×86是个人版，i32是企业版。
先来看你安装的是什么产品的什么版本，还有你的操作系统是什么，再来决定是用哪个进行更新。
如你所说的，那么你的计算机可以使用i32跟x86都可以，只是x86是企业版与个人版适用，而i32只是个人版适用。
病毒定义包只是保证你在使用期间的产品能够及时发现和防御最新的病毒的，并不能够让过期的产品继续使用。如果你使用的是正版产品，可以继续续定，正版产品可以提供在线自动升级，不仅升级病毒定义包还会升级其他功能。如果你想使用盗版产品，那么可以在过期之后在网上查找一个最新的序列号尝试再次激活，这样你又可以正常使用了，但盗版产品在更新时是不可以在线自动更新的。
病毒包是按照以下情况来区分的：
