Where did I get the Win32:AceCrypter-B [Cryp]?

Typical ways of Win32:AceCrypter-B [Cryp] distribution are standard for all other ransomware examples. Those are one-day landing sites where users are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a pretty modern method in malware distribution – you get the email that imitates some normal notifications about deliveries or bank service conditions changes. Within the e-mail, there is a corrupted MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks pretty simple, however, still demands a lot of recognition. Malware can hide in different spots, and it is much better to prevent it even before it goes into your system than to depend on an anti-malware program. Simple cybersecurity knowledge is just an important item in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may keep you a lot of time and money which you would spend while looking for a fixing guide.
