Where did I get the Trojan:Win32/Vundo.RZ?

Those are one-day landing web pages where victims are offered to download the free software, so-called bait e-mails and hacktools. Bait emails are a pretty modern tactic in malware spreading – you get the e-mail that mimics some normal notifications about shipments or bank service conditions updates. 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.

Preventing it looks pretty simple, however, still requires tons of awareness.

Simple cybersecurity awareness is just an essential item in the modern world, even if your interaction with a computer remains on YouTube videos. That can keep you a lot of time and money which you would certainly spend while trying to find a solution.
