Where did I get the Win32:Agent-ARCR [Trj]?

Standard ways of Win32:Agent-ARCR [Trj] spreading are common for all other ransomware examples. Those are one-day landing web pages where users are offered to download and install the free program, so-called bait emails and hacktools. Bait emails are a relatively modern tactic in malware distribution – you receive the email that imitates some regular notifications about deliveries or bank service conditions shifts. Within the email, there is an infected MS Office file, or a web 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 fairly easy, but still needs a lot of awareness. Malware can hide in various spots, and it is better to prevent it even before it invades your PC than to trust in an anti-malware program. Basic cybersecurity knowledge is just an important item in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may save you a great deal of money and time which you would certainly spend while trying to find a solution.
