Issues With .Net Messenger

I can't log into any net messenger provided services such as MSN and
Hotmail. Due to improper proxy settings or firewalls. When I contacted
my ISP they told me to download anti-spyware for my internet browser as
they thought that hackers were blocking my net messenger programs. I
couldn't download the suggested Microsoft Anti-Spyware because
apparently the security settings wouldn't allow it even though I had
enabled everything to work. I downloaded the .Net Framework-reliant
components because they weren't shown on my security settings. But it
still failed to download because security settings weren't allowing it.
When I try to run MSN Messenger it says that net messenger is not
connected to my Unwired Modem and that there's something wrong with my
proxy settings or firewalls. What would you suggest to resolve this
problem?
