These questions you mentioned are basically not embarrassing for Tencent computer housekeeper ~
My own laptop, xp, has always been the computer housekeeper of Tencent. Provides XP protection shield function, and opens XP hacker protection system, XP security reinforcement system and XP vulnerability repair system by default.
The housekeeper occupies less resources, as evidenced by the picture.
Created the first function of "management+antivirus" 2 in 1, which has the functions of cloud killing Trojan, computer acceleration, vulnerability repair, real-time protection, network speed protection, computer clinic, application treasure, account treasure and so on. Anyway, I have never been poisoned by browsing websites with many advertisements or risky websites.
At present, the most authoritative software killing test in the world is VB 100, with a killing rate of 100% and a manslaughter rate of 0%. Therefore, the ability to kill software and viruses is very strong, and computer housekeeper is the only one in China who has participated in several times and passed all of them.
I hope my answer is helpful to the landlord.
