Does formatting a PC remove all keyloggers, malware, etc.....?

[zami]

Hi everyone!
I was wondering if someone could help me!
here is the thing:
Last week my steam account got hacked. a random guy sent me a link and told me to download an app from that site. I was stupid and did what he told me. after downloading that app I had to run it. and I did that too! once I did that he hacked me and changed the password and the email. he also logged in to my email.

2-3 days later I formatted my PC, and reinstalled windows 7.

So my question is:
Is my PC now clean form all these keyloggers, malware, or whatever I just installed? and is it ready to use?
Is there anything I have to do before I start using the PC? because I don't want to get hacked again!

I heard about someone who got hacked, and he restored his PC to factory new setting, then he got hacked again!

Please help me!

And thank you for your time!

A low level format may work, but it may not.

A better idea is:

Run DOD wipe, then run

fdisk /mbr

That re-writes your master boot record.
(Thus overwriting any boot sector viruses)

then run fdisk to delete all partitions, then
recreate the partitions.

Then start reinstalling you software.

Thank you for the help!

I did already format my PC a week ago!
If I Run DOD wipe, then run fdisk /mbr right no, am I ready to go, or do I have to format the PC and reinstall windows again?

Run DOD;
Run fdisk /mbr
Run fdisk again to delete all partitions
Reinstall windows which will give you the new partitions you need.
