Please help me remove the viruses in my comp. I have kaspersky internet security 2010. it detects a virus, such as worm.win32.autorun.ftp, virus.win32.protector.c, net-worm-win32.kolab.fap. But everytime it tries to execute special procedures rundll box pops out saying error loading basegui.ppl and all operation stops, all other softwares cant be opened saying its not a valid win32 program. My operating system is windows xp, 32 bit, service pack3.
hoping for your urgent reply, thanks in advance!

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

[CODE]begin
ClearHostsFile;
SetAVZGuardStatus(True);
RegKeyIntParamWrite('HKLM','SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer','NoDriveTypeAutoRun', 221);
DelBHO('{DFB852A3-47F8-48C4-A200-58CAB36FD2A2}');
QuarantineFile('C:\WINDOWS\system32\regedit.exe','');
QuarantineFile('c:\windows\msdrv32.exe','');
TerminateProcessByName('c:\windows\msdrv32.exe');
QuarantineFile('c:\documents and settings\donna\av_md.exe','');
TerminateProcessByName('c:\documents and settings\donna\av_md.exe');
QuarantineFile('c:\windows\system32\av_md.exe','');
TerminateProcessByName('c:\windows\system32\av_md.exe');
DeleteFile('c:\windows\system32\av_md.exe');
DeleteFile('c:\documents and settings\donna\av_md.exe');
DeleteFile('c:\windows\msdrv32.exe');
RegKeyParamDel('HKEY_USERS','S-1-5-21-1715567821-2052111302-839522115-1003\Software\Microsoft\Windows\CurrentVersion\Run','av_md');

RegKeyParamDel('HKEY_LOCAL_MACHINE','Software\Microsoft\Windows\CurrentVersion\Run','av_md');
DeleteFile('C:\WINDOWS\system32\regedit.exe');
RegKeyParamDel('HKEY_LOCAL_MACHINE','Software\Microsoft\Windows\CurrentVersion\Run','Regedit32');
DeleteFileMask('%tmp% ','*.* ',true );
BC_ImportDeletedList;
