Why not install double antivirus because there will be a virus, which will cause the system to react too slowly? There are four reasons for unloading Maifeite. First, 360 knows more about how long it took home users in China. Second, 360 has never been broken by a virus. Third, 360 has many convenient tools, such as booting to speed up game optimization and so on. Fourthly, if foreign goods are used, the tanks entering China tomorrow will be funded by you. Hehe, conscience, 360 is really good.
