I know next to nothing about antivirus software (lolmac user).

I'm currently working at a youth hostel getting all their staff/reception/guest computers back in order, making sure that wifi works properly throughout the whole building and all sorts of other boring stuff.

Obviously I've been pushing pretty hard for replacing the reception, back-office and guest computers with one single iPad, but I'm hitting the language barrier or something because bosslady won't go for it.

So now that we're locked into Windows, I was wanting to get FTR's powerpooterusers' opinions on what antivirus software I should shove onto all of the computers. Free is obviously a big plus (avg or avira still the way to go here?), but if there's a consensus that one of the pay ones really is worth paying the cashdollars, I can try to convince the bosslady that the hostel will explode without this investment.

Thankee thankee thankee
