Windows 7 - can't upload files in Windows 7

I only have Avira Antivir, but i already tried disabling it.... and also in safe mode it doesn't start.

I use NOD32 and have the same problem. I can upload files less than about half a meg anywhere but anything over that and they fail - these are uploads of files, pictures (eBay, Facebook, Twitpic etc), or anything that goes through a browser - same problem on IE8, Firefox 3.6 etc.

I disabled NOD32 and it made no difference too. Even an upload via www.speedtest.net fails!

Update - I've resolved the issue. If you right-click your NOD32 icon in the system tray and select "Advanced Settings", then uncheck "Enable HTTP checking" in "Advanced Setup -> Web access protection -> HTTP, HTTPS" - issue has gone away.

The same sort of rule may apply to other AV / Firewall products?

I have more or less the same problem but i am not using NOD32 at all.
Last time i want to upload an attachment with Google Mail, the Upload failed at all.
Screen snapshot tools with auto upload function to to the web don´t work anymore.
Any final solution for this? Havent had any problems with Windows 7 for "ages".

If it worked previously, and it doesn't work now, I would start by checking your system for any type of virus/trojan/malware. If it is clean, then I would look at the security software you have installed to see if anything has changed in the settings.

Can you upload any files to any website?

Nope, i wasnt able to upload. Neither a snapshot with my snapshot-tool nor any otherfile and here is WHY:

In Google Chrome i set individual proxy settings which (now fasten seatbelts!) were used by Firefox ! even though i chose NOT to use any proxy settings in Firefox. These
system-wide proxy settings were used by Google Mail etc. and any other tool i am using. Sounds dull, but this is the solution: Disable any proxy in any tool thats using proxy and u are all set. Hope this was of any help.
