Onde posso obter um backup do rundll32.exe para o Vista?

Question

Um vírus infectou meu PC - tenho certeza de que o arquivo rundll32.exe e seu backup foram substituídos.

O que posso esperar se eu estiver certo em afetar rundll32.exe e como posso corrigi-lo sem o backup? Eu tenho o Windows Vista pré-instalado no meu computador para que eu não tenha o disco de instalação - existem backups para rundll32.exe além da pasta x86?

A razão pela qual eu suspeito que meu rundll32.exe é que sempre que eu efetuo login, o processo rundll32.exe tenta abrir dois vírus dos quais eu consegui me livrar. Aqui estão os detalhes da verificação do sfc:

Answer 1

Execute um Verificador de arquivos do sistema, ele substituirá o arquivo por você. Isso funciona para o XP, Vista, Windows 7

.

Use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file. To do this, follow these steps:

Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.

Type the following command, and then press ENTER:

sfc /scannow

The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. XP may ask for the XP installation CD to be inserted.

O seguinte é apenas para o Vista e o W7

To determine which files could not be repaired by the System File Checker tool, follow these steps:

Open an elevated command prompt. Type the following command, and then press ENTER:

findstr /C:"[SR] Cannot repair member file" %windir%\logs\cbs\cbs.log >sfcdetails.txt

Note The Sfcdetails.txt file contains details from every time that the System File Checker tool has been run on the computer. The file includes information about files that were not repaired by the System File Checker tool. Verify the date and time entries to determine the problem files that were found the last time that you ran the System File Checker tool.

Type the following command, and then press ENTER:

edit sfcdetails.txt
