There are many risks on internet, but if you have a good antivirus updated , you have reduced the risk of attack. But sometime is better to test if your antivirus program detecs viruses.

I found an interesting site that you can use to test run your antivirus / Antispyware program and check if you are really protected against these risks.
Antivirus researchers has created some test files that antivirus products "detect" as if it were a virus.  On THE ANTI-VIRUS OR ANTI-MALWARE TEST FILE page , you have only to download one of the different test files and see what will happen.
If you antivirus program works in the right way, the antivirus will show a message about a virus found with EICAR as virus description.

Please note the Eicar disclaimer :

Thank goodness this has turned out to be a dud so far.  It did prove to us, once again, how valuable and forward looking our investment in Altiris products has turned out to be  For our part we prepared for this is several ways:

2.  We put a host integrity check on our Sygate clients to put users who did not have the patch in a locked down mode.

3.  We prepared jobs in NS to disable autorun features on USB devices.

4.  Monitored and remediated virus signature levels.

I'm not foolish enough to believe that we aren't immune to attack but at least, perhaps, we made it a little harder for the bad guys.

Of course, our workstation services team insisted that I put all this stuff on CDs, just in case machines needed to be yanked off the network.

Myth  #6 -- Access Control will protect you

Origin

Clearly, enforcement of need-to-know on key assets is a necessary component of managing the risks of confidentiality breaches.  Without access control, you have no hope of protecting the data.  The myth here is that this kind of protection is sufficient.  Given the huge amount of money, time, and attention paid to this aspect of security, you would hope that locking down your information this way would be enough!

What we see

The rates of data loss we see at customer sites indicate that access control privileges, even in the best run shops, are at least a step or two behind the needed state of provisioning to adequately protect data.  Part of that is driven by the complexity of...
