Virus Protection & Hosted Spam Filtering

Security is full of assumptions. Organizations think they’re covered, that their networks are safe, systems are updated and that their critical data is protected. In actuality, assumptions are dangerous, taking administrators off their guard while making users complacent. You could even say that assumptions are sinful, causing actions and reactions that put organizations, data and users at risk.

What is Anti-Virus ?

Antivirus, anti-virus, or AV software is computer software used to prevent, detect and remove malicious computer viruses. Most software described as antivirus also works against other types of malware, such as malicious Browser Helper Objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious LSPs, dialers, fraudtools, adware and spyware. Computer security, including protection from social engineering techniques, is commonly offered in products and services of antivirus software companies.

A variety of strategies are typically employed. Signature-based detection involves searching for known patterns of data within executable code. However, it is possible for a computer to be infected with new malware for which no signature is yet known; and malware is often modified to change its signature without affecting functionality. To counter such so-called zero-day threats, heuristics can be used. One type of heuristic approach, generic signatures, can identify variants by looking for slight variations of known malicious code in files. Some antivirus software can also predict what a file will do by running it in a sandbox and analyzing what it does to see if it performs any actions which could be malicious.

The Spam Problem

Email is now a business critical application for many businesses and when their email performs badly, so do they. Ensuring email performance under ever increasing threats from viruses and spam is a key priority.

Email communications have been targeted by viruses and spam sources for a number of years, to the extent that many users struggle to use the medium productively. The aggressive proliferation of phishing mails has only worsened this trend.

MailDefender provides unrivalled email protection from all email borne threats without requiring an
investment in hardware or software, or incurring an ongoing maintenance overhead.

Spam is an unpleasant fact of life for all companies that use email extensively. Leaving end users to struggle with endless unsolicited mails is unproductive and demoralising, but installing a simple filter is no longer enough.

Techniques to generate new forms of spam are highly advanced and proliferate rapidly. In addition, phishing emails, which contain no actual malicious software, are typically designed to lure email users into giving their personal data to fake banking web sites or their PC becoming infected simply by browsing a compromised website.

Battling the Virus Problem

Running anti-virus software in-house, has a high degree of latency in the level of protection provided. Your AV vendor has to identify a new threat, produce an update and make it available so you can download and apply it. This can take up to 24 hours leaving you vulnerable to so-called ‘zero day’ threats.

It will stop any email that contains a virus or that is classified as spam/phishing before it reaches your network.
