Infected pc or something else?

Hi there good people!
A few days ago something weird happend to my PC.I got a blue screen out of a sudden and my pc got restarted.
Since than I have no working firewall and antivirus programs .I do not see my Norton internet security icon in the system tray.
I can not launch neither Spybot Search and destroy (it says not a valid win32 application) , nor AVG antispyware(it says connection to service failed).
One other thing. The application ATF cleaner goes off right on I have launched it .So It has become useless since the blue screen.
The worst is that I can not go to any web mail account that I have.After I tried to log on the IE 7 and Opera can not proceed, like I do not have internet connection.(but I have a ping to those web sotes)
Hopefully TOR is working fine and thanks to it I can go to my account here and beg you knowledged guys for help.
Also I can not go into safe mode.I tried.
Is my pc infected?
Is there anything I can do to get things better?
Here is hijackthis log file while I am writing this.
Looking forward for your advices.
Almost forgot to mention that I removed some entries in hijackthis right after I realise what has happed to my pc.I thought that they might be the problem to all that.But after no improvement I tried to restore the entries with no success.I got an error and after it the entries were gone from the backup list in hijackthis.
