前两天收到Email，
Antivirus Plus的优惠只要4.99镁
然后找到一张对照表

Antivirus 少了4个功能，
唯一让我比较疑惑的是Social Network Prevention 这个功能，介绍如下
The Social Network Prevention feature of Bitdefender Total Security can prevent
users’ social media accounts from malicious content. Many users see the malicio
us advertisements on Social Media channels and click on them to know more. Total
Security blocks such redirections. It is absent on Antivirus Plus
大意是Total Security 可以阻止社群平台上点击恶意广告后受到的攻击
但具体我不太清楚少了这功能差了多少，虽然挺便宜，但也怕4.99镁没花在刀口上，有大大
能给点意见吗感谢。
