Q: restoring default factory settings without itunes as both may have malware

How can I restoring default factory settings without itunes on my ipod 1 and ipod 3rd generation, as both may have malware aswell as 3 laptops, 2 mobile, TV snd BluRay Browser.

any advice will be greatly appreciated.

have tried to disinfect with Kaspersky products but the malware just overwrites everything that is put into the p.c. so I need to use just the pad itself, that is, of course, if it allows me access.

theres nothing like a ipad scorned, ask my weary eyes. cheers
