This tutorial will be suitable for all popular web browsers: Google Chrome, Mozilla Firefox, Opera, Microsoft Edge and Internet Explorer.

##Viruses
First of all, your computer should be checked for malware, adware, and other unwanted programs. Too often, they prevent your browser from working properly and opening websites when you need it.

You can check the computer for viruses with one of the many popular antivirus products. They are so numerous that it is hardly a good idea to mention all of them. However, you are welcome to watch one of our videos about getting rid of viruses, Trojans and adware.

##Configure the proxy server in your browser
If you removed all viruses and unwanted software but your browser is still playing tricks with you by refusing to open any websites, it’s time to check local network settings for your computer. Here is how you do it:

Go to Control Panel – Internet Options (in Windows 7, this item has the same name).

In the tab Connections click LAN settings. If you have the checked box next to Use a proxy service for your LAN…, uncheck it and check the box next to Automatically detect settings instead.

You can also open the proxy server settings menu from the browser. For Google Chrome, Opera and Yandex Browser the steps are similar:

go to Menu / Settings / Advanced,

and click on Change proxy settings. Then follow the steps I have shown before.

In Mozilla Firefox:

go to Menu – Options – General – Network Settings – Settings.

When the menu Connection Settings opens, select Use system proxy settings.

In Microsoft Edge, go to Menu / Settings / Advanced and click on Open proxy settings.

If manual proxy setup is enabled, turn it off and then go to the tab Automatic proxy setup to activate Automatically detect settings.

##Open the registry editor for AppInit_DLLs
If the browser won’t open websites even after proxy setup operations, you should check the entry AppInit_DLLs in the registry editor. Here is how you do it:

Run Registry Editor. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\.

![Run Registry Editor](https://hetmanrecovery.com/pic/blog/a227/regedit-02.jpg)

Right-click on the entry AppInit_DLLs and click Modify.

![AppInit_DLLs and click Modify](https://hetmanrecovery.com/pic/blog/a227/regedit-03.jpg)

If in the Value line you can see the path to any .dll file (for example, C:\filename.dll), it should be deleted. Before that, copy the path to that file, clear the line and click ОK.

![it should be deleted](https://hetmanrecovery.com/pic/blog/a227/regedit-04.jpg)

hen paste this path to the file explorer, enable the option Show hidden files and delete this file as well as any other suspicious .exe files which are in the found folder.

Once again, go to the Registry Editor, find the entry AppInit_DLLs in the section HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\, and repeat the steps I have described above, then restart the computer.
