need help with HJT log file after infected by vcodec and reinstall of

I post this message because I has to reinstall win 2000 after an XP upgrade did not succeed. Upon my first connexion to the Internetto download a firewall I had a popup message from windows saying: "STOP! WINDOWS NEEDS IMMEDIATE ATTENTION, windows has detected 55 critical system error … download regfix.exe".

I installed the firewall after downloading it and installed antispywares (lavasoft, microsoft, ewido). Microsoft antipyware told me I had netBIOS messages service on and turned it off > no more messages.

I ran microsoft antispyware / adaware / ewido / avg in safe mode:

* AVG detected and removed some things (Alexa, MRUlist).
* Ewido didn't detect anything
* Adaware didn't detect anything

Because the symptoms were similar, I downloaded and ran the latest version of highjackthis and repeated the procedure given to me by LDtate here:

after that I rebooted. Here is my latest highjackthis log. Can someone tell me if my PC is now clean and safe again ?

Many thanks in adavance.
