I've been using XP for many years and have no complaints about viruses. Moreover, viruses are not created now, but only trojans. and trojans do not get along on old systems; 32 bits is not enough for them to get around))).
seriously, modern malware is always for modern hardware, modern tricks on how to deceive the user, and how to get something out of him. what can you take from the user's xp? Nothing! ))
i use EEEPC 701 with XP sp3 and i have no problems with it
