Browser self-launching

Hallo,
I experienced several problems with my laptop (acer aspire 1642lmi, windows xp sp3).
It got slower time by time and recently he probably got some viruses, because teh browser Firefox use to start witout my command opening some commercial pages like "medicatales" or "business news".

I followed your instructions:
Kaspersky healed 4 infections (4 worms win32) and avz and hijack gave the results I'm attaching.
Just for being more detailed, I'm attaching also the log from Kaspersky Virus removal Tool.

There is something more that I can do now?
The browser is still self-launching right now

Thanks!

1. Please, disable System Restore and antivirus (if you have).
2. Execute this script in AVPTool:

[CODE]begin
ClearHostsFile;
SetAVZGuardStatus(True);
RegKeyIntParamWrite('HKLM','SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer','NoDriveTypeAutoRun', 221);
DelBHO('{DFB852A3-47F8-48C4-A200-58CAB36FD2A2}');
DelBHO('{7E853D72-626A-48EC-A868-BA8D5E23E045}');
DelBHO('{5C8B2A36-3DB1-42A4-A3CB-D426709BBFEB}');
DelBHO('{3CA2F312-6F6E-4B53-A66E-4E65E497C8C0}');
QuarantineFile('C:\RECYCLER\S-1-5-21-6470327441-4024922985-252353363-9351\nissan.exe','');
DeleteFile('C:\RECYCLER\S-1-5-21-6470327441-4024922985-252353363-9351\nissan.exe');
BC_ImportDeletedList;
ExecuteSysClean;
ExecuteWizard('TSW', 3, 3, true);
BC_Activate;
RebootWindows(true);
end.[/CODE]
3. After reboot execute this script in AVPTool:

[CODE]begin
ExecuteRepair(13);
CreateQurantineArchive('C:\quarantine.zip');
end.[/CODE]
Upload file C:\quarantine.zip, by link [url]http://virusinfo.info/upload_virus.php?tid=65161[/url]

4. Make a new log of AVPTool.

Thanks, it worked perfectly.
AVPTool didn't find any infection now.
The browser is no more self-launching and the whole system seems to be more stable.
Your help have been very precious!
