Safari can’t show the page because of virus
Hi I think my Mac got some kind of virus after I had downloaded a window 10 file online on Mac but later I deleted it. I could surf some websites but later I couldn’t, even my WiFi was working fine. I tried to update my iOS in the latest version and it has back to normal for 5 miniutes unfortunately. The safari was taking very slow also and couldn’t open a page. So if there is any solution I can do it myself at home? For example, uninstall the Mac back to factory setting? Would it help for sure? If I did, and after I log in my Apple ID on my Mac, will those safari links that I have been saved linked with my Apple ID? so I won’t lose them after uninstall? Thanks. As the apple shop is not opening atm, anywhere I can get help? Thanks
