2. In order to ensure the use effect, the following software to be used should be installed or upgraded to the latest version.

3. If there is no antivirus, you can directly use the following methods. If the effect is not good, use high-quality anti-virus software (such as Kaspersky) to kill in safe mode, and 360 security guards are the best.

(Use the "Trojan horse to kill the chicken" of 360 security guards-"full scan". Restart after killing. )

You don't have to use all the following methods, you can try them one by one. Sometimes, only the first one works.

1. Close the browser and open the new version of "System Repair" of 360 Security Guard. You can check the options of "on-site maintenance", "system maintenance" and "IE maintenance" according to the situation (you can also select them all. At least select "System Repair"), and then click "One-click Repair". Too lazy to pretend, just use the 360 first aid kit.

Use the 360 first aid kit again. Follow the steps: first "start first aid"; After scanning, if a Trojan horse appears, click "Isolate"; Click "Repair" again (you can select all)-"Repair Now". Next, click "Recover the lost DLL file", add the lost DLL file known during system detection, and then click "Repair immediately". The "repair network" decides whether to repair or not according to the situation. It should be restarted afterwards.

2. Scan with the "Clean Plug-in" of 360 security guards, and clean up after removing malicious plug-ins. It should be restarted afterwards.

3. Use the windows Cleaning Assistant (downloaded from the Internet). After scanning (if anything is swept out, check and clean it up), then use fault repair (select all), and then click the right mouse button on the desktop to refresh. It works well in safe mode.

You can also consider scanning with Jinshan first aid kit. If there are items that can be repaired, select all items and click Repair.

Focus-1. When prompted, please click "Allow" when repairing, killing software or 360. If you are prompted to restart during the operation, please restart the computer. 2. When the effect is not good, look at three points in Attention. 3. After that, if the effect is not good, you can also consider restoring the system (choose the restore point).
