Hi

somehow my laptop got infected with sirefef.N trojan. After about 5 hours of searching i think i have removed it using combofix and few other applications. Unfortunately i cant connect to the internet now. No matter what i try it just wont connect. Other symptoms left by the sirefef.N trojan are also present namely security essientials is not starting with windows, i have to manually start it each time. Also i cant use system restore anymore as i get an error once computer restarts after the system restore process.

What is the remedy?

Go to

C:\Windows\ERDNT\Hiv-backup\erdnt.exe

Right click on it and select run as administrator and click ok

After restore is complete,restart the PC and see if that helped restoring the internet connection.

Thanks for the update.
