I am getting dozens of 404 errors on my site that are requests for gif's with apparently random names, like 4273uaqa.gif and 5pwowlag.gif.

I see that most of them are coming from one user. I assume something is happening in the background on her machine without her knowledge. I assume it's a malware thing on the client.

Has anyone seen this behavior before?

Would love to advise my customer that s/he has an issue. I'd also like to stop getting these 404 reports. :)

This question came from our site for professional and enthusiast programmers.

Could you please post full logs of these requests? It definitely sounds like malware, but it may be attempting things that are far more sinister.
