Why did my desk suit World of Warcraft suspend the network as soon as it started?

This problem only occurs when you are running Warcraft? If yes, I think there are Trojan horses and other viruses, so I think the landlord should try to reinstall other anti-virus software first (students who have installed Norton anti-virus software before have a similar situation, because anti-virus software can't kill viruses, so in order to prevent the spread, the firewall that comes with him directly disconnects the network actively) and scans it comprehensively. For the choice of antivirus software, I think Jinshan (simple operation) and Kaspersky (strong antivirus) are still used. Because as far as I know, Norton's game version is generally anti-virus, while Bigfoot's shell is not anti-virus software, and 360 is even more nonsense (it is not a joke to sell shoes and kill software). In addition, the landlord should uninstall the firewall installed by himself, because active disconnection is generally the function of firewall, such as Skynet and Cornea, which have similar functions. In short, change the software to completely kill virus, and then use Blizzard Repairer to repair the client. If not, please ask the landlord.
