Erasing a hard drive full of virus from old pc

Solution
1) Plug it in, format it by right clicking and click format.
2) Once erased, scan your whole system with your anti-virus, use Malware-Bytes and Microsoft security essentials.
3) I never suggest using spyware blaster since it doesn't detect all of the virus's, so please use the ones above.
4) Once scanned remove all virus's if there is any and sit back and relax :)
