Precautions for safe Internet access:
1. Do not arbitrarily add strangers as QQ friends or WeChat friends, and do not casually accept their video or voice chat requests to avoid port attacks or personal privacy disclosure;
2. Don't open links to unknown websites at will, especially links to bad websites. When strangers send links to themselves through QQ, try not to open them;
3. Don't open emails and attachments of unknown origin casually, so as to avoid the equipment being infected with viruses, which will make the equipment unusable or the hard disk formatted;
4. Don't click on suspicious websites or pop up advertisements casually to prevent the browser from being unusable due to malicious attacks, and may also disclose sensitive files on personal terminals;
