Removing the virus without an anti-virus is very difficult, unless you want to do a clean install.
On the other hand, if you have done a clean isntall (no upgrades, and no restore programs), the virus will be gone.
I suggest downloading Malwarebytes
and doing a Full scan.
Now could you please go into a little more detail about your current virus symptoms? If you did a clean install, and you're sure the virus didn't get back on, then maybe the problem is not a virus.
