Writing zeros to harddrive is it advisable?

[rypm]

---

I need assistance on hwo to write zeros to harddrive kay wa na ko kbaw unsa buhaton sa laptop nko.
Bag-o ra naformat nko using OS xp pero after installing all the drivers(from manufacturer's cd), installing avira personal, nidetect daun ug virus ba to d mawa bisan i delete or quarantine. Kept reinstalling the network adapter kay mawala lng kalit internet. Autoshutdown by NT/authority system sad.
Now, i guess writing zero, format, install os will fix this? and what are the steps?
salamat daan
by the way, wala ni gpartition ang hd ani. Iv backed up my files on my usb which im planning to copy kng ayo na & updated na ang AV unta.


----SOLVED---- paki close nlng ko salamat ninyo tanan

Gusto nimo e-completely erase ang disk I think mao na ang style. Other than that, imo cguro nang installer naay virus.

Inig install nimo sa OS kay idelete ang partition unya create partition dayon tapos format unya install OS. Itry lang kung mao japon.

Having a virus after a reformat does not necessarily mean there's a virus in your laptop that is virtually format-proof. It could be the discs or the removable drives you are plugging in to your computer are infected. Even if you do a low level format to your laptop and your removable drives are infected then your low level format is just good as useless

libog lng ko mga sir. Possible ba na naa virus daan sa genuine winxp cd? or manufacturer's driver cd? kay mao ra gyud na ako g butang.

Genuine copy man jud kaha na siya ang imo XP? Asa man na nimo gikan na installer? Dala na sa imo laptop? Try kuni install ra sa Ethernet, Sound and VGA drivers unya ayaw sa insert og mga flash drive unya download Avast unya iupdate iya virus definition unya try og scan balik. or try Malware Scanner.

O dala siya sa laptop sir.
Should i run avast in safe mode and scan after updating?
