The algorithms used in Win32/AutoRun.Agent.YD (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions.

Where did I get the Win32/AutoRun.Agent.YD?

Routine methods of Win32/AutoRun.Agent.YD injection are basic for all other ransomware examples. Those are one-day landing websites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait e-mails are a relatively new strategy in malware distribution – you receive the e-mail that imitates some routine notifications about shipments or bank service conditions updates. Within the e-mail, there is a corrupted MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

Preventing it looks quite simple, but still needs tons of recognition. Malware can hide in different places, and it is much better to stop it even before it invades your system than to rely upon an anti-malware program. Simple cybersecurity knowledge is just an important item in the modern world, even if your relationship with a computer remains on YouTube videos. That may save you a lot of time and money which you would spend while searching for a fix guide.
