00:03 Will you walk around the streets
00:05 without a care in the world?
00:07 (Scream)
00:08 If you don't install a security software
00:10 when you are using a computer,
00:12 then your situation
00:13 is the same as walking around the streets
00:15 without a care in the world.
00:16 Our computers are mainly used to receive emails
00:19 and download other software
00:20 or visit other websites.
00:21 At this time,
00:22 the chances of us getting in contact with hackers
00:24 are very high.
00:25 So, as the most basic security software,
00:27 we must have it.
00:28 Another question is that many friends ask
00:30 "Hey, there are so many brands of security software.
00:32 Some are free, some are paid.
00:35 Which security software should I use?"
00:37 Actually, my advice is
00:38 whether there is paid or not,
00:39 the difference is not too big.
00:41 The most important thing is
00:42 we still need a security software.
00:44 Windows Defender
00:45 can replace the security software.
00:47 Those who use Windows 4.0
00:48 I believe everyone has heard of Windows Defender.
00:50 If you have Windows Defender,
00:51 do you still need to install a security software?
00:53 No, you still need a security software.
00:55 Because Windows Defender itself is relatively basic.
00:58 The content of the security software
01:00 includes a wide range of services.
01:02 So we still need a security software.
01:04 Using Apple,
01:08 hackers will not be invaded.
01:09 Even if you use Apple,
01:10 there are still its own loopholes.
01:12 And hackers have also started to develop
01:14 a lot of viruses and hacking skills
01:15 against Apple computers
01:17 in recent years.
01:19 So, in fact,
01:20 no matter what platform we use,
01:22 as long as we have a preventive thinking,
01:24 we install a security software
01:25 and don't download pirated software casually,
01:28 our risk is relatively low.
01:30 Another point,
01:33 many friends have heard of
01:33 a thing called VPN,
01:35 Virtual Private Network.
01:36 When we connect to the Internet,
01:39 many times the content
01:40 of these Internet links
01:41 is not encrypted.
01:43 If it is not encrypted,
01:44 hackers can read these contents
01:47 to know our identity,
01:48 our password,
01:49 and our account name.
01:51 When we transmit data,
01:52 how do we encrypt these data
01:54 to achieve a secure effect?
01:56 We use VPN to encrypt.
01:59 VPN is mainly used to
02:00 overwrite or encrypt our communication.
02:02 It can't be used to prevent
02:04 "Mother of virus".
02:05 In terms of the progress of the times,
02:09 hackers are also working very hard to learn.
02:11 Including scammers,
02:12 they often improve their hacking skills.
02:14 When they are working so hard
02:15 to learn,
02:17 do you think we need to work hard to learn?
02:19 As much as possible,
02:19 learn about the knowledge of Internet security.
02:22 The boss wants to give us family and friends
02:24 to improve the awareness of Internet security.
02:27 In this way,
02:28 we won't be easily
02:29 targeted by hackers.
02:31 Have you learned?
