it means that bla trojan tries to attack you, but norton takes care of that thing every time it appears. if you're concerned of your computer security, you can also run anti spyware scan just to be sure everything's fine. i recommend spyware doctor for anti spyware: http://www.2-spyware.com/review-spyware-...

It appears to be fairly harmless, but nonetheless, you need to remove it. Here are instructions describing what it is and what you need to do to remove it:

it means you have a trojan horse

which is a form of a virus

it will try to do something harmful to your computer.

if you got norton, it wont let connect to the person who made the virus so they could not see what your doing.

go to the norton virus web page to see how to get rid of it before it gets worse though.
Don't worry, it says it was blocked, just be glad that Norton can block it!
i prefare dont use norton use other anti trojan as Kasper Sky
Some times Anti-virus software can only remove viruses by working in the safe mode. That means they can temporarily prevent it from attacking your computer until you turn it off and start it up again. If the message occurred only once after boot up, then Norton did it's job and blocked a virus. If it occurred on the next boot up again, you may have a virus Norton couldn't get.
