Free Software Tests for Bot Infections

PineApp has released a free zombie test that can instantly discover whether an organization’s computer network might be an unwitting spamming machine — a “zombie” or “bot” — that can send thousands of infected spam messages to other networks—without its knowledge.

As a global provider of appliance-based solutions for email and network security, PineApp Corporation ( has created the free diagnostic tool—Zombie Detection System™ (ZDS™)—to determine if a network is infected. Organizations can simply go to, enter the IP address and get an instant analysis.

2 more kitty (storm worm) gone undetected by many scanner

I received similar email last week where 15 out of 32 malware scanners will detect or trigger an alert if found or being downloaded in the system.

Today, I got 2 more kitty greetings.  Result is 10 out of 32 scanners will detect or trigger an alert:





Preview of emails:



Whenever I send file to I always let them distribute the sample to AV companies so they can add it to their detection.  Let’s hope those will be detected soon as it is out-there.

Users need to make sure they are patched, they have the security tool configured to get the updates automatically and most important do not click on anything.

Which Antivirus is right for you?

Which Antivirus is right for you?

Chances are that if you have spent any time in a forum or newsgroup, you invariable saw this question posted “Which is the best Anti-Virus (AV) program?” If not, I am sure you have wondered it to yourself.

The quick answer is always “the one you use”, since using an inferior one is better than not using one. In addition, simply having an antivirus program does not mean you are using it. I can’t tell you how many people say, “Yes, I have an antivirus program, it came with the computer” (and they assumed that meant they were protected!)

Determining which is the best, however, isn’t a straight forward answer. It depends upon a number of factors, any of which may, or may not, be important to you. Some use less memory, some are inherently popular with broad name recognition, some come highly recommended by your friends, some provide very fast updates and some have good support. The truth of the matter is, most AV Programs will catch most of the viruses most of the time (I said most, not all). The choice then boils down to personal preferences.

So which anti-virus is right for you? It depends on your individual needs or requirements. It doesn’t matter whether the anti-virus is freeware or the most expensive anti-virus. What matters most is if you are satisfied with the features, functions and will be able to protect you against any type of malicious code in the wild.

Some features to be aware of are:

  • Some AV Programs will scan incoming and outgoing e-mails while it is being up or downloaded
  • Other AV Programs add a certification to the e-mail which states that their e-mails where scanned by an anti-virus (offering recipients a sense of security and the AV Program gets a little free advertising!).
  • Most AV programs automatically provide daily updates. Others are weekly.
  • Others are offering their AV as stand-alone AV program while others bundles the AV with firewall software. This is called Internet Security Suite.

Most AV Programs that charge will provide a free trial period. Take advantage of this trial offers by trying their product before paying for the program. These ‘pay’ programs usually charge twice (or maybe even three) times.

  • First, they may charge you to purchase the program.
  • Next they will charge you a nominal annual subscription fee. This fee allows you to access the ever growing list of new virus ‘definitions’. This list is usually updated weekly, but many offer daily updates.
  • Finally, some may charge you for technical support. I would not dismiss any AV company simply because they charge a fee. A friend of mine had the technical support people walk him through a problem and his computer was fixed within an hour. Going with a free program will save you money, but ask yourself the following question “Who do I call if something goes wrong?” Think of the fee as insurance!

Always check the system requirements before installing an AV, or any other, program, for that matter!). Make sure your system meets the requirements. Make sure your e-mail program is supported by your chosen antivirus program. This is the most important, since e-mail and viruses go hand in hand!

Once you have decided on a particular program, and you’ve installed the program, the first thing you need to do is check for updates. Programs are written and many months may pass before you install the program. In the virus community, days are considered a long time, weeks an eternity and months…well you get the point!. Next, run a manual scan. See how the program works. Assuming the scan returns a clean bill of health, try launching applications on your system. Observe if anything is acting strange. There could be a conflict between the AV Program and your installed programs. If so, you should alert the respective vendors. They will create a new patch or, if the issue is known, they will provide you a patch.

You should check that the AV Program has a certification or passed an independent antivirus laboratory test. Certified products means that it was tested if the product can reduce security risks caused by viruses and other malware. You might say … “my antivirus didn’t pass or was not certified, but it does protect my system! In fact it caught a lot of virus and removed them”. How can you be sure? Ask your antivirus author or vendor why they didn’t pass or didn’t acquire a certificate for that particular Operating System (OS)? You might want to ask them why their anti-virus passed the test on one system but failed on another system. Please note that not all AV Programs pass the test on all Operating Systems. For example, some will pass the test on Windows XP but fail on a Windows ME system, or vice-versa.

In this page, you’ll see list of sites that will inform you which anti-virus are certified. In addition the list shows which AV Programs passed or failed the test on the different OS. Listed here are some freeware antivirus programs and other security tools that you might want to check. Only install one antivirus program.  Two antivirus programs are not better than one.

So in conclusion, if your computer meets the system requirements, you like the features, it is fast in providing updates (which can be important when there are new malicious codes), there are no conflicts with any of your applications, your incoming and outgoing e-mails are being scanned and the anti-virus program is a certified product and tested on the system that you are using, then the AV Program is one to consider.

Is that all? I hope so 🙂
