Hi guys i need to know the latest version that still has XP SP1 SUPPORT.
Will 5.0 install on xp sp1?
Or does 4.8?
thanks alot guys
It will install on XP (I can’t recall if there is an SP limitation), though why you are continuing with XP SP1 as a) SP3 has been out for over 18 months and b) windows support for XP SP2 (and you don’t even have that) ended at the end of July. So to continue to get windows security updates you need to have SP3 installed.
By not having your OS fully up to date leaves your system more vulnerable to exploit.
Well… Why don’t you get XP SP3?
It will do more help (correcting exploits) than you can imagine.
I’m not sure version 5 works on it. Most probably yes.
Anyway, version 4.8 support will end soon.
Avast! anti-virus + Windows XP SP1 = Brinks home security + No locks on your doors
Will 5.0 install on xp sp1?
The Short Answer is YES!
avast is compatible with XP SP1 (Tested)

But unless the OP upgrades from SP1 to SP3, he is still open to many security holes. So as suggested in the previous posts, the OP should fix this. But you did answer his/her question by testing, so thank you. 
@ Gargamel360, I like your analogy. ;D
