Can't Install Antivirus

My antivirus, Mcafee, recently vanished! I'm completely vulnerable right now. Worst of all, I can't install a new antivirus. It always end up with an error.

I have fixed minor problems on my own but I'm completely stumped with this one. I desperately need help. Don't know what to do.

Symptoms:

1- Mcafee antivirus stopped. The shortcut in desktop points to nowhere. The exe file simply vanished!

What I tried:

1. Tried to reinstall those programs - Failed!

2. Tried to install the last version of those programs - Failed!
"Local machine: installation failed
Installation:
Error: Action failed for file avgamsvr.exe: creating file....
No such file or directory"

3. Tried to install Norton antivirus - Failed!
"Extraction failed - Can not open the output file"

4. Tried to install those programs in safe mode.

a) Tried F8 method - Failed!
It simply stops and starts booting again, but in normal mode.

b) Msconfig method: apparently works. But it doesn’t let me install any of the programs above, anyway!

5. Tried to use windows restore feature - Doesn't work! No matter the restoration point I choose it says it made no changes, and doesn't


I found a related post in this forum and it's located here: http://forums.majorgeeks.com/showthread.php?t=135759. We pretty much have the same symptoms. He found a solution for his problem. I hope I'll find mine.

So what should I do. I would really appreciate it any help I can get. :cry

Thanks. I'll try your suggestions.

 

I tried to post my logs in the thread I linked but I cant. It says I don't have enough privileges. Can anyone help here. I'll attach my log from Hijack This. I'm totally clueless on how to interpret this log.
