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 emails are a relatively new method in malware spreading – you get the e-mail that mimics some regular notifications about shippings or bank service conditions modifications. Within the e-mail, there is a corrupted 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 quite simple, but still requires tons of focus. Malware can hide in different spots, and it is far better to stop it even before it invades your PC than to rely upon an anti-malware program. Basic cybersecurity awareness is just an essential item in the modern world, even if your relationship with a PC stays on YouTube videos. That may keep you a lot of time and money which you would certainly spend while looking for a fixing guide.
