This is a new computer so it should not be a virus, Spyware issues

Downloading Speed and Browsing Speed works fine.

Contracted My Isp and they reply that everything is Normal.

Ok sounds like a firewall or something is causing your packets to drop.

Please specify the following:

ISP:
Type of connection between your PC to the internet - Direct connect to modem
- Wired behind a router
- wireless / behind a router/AP.

Firewall installed on the PC :
Subscribed speed : Check ISP contracts. Counter check by using speedtest.net
Browser : Make and version - I usually go for chrome.
Operating System:

Also try a continuous ping to the site you are uploading to - ei. ping google.com -t

Please post results.
