Bait e-mails are a quite new tactic in malware spreading – you get the email that simulates some routine notifications about deliveries or bank service conditions changes. Inside of the email, there is an infected MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

That can keep you a great deal of money and time which you would certainly spend while seeking a solution.
