Cause analysis:

Mainly some malicious software and ×××, through third-party browser extensions, modified dynamic link library registration.

Solution:

Method 1:(This method is a bit complicated, if different browsers, to change the specific name, the following IExplore as an example)

1. Click Start, Run, enter iexplore.exe and click OK.

2. In IE, click Internet Options on the Tools menu.

3. On the General page, click the Use Blank Page button.

4. Click the Delete COOKIE button and click OK

5. Click the Delete All Files button and select the Delete All Offline Content check box, then click OK.

6. Click Settings and select View Objects

7. In the Downloaded Program Files window, click Select All from the Edit menu.

Delete all selected ActiveX files

9. Click the Clear History button and select Yes.

10. Set "Internet, Local Intranet, Trusted Site, Restricted Site" in "Security" page to "Default Level" respectively.

11. Set the level on the Privacy page to Default

12. On the Contents page, click Clear SSL Status and select Yes

13. On the "Advanced" page, click the "Restore Default Settings" button and clear the "Enable third-party browser extensions (restart required)" check box, then click "OK" and exit IE browser.

Method 2:"For" command method (after actual operation, relatively thorough, do not restart)

Analysis: Most of the dynamic link libraries in the system are stored in the System32 directory. Use the "For" command in the Windows command line to realize the loop operation, and quickly register the dynamic link libraries in the System32 directory, thus avoiding manual input commands.

1. Click "Start/Run" to

2. Enter "CMD" in the pop-up operation dialog box, enter and open the command prompt window.

3. Enter "For %i in (C:\windows\system32\*.dll) Do regsvr32.exe /s %i" at the command prompt (the actual input does not include the outermost double quotes, it is recommended to use the copy and paste command, so that it is not easy to make errors). After entering, you will start to register all dynamic link libraries under the System32 directory one by one.

Method 3: IE parameter method (if IE is used, the principle is the same as method 2)

Analysis:

There is a parameter "/rereg" hidden in IE, which can be used to register all options of IE in the registry and options related to dynamic link library one by one.

1. Click "Start/Run."

2. Enter "%ProgramFiles%\Internet Explorer\iexplore.exe" /rereg "in the pop-up Run dialog box.

Restart the computer to re-register all IE components, thus fixing common IE failures.

The above methods, if the virus is not completely eliminated after the virus, it is very likely that similar problems will occur twice. Although the above methods can be solved, if the virus is not eliminated, the secondary infection is most thoroughly based on the elimination of the virus.
