I have used AVAST in the past & found it worked. Of course as a user, you have to be vigilant of those pesky bugger viruses, adware & any other creepy crud that wants to will its way onto your machine. It is hard to find websites with program downloads, that don't trick you into clicking another link, because it seems you are clicking the link you intend, but it is actually a camo malware site.
I have Apple too, so when it came time to incorporate iCloud, I was forced to change out XP to Win 7. Being that I needed a antivirus, & Microsoft Essentials was on hand, I opted for it. It seems to do the job for most stuff & as happens at times, if a deeper problem comes up, I come to Bleepingcomputer for help.
It doesn't seem to matter what antivirus is on, it can fail like anything else can, do to chance.
Good luck with XP. I think its days are numbered & the apocalypse will be fought on that OS as time goes on. Like a rat on a sinking ship, I would choose to jump, when the jumping is good; not when you're overhead, with cement shoes.
