Antivirus: will these programs are really reliable?

If the antivirus doesn’t work, why keep using?

Historically, companies rely on the “powerful” anti-virus software to help detect, prevent and remove malicious programs before they become a problem.

But, an antivirus alone isn’t enough to stop keyloggers, backdoors, rootkits, Trojans, worms and spywares, increasingly sophisticated.

“Of course that traditional solutions anti-malware signature-based are increasingly ineffective,” says Neil MacDonald, analyst. So why do companies still use it?

There are several reasons why the antivirus is still deployed in enterprise desktops. The first is due to the fact that the antivirus is required by legal necessities and compliance.

As Adrian Sanabria, senior analyst, Enterprise Security Practice, “regulated businesses simply have no choice, because the standard requires the use of antivirus. Otherwise would be considered irresponsible, making them face problems like lawsuits and problems with theft sensitive information, for example”. Second, although the antivirus does not identify all types of viruses still provides some level of protection.

Antivirus are needed, “because there are so many malware out there,” says IDC analyst Charles Kolodgy. “Microsoft has done studies to show that computers without antivirus has a much higher rate of infestation, compared with those using some protection”.

If a lay user without antivirus to browse the Internet normally for a week, have a high probability of having your computer infected with malware, which could be easily identified if it had a security software.

How are traditional antivirus vendors adapting?

The key issue is to understand what will be done going forward to make most efficient products to combat these threats.

“I don’t think we should rely only on antivirus”, adds Kolodgy. “After all, there are few efficient virus, but they are not what most people expect”.

Although much of the change in the antivirus market is being driven by newcomers, providers already established, such as Symantec, McAfee, Kaspersky, BitDefender, Sophos and Trend Micro are not stopped.

With an antivirus, your computer is protected… Really?

Traditional antivirus developers are working very hard to incorporate advanced security technology in their products. The challenge for suppliers is to incorporate the changes in your existing code base and make it functional.

So, what are our alternatives?

We split the antivirus market into three main categories: traditional, seasons protection and incident response.

Traditional antivirus can’t keep the “bad guys” out, ‘cause they have access to traditional library of common antivirus. They just make sure that the antivirus will not identify your programming code before releasing it on the Internet.

Protection products on workstations are more effective in stopping malware, but for the most part aren’t as good at removing them and therefore shouldn’t replace traditional antivirus.

Similarly, products with focus in response to incidents are not effective remediation and are therefore intended only to further antivirus offers.

We conclude then…

Well folks, by sight, the antivirus isn’t a guarantee that the system will be fully shielded from attack. So we have to keep in mind that when we installed an anti-virus aren’t completely free of attacks, only less susceptible to them.

Next posts, we’ll have more details on security, so you can know how to protect themselves properly. See you on Satuday!
