What is Trojan-Ransom.Win32.Blocker.kkoq virus?

Trojan-Ransom.Win32.Blocker.kkoq is ransomware-type malware. It searches for the documents on your computer, ciphers it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this virus also does a ton of harm to your system. It alters the networking setups in order to avoid you from reading the removal manuals or downloading the antivirus. In rare cases, Trojan-Ransom.Win32.Blocker.kkoq can even block the launching of anti-malware programs.

Ransomware has actually been a headache for the last 4 years. It is hard to realize a more damaging malware for both individual users and corporations. The algorithms used in Trojan-Ransom.Win32.Blocker.kkoq (typically, 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. But that virus does not do all these terrible things immediately – it can require up to several hours to cipher all of your documents. Hence, seeing the Trojan-Ransom.Win32.Blocker.kkoq detection is a clear signal that you must start the clearing procedure.

Where did I get the Trojan-Ransom.Win32.Blocker.kkoq?

Standard tactics of Trojan-Ransom.Win32.Blocker.kkoq injection are common for all other ransomware variants. Those are one-day landing websites where users are offered to download the free software, so-called bait emails and hacktools. Bait emails are a pretty new tactic in malware distribution – you receive the email that simulates some standard notifications about shipments or bank service conditions changes. Within the e-mail, there is a malicious MS Office file, or a 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 fairly simple, however, still needs a lot of recognition. Malware can hide in different places, and it is better to stop it even before it invades your PC than to rely upon an anti-malware program. General cybersecurity knowledge is just an essential item in the modern-day world, even if your interaction with a computer stays on YouTube videos. That may save you a lot of money and time which you would certainly spend while looking for a fix guide.
