When I try to download files in IE6 I get the usual promts for file location etc. then the File Download dialog shows but the progress bar is already at 100% and the download finishes normally. However it only downloads a fraction of the file. (e.g. 169K of 36Mb file). It seams to happen with all files types (exe, zip, msi, etc) and from all web sites. I have a laptop connected to the same adsl link and it can download ok.
So far I have:
run a full scan of system with Norton Internet Security 2005 - nothing found
run a full scan with Adaware - few tracking cookies removed
Run a full scan with Windows Defender (beta 2) - nothing found
uninstalled IE6 and reinstalled - no affect
Disabled Norton Internet Security - no affect
run sfc /scannow - no affect
Deleted temporary internet file/cookies/history etc. - no affect
Deleted IE index.dat for user - no affect
I am really running out of ideas and need some help urgently.
