Virus bloqueia de executar regedit, msconfig, e arquivos do Windows Installer.

[zani123]

Preciso de ajuda urgente (eu uso Windows XP - Home Edition [SP3]):

Recentemente peguei um vírus chamado AutoIt:Injector-A (pelo Avast), ou Crypt (pelo MalwareBytes).

Quando eu fui no Iniciar>Executar>msconfig, não deu certo, aí deu um erro do Windows.. também tentei: Iniciar>Executar>regedit , e também não deu certo... da esse erro do Windows:
 



(Esse erro também aparece até quando eu executo um arquivo de extensão .REG)

E, quando acusou esse vírus "AutoIt: Injector-A [trj]", acusou vírus no arquivo na pasta C:/WINDOWS/system32/ system.exe

Aí, deletei esse " system.exe" (tem espaço antes do system.exe)... aí, acho que foi por isso que parou de funcionar o Windows Installer, msconfig, regedit. Mas também, o vírus bloqueou.. há algum jeito de tirar esse vírus? POR FAVOR, AJUDEM URGENTE!

Alguém tem uma solução, pra recupera isso pelo menos? Ou pra voltar ao normal? Ja usei o ComboFix, o MalwareBytes, e não deu certo... vai aí o log do HijackThis:
