Where did I get the Trojan.Win32.Cosmu.bwts?

Those are one-day landing websites where users are offered to download and install the free program, so-called bait emails and hacktools. Bait emails are a quite modern tactic in malware spreading – you get the e-mail that imitates some standard notifications about shipments or bank service conditions shifts. Within the email, there is a malicious 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.

Avoiding it looks pretty simple, but still demands tons of attention. Malware can hide in various spots, and it is better to prevent it even before it invades your system than to rely upon an anti-malware program. General cybersecurity knowledge is just an important thing in the modern-day world, even if your relationship with a computer stays on YouTube videos. That may keep you a lot of money and time which you would certainly spend while searching for a fix guide.
