I was under the impression that more than one anti-virus on your PC causes more problems than anything else, primarily because they conflict and scan at the same time etc...can anyone clarify this. Bear in mind the NTFS partition uses more disk space than say FAT32, yet FAT32 is probably a dying breed. Reason being NTFS gives you more permission options and info and better control.
Im not sure what sort of partition linux uses
Btw Iv'e never seen a pc with more than 1 antivirus installed lol
For file storage I don't think NTFS is a bad thing, but I may be wrong. The only problem is that I think the majority of viruses affect windows platforms and NTFS partitions.
