Where did I get the TrojanDropper:Win32/Surldoe!A?
Usual methods of TrojanDropper:Win32/Surldoe!A spreading are usual for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a quite modern method in malware spreading – you get the email that imitates some regular notifications about shippings or bank service conditions updates. Inside of the e-mail, there is a corrupted MS Office file, or a link which leads to the exploit landing site.

Malicious email message. This one tricks you to open the phishing website.
Avoiding it looks quite easy, however, still demands a lot of focus.

Common cybersecurity awareness is just an important item in the modern world, even if your interaction with a PC remains on YouTube videos. That may keep you a lot of money and time which you would certainly spend while looking for a solution.
