Where did I get the Trojan-Ransom.Win32.Convagent?

Common ways of Trojan-Ransom.Win32.Convagent distribution are basic for all other ransomware variants. Those are one-day landing websites where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait e-mails are a quite modern tactic in malware spreading – you get the e-mail that imitates some routine notifications about deliveries or bank service conditions shifts. Inside of the email, there is a corrupted MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

Preventing it looks fairly easy, however, still demands tons of focus. Malware can hide in various places, and it is much better to stop it even before it invades your PC than to depend on an anti-malware program. Essential cybersecurity awareness is just an essential item in the modern-day world, even if your relationship with a computer remains on YouTube videos. That can save you a lot of money and time which you would spend while seeking a solution.
