Option 1 (new x).

Note (Original):

1 In safe mode, the effect is even better!

2.All the software to be used below should be installed or upgraded to the latest version to ensure the effectiveness of use.

3.It is not antivirus, and the following methods can be used directly. If the effect is not good, first kill it with a high-quality antivirus software (such as Kaspersky) in safe mode, and it is best to use 360 Security Guard as well, and then use the following methods.

Use 360 Security Guard's "Trojan Horse" - Full Scan". Kill and restart. ）

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

One. Close the browser, open the "System Repair" of the new version of 360 Security Guard, scan it, and then click "One-click Repair".

Then use the 360 first aid kit (360 Security Guard's "Function Encyclopedia" is available.) If the 360 security guard is not installed, a separate first aid kit can be installed. Follow the steps:

"Start First Aid" first; After scanning, restart; Then click "System Repair" (you can select all of them to Repair Now". Next, click on "DLL File Recovery", add the missing DLL file that the system detected during detection, and then click "Repair Now". Repair Network is a case-by-case decision to fix or not.

When you're done, you should restart. 】

Two. Scan with 360 Security Guard's "Clean Plugins" to clean up malicious plugins. When you're done, you should restart.

Three. Use Windows Cleanup Assistant (from the web**). After scanning (if you sweep things out, check them all and clean them), then use Fault Repair (select all), and then right-click on the desktop to refresh. Works well in safe mode.

You can also consider using the Kingsoft First Aid Kit [Tick the "Extended Scan", after point scanning, if there are items that can be repaired, after selecting all, click "Deal with it immediately", and restart it after finishing. 】

You can also go down to an IE restoration expert, or a Yahoo ie restoration expert (there are also people who use Huangshan restoration experts). When you're done with it, try again: click on the top of the page Tools - > Internet Options - > change the homepage to what you want.

2.After installation, click on the one-click repair. After sweeping out the thing, the dot is processed immediately.

Emphasis ---1In the repair, when there is a prompt in Kill Soft or 360, please click Allow. Restart the computer if prompted to restart during operation.

2.When the effect is not good, look at the three points in "Attention". 3.

After that, if the effect is not good, you can also consider system restoration (choose a restore point).

If that doesn't work, upgrade or reinstall your browser.
