Problems connecting to msn

[HawkEye1]

problem to connect to MSN. When I launch the software, he said:

We could not connect to Windows Live Messenger. Try again later. To let us try to solve the problem, click Troubleshoot.
Error code: 80048820.
Complete error code: 80048416.

Of course I tried the Troubleshoot button, and the test results, a panel displays attention to file hosts and ports. So, I do make good, and I propose:

Your hosts file contains entries related to MSN, which are likely to disturb the resolution of names. Would you like Windows Live Messenger cleans your hosts?

I click Yes, but I replied:

The troubleshooting tool connections WLM could not indetifier or repair the connection problem. Here are some other resources likely to help you.
- 1 Look for the error code on the site using WLM.
- 2 Install and run the Removal Tool Malicious Software.
- 3 Visit the discussion group WLM.
- 4 Contact customer service.

Warning:
I said that I made a good analysis:

• My antivirus: AntiVir,
• Spybot Search & Destroy,
• Ad-aware,
• AVG Anti-spyware.

(by putting them on course days before).
I also Repair WLM with Add / Remove Programs and then I completely uninstall and reinstall.

the date and time of your PC is correct?

Otherwise, Windows Update works (history of knowledge, he was stuck with me at a time on my old Acer, and the camp had screwed)
