Where did I get the MSIL/TrojanDownloader.Agent.LLX?

Those are one-day landing sites where users are offered to download and install the free app, so-called bait e-mails and hacktools. Bait emails are a relatively modern tactic in malware spreading – you receive the email that imitates some regular notifications about shipments or bank service conditions changes. Inside of the e-mail, there is an infected MS Office file, or a web link which leads to the exploit landing site.

Malicious email spam

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

Avoiding it looks quite uncomplicated, however, still needs a lot of focus. Malware can hide in various places, and it is better to prevent it even before it goes into your PC than to depend on an anti-malware program. General cybersecurity awareness is just an essential item in the modern world, even if your interaction with a PC stays on YouTube videos. That may save you a lot of money and time which you would spend while looking for a solution.
