If you already formatted your laptop those viruses should be gone but if you think you have a rootkit

Scan with this tool called kaspersky anti rootkit TDSSKiller

If you find something delete it.

But just to be extra safe re flash your bios/ update it and then scan afterwards to see if anything pops up.

Do you have pointers on flashing the bios.

Had tried that TDSSKiller earlier.

Yea you can download it from this link and then follow the instructions

thanks, worked like a charm.

So having flashed the BIOS and upgrading it, should I be secure that there is no rootkit inside the machine?

[doubt_me]

Yup.

Just ugh try not downloading random cracked programs and open up any spam emails.
