So. I am not experiencing any problems atm with system and prob don't have viruses but i am getting better hdd soon. So i would like to know theoritically would changing hard drive, reinstalling bios and windows get system rid of all viruses or not? If not where else can viruses(and other malware) be?
 
yes if u do a complete format then you will get rid of all viruses and then install a good antivirus.....i personally use avast free edition its awesome i am using for past 3 years and never encountered a virus issue plus it doesn't slows down down the pc.......

I scan with avast kaspersky and microsoft security essentials every month (scanning with one while others uninstalled) and also use mb antimalware.
So i think the system should be virus clean (also i clean reinstall windowses on all my pcs every once in a while ( easiest way to fix any errors. Lol )
But would changing hdd removing bios battery then reinstalling bios and shutting power for some time so nothing is left in ram get rid of all possible malware?

I am asking whether that would in theory get rid of all malware that has ever been made . I am not planning to do it in reality (except for hdd) since i haven't spotted single malware and system runs fine. And i am not paranoid. I love malware actually. I have a pc decicated to playing with different types with different antivirus.Even though i have many viruses there haven't had any bios virus. I do know they are rare. I just woundered what it would take to clean system in worst case scenario. So you say something as simple as that would be enough?

I am mostly using premium versions too. ( i leftout comodo in last post. It didnt work either) i haven't used bitdefender but i'll definately try it too.
But back to topic is there a malware in internet that could suvive what i said above and if yes where could it write itself? (best thing that comes to mind would be a software that remembers your computer, sends info to server tracks you when you go online and redownloads itself. Would something like this be possible? ( and again i am just asking? i am not afraid of it or paranoid))
