I think posted a while ago that the new release of vmware5 would pre-empt our planned review.  Combined with the recent reviews on other sites of backup tools I thought this would be an even better idea.

i think antivirus tools are def. worth installing,
BUT
they do consume cpu scanning every file, and i think a case could definitely be made for NOT installing a resident antivirus, and only using an on-demand antivirus tool, providing you are very careful about not executing programs until you scan them.

on the whole though, i definitely feel safer having a resident antivirus and unless one is playing some top of the line game, the lost cpu cycles are a fair price to pay for some increased safety.

some antivirus programs are easier than others to install in a purely ondemand mode; when we get around to our antivirus recommendations this will be one of the criteria we look at.

There is a program called "Offline Explorer" that has a nice way of telling it numeric ranges like this and then it tries to download them all; it might not be able to download the stream for you but maybe it can find it for you.
