looking for a fix guide.
