top threats to email securityDespite the many spam and malware filters that were created as ways to ward off top threats to email security, you can still find quite a lot of Trojans and other malware going around the web by way of file attachments and URLs. According to security reports, websites are taking the place of emails as the place where malware thrive but the antivirus company Kaspersky still states that malicious files were detected in emails they scanned on a regular basis. When you want to ensure that your email and your computer system stays safe and malware-free, it pays to know the enemy. Below are the top malware threats that you can get via email.

BredoZp – Bredo is a type of SPAM generated by bots in order to recruit even more bots. For instance, you get mail where BredoZp will pose as a money order notice from a money transfer company. This notice will come with an executable .zip file that has Bredo-A. Once you open the file, it is implanted into a temporary folder in the PC in the form of an auto-run file with a random name. Bredo-S will pose as a DHL or UPS delivery problem notice with a .zip file containing malware programs like Bredo-E, EncPk, FakAV etc.

FakeAV – Reports state that this is the second most prevalent malware that travels by email. In the past year, there has been an influx of FakeAv variants and these make use of scareware that work to exploit the fears of end-users. For example, you get a FakeAV-EI SPAM mail in your folder and it carries a Trojan horse in the form of a 30-day McAfee VirusScan free trial.  This is a common ruse and users who fall for this are then given a warning that their computers are infected and are then urged to buy a clean-up software which is really just another way to infiltrate your computer. If you must know, it is always important to be wary of security programs that come to you through unsolicited mail. Legit security program providers will never do that.

JS Redirector – This is malware that is popular not just on email but also on the web. This is a JavaScript Trojan horse that makes use of generated URLs to direct Internet users to suspect and malicious websites that carry porn or malware, and phish for private information. Some of the ways JS Redirector is spread includes the use of drive-by downloads and it is therefore not surprising that this malware uses HTML-formatted messages to spread via email. Even if you stay clear of suspicious .zip files that are sent to you via mail, it is very possible that you will fall for an HTML message that takes you to a website you never intended to visit in the first place. However, you can inhibit JS Redirector simply by disabling JavaScript execution on your chosen mail client.
