Confirm whether it is really invaded.
First of all, we must confirm whether it is really invaded. The abnormality of the computer is not necessarily an intrusion, but may be caused by other reasons. You can use anti-virus software or security detection tools to scan the computer to see if there are problems such as malicious software or viruses, so as to confirm whether it is really invaded.
Disconnect from the network
If you suspect that the computer has been invaded, you should immediately disconnect the network connection, including wireless network and network cable. This can prevent hackers from continuing to remotely control or upload and download data.
Modify password
If it is determined that the computer has been hacked, the password should be changed immediately, including the passwords of computer accounts, mailboxes, social media, bank cards and other related accounts. At the same time, it is recommended to use strong passwords and modify them regularly.
Clear away traces
After the invasion is confirmed, the traces on the computer should be removed as soon as possible, including deleting suspicious files, uninstalling suspicious software, and clearing web browsing records. At the same time, it is recommended to back up important materials to prevent loss.
Seek professional help
If the above measures can't solve the problem, it is recommended to seek professional help. You can consult computer manufacturers, security companies or network security experts to get more accurate and effective help.
In short, if there are abnormal situations such as computer intrusion, we should take immediate action to avoid causing greater losses. At the same time, we should also attach importance to computer security and strengthen measures such as password security and anti-virus protection.
