Ransomware has been a major problem for the last 4 years. It is challenging to realize a more damaging virus for both individuals and businesses. The algorithms utilized in Ransom:Win32/Genasom!a (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy currently exists, and possibly will exist. However, that virus does not do all these horrible things without delay – it can require up to several hours to cipher all of your files. Hence, seeing the Ransom:Win32/Genasom!a detection is a clear signal that you have to begin the removal process.

Where did I get the Ransom:Win32/Genasom!a?

Ordinary tactics of Ransom:Win32/Genasom!a 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 emails and hacktools. Bait emails are a relatively modern tactic in malware spreading – you receive the e-mail that mimics some standard notifications about shipments or bank service conditions changes. Within the email, there is a corrupted MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks quite simple, but still demands tons of attention. Malware can hide in different places, and it is much better to prevent it even before it gets into your system than to depend on an anti-malware program. Basic cybersecurity knowledge is just an important item in the modern-day world, even if your interaction with a computer stays on YouTube videos. That can keep you a great deal of money and time which you would certainly spend while trying to find a solution.
