My computer got infected [again]

A while ago, my dearest machine got infected by a malware. It was about Rockmelt that was lurking in the facebook not long ago. Even for me got fooled by that application which suggests me to download Rockmelt, hiding behind a contact sending message to me and to all my friends.

I didn't even know that my Windows was infected until i managed to update the anti-virus software (I think it was due to that malware, the anti-virus was unable to update properly). What i did was reinstall the anti-virus (Avira Antivir Personal) and update its database. After a few minutes, it detects explorer.exe and winlogon.exe contains TR/Patched.Gen and need to restart the pc to finish the process.

But it didn't stop there. At this point, explorer.exe is unable to load due to restrictions by the anti-virus. But somehow winlogon.exe got through. Since explorer is inactive, i have to look for an alternative to get Windows work again. Using command prompt, i searched for explorer.exe and winlogon.exe and found both backup in C:\WINDOWS\ServicePackFiles\i386\. I copied both files to C:\WINDOWS\. At first, explorer.exe was a success but not to winlogon.exe. In short, this is useless.

 So, i  googled and found a solution: ComboFix.

  • To fix this problem, first, download Combofix here.
  • Disable any anti-virus, script blocking, firewall or any security software.
Warning! Please be advised that if you run this program, there is no turning back. But still, system restore point is always an option. :)

  • Run Combofix. It's better to let explorer.exe unloaded (open Task Manager by pressing Ctrl+Alt+Delete and from Processes tab, look for explorer.exe and click End Process and click Yes upon confirmation).
  • Follow on-screen instructions exactly as instructed. Do NOT multi-task a.k.a open other programs.
  • Let the utility finished until it generates report log file.
There you have it. Another fine solution as a result from googling. :)
