Help me- Network Intrusion detected??

I am getting the following connection request again and again. I think this is some kind of script to hack my computer. I am using OpenSUSE 11.3-64 bit. In previous version and i saw the problem of internet connection on KDE desktop environment. Some body hacks the environment and internet stops working. The interface don’t show the eth0 (ifconfig). The same interface works fine with windows. Initially i thought the problem is with SUSE alone but same problem i found in KUBUNTU( the KDE version of UBUNTU). I am afraid the same problem might occur here again. It is really annoying to install the OS again and without internet there is no use of Computer.

Can any body tell me how to stop this intrusion?

Please help me…

Hi
So what services are you running? The destination port is 46145 and you
say the problem doesn’t exist in windows?

Just a thought, maybe the issue does exist in windows (a virus) and
because it’s working there and won’t work on linux so you see the
events coming in…
