Attempt to scan ports

What kind of FW? If the FW/packet filter is blocking the scans, then why are you worried about it?

So, you lost some disk space. BFD.

Now, you can use, in no order of importance,

Unplug your system from the internet. Anything you try to do to the offending ip address could get YOU into trouble.

Other option is to email reason/log to the machine owner and/or the Internet Service Provider.

Obviously you have some network settings screwed so that the answers for the requests (your browser wants to display a website containing images fro us.i1.yimg.com) are not getting through.

Or the scan is from a spoofed source.

However, responding to every port scan is a complete waste of time. Just ignore it, they're nothing you can do anything about, and consider yourself lucky that it's not more than a little tickle and that you're loggin them...

Well, one thing you can do is ignore it. If you don't have services listening on those ports there's nothing to get worked up about.

That's good advice -- I recently had a client port scanned as part of a VA, they were upset that I didn't alert them when it happened. I showed them however that the entire scan added perhaps 5% to their normal incoming scan volume -- a click in the noise, so to speak. That's just the reality of Internet access. Dump them and move on.

If I remember correctly 'us.i1.yimg.com' is associated with displaying content for Yahoo!

What a surprise that "yimg" means "Yahoo Images", commonly used for both Yahoo website contents and ads.

To you it probably wasn't. However the OP probably wasn't aware.
