Why does the captcha appear every time I get on Q but I can t find the virus?

If the verification code appears on Q, someone else may have logged in to your number. But it doesn't have to be poisoned on your home computer. You'd better ** a 360 safe just in case. If your computer isn't poisonous. All you need to do is log in 15 times in a row. The captcha is gone.

1. You may have used some unofficial software to log in to QQ, or you have hung up on **, or logged in to Q in some unsafe places, such as Internet cafes with unsafe factors. 3. The reason for the existence of virus Trojans in your computer, such as sending some virus messages or deceptive messages when you are infected by a virus, are caused by viruses. 4. Sending QQ messages maliciously, being reported by others, and forcibly deleting a large number of friends.

5. At the same time, please do not provide the password during the time period of your login number so that your friends can log in elsewhere to try yours, it may also be caused by network problems, such as using **, the network is unstable, and it will appear. Solution: Please use antivirus software to fully kill your computer in safe mode, it is recommended that you clear the local chat history of this number (search for the folder named with the number in the QQ installation directory to delete!).

In between, please uninstall all previous QQ versions, **the latest official QQ version to use. There is also the reported QQ number, please be patient and wait for the passage of the observation time, and when the time passes, the verification code will disappear, but you need to re-operate it like the above. The solution to the requirement to enter a verification code for the existence of a double main number in the user's number Due to the recent discovery that a large number of numbers have a double main number (that is, two people know that the number password is used at different times and places at the same time), it is not easy to be discovered by the original number owner, so we have launched a verification code to attract the attention of the real number owner and reduce the loss of the original owner.

1. Sending advertising messages: That is, they may be used by others to send advertisements or fraudulent messages without your knowledge, which will be detected by the system. 2. Remote login:

That is, your number often logs in in one place, and when it is suddenly detected that the login location has changed, a verification code will be added for security purposes 3. The number has hang-up behavior: Usually the number thief will use the help of the user to hang up to steal the user's property and number. Workaround:

1. Change the password immediately after discovering the verification code, and kill the Trojan 2. After you are required to verify the password, it will enter the observation period, and the system will automatically cancel it after 10 to 20 days of normal use; If the password is leaked again during this period, you will continue to be asked to enter a verification code.

Q: Why do I suddenly need to enter a login verification code when logging in to my QQ?

A: If you find that you are prompted to enter a verification code when you log in with the correct number and password, there may be several reasons:

The password has been stolen and detected by the system by someone else who uses it to send ads or scam messages without your knowledge.

2.Someone on the network (e.g., Internet café) who is using is engaging in some behaviors that endanger the security of QQ users.

3.The system has detected that the province where you are currently logged in to QQ does not match the province where you are located.

4.QQ logged in using on-hook software.

Q: Since the login verification code is a security measure, then I need to enter the login verification code, does Jian Seep mean that my QQ is no longer safe to hail? What am I going to do?

A: You need to enter the login verification code, which means that the QQ number has become insecure or there are insecurity factors in the network. If the last login prompts that the last login is not in the province where you often log in, and it does not match the actual situation of your login, it means that your QQ password has been stolen and used by bad people, and the measures you should take are:

Change your QQ password immediately and use QQ Doctor or other professional antivirus software to detect and kill the Trojan.

Q: If I take the security measures you mentioned, how can I cancel the verification code?

A: After changing the password and upgrading the password protection (the password protection scheme launched by Tencent), and after the antivirus, the QQ number that has not been illegally used for a period of time will be restored to normal mode login. However, if your computer is stolen again due to a Trojan horse and the password is changed and you engage in illegal activities, the system will continue to ask for a verification code.

So regularly update and upgrade your local computer's antivirus software, and in the.

Scan in Windows Safe Mode to avoid virus effects.

1 Your QQ number has the behavior of "abnormal login modification". For example, your QQ number has been prompted to be forced offline many times during normal use; Or someone tries to change a large number of QQ passwords, delete friends, query or transfer Q coin game currency, etc., and your number is unfortunately in it. 2 Your QQ number has been repeatedly complained about "spamming ads".

This may be because you have fallen for a virus by mistake by some malicious**; Or misuse the AFK**, the account number was stolen, etc. At this time, your QQ number is used by a small number of bad people to distribute spam ads, causing harassment to your friends and some QQ users. 3 If you use a mobile phone service not provided by Tencent, there is a risk that your password will be leaked.

Tencent currently provides mobile phone services including: SMS mobile QQ, mobile software mobile QQ, and WAP mobile QQ. If you're using a service that isn't listed above, it may not be secure, so we'll also protect your number from logging in and send you activation reminders.

There are some anomalies that you can spot on your own. For example, if you find that your number has sent strange messages to your friends, or you have been kicked offline for no reason, or your friends have been deleted for no reason, or your Q coin game currency has been consumed or transferred, then your QQ number is likely to have been obtained by the number thief. However, some anomalies can only be detected by the QQ account anomaly detection system.

Tencent has established a QQ account anomaly detection system, which is similar to the bank credit card anomaly detection system, which can quickly detect numbers with abnormal behavior, notify users and protect the security of user numbers through various means. Satisfied.
