Memory Virus

Hi to all.Please help me asap,my machine does not boot and I tried with a bootdisk and it still could not see my hdd.I ran a virus scan,which removes the virus from memory(forgot the software name).It came with an EXEBUG-Hooker virus found on memory.I want to know how to remove it or whether I need to get myself new memory.

TA in advance

Its also known as cmos killer check with symantic and macafee's websites and get a good antivirus program such as the ones mentioned with full updated definitions to remove it.
