Windows buffering downloaded data?

Hi,

I have more than one Windows XP Prof computers connected to a same ADSL
router. Only one computer has this problem while other are working normally.

With this one computer, whenever I start to download a file or watch a video
etc. from the net it takes really long time (many second) before anything
starts to happen.
When I test the network download speed with that computer, first it takes
forever before the test starts to download the data and then itâ€™s suddenly
over and the test results shows that my network speed is something like 55M
(in reality its only 2M).
It seems like the PC is buffering the data coming in and only then, when the
buffer is full (or the connection is closed before the buffer getting full)
the PC uses (reads) the data (show the download dialog or starts to play the
video etc.). With web pages, this problem is not noticeable.

Like I said no problem with the other computer using the same network
connection.

Any ides what is going on? How to fix this?

Do you have an antivirus app intercepting and scanning downloads?

I do have the application for that but not sure if it's set to scanning
downloads. I need to verify that.
I do have the same application on the another PC, though, and it should have
the same settings and It does not have this problem.

Thanks a lot for the tip. This was actually causing it. I have been
experimenting with this feature at some point and forgot all about it.
