So friends, i come up with the solution or fix of the above mentioned problem.

Fix Not able to install Antivirus problem

Nowadays viruses not only infect the exe(executables) files or dll(dynamic link library) files but Hackers who code viruses became more smart and they started concatenating and modifying the configuration files of windows like ini files, host files, log files etc. Now what they do they add their own configurations to your system files which make your system vulnerable to hackers, so that they can exploit it easily. Recently hackers have started modifying the host file in windows. Host file is actually used to map any ip address with website name. Host file is also used to block any website, so that user or any application cannot access that website. For blocking any website, what hackers do is that they map localhost IP addess with any website. Hence, whenever user or any application tries to access any website, it translates website IP address to localhost address which is usually 127.0.0.1 . This technique is known as back looping. Back Looping means your web browser will search the particular website address into your localhost and when it doesn’t find it there( off course it will not find it) its shows page not found. So what hackers do, they add all the antivirus websites and their update servers to host file and bind their IP address with localhost IP(i.e. 127.0.0.1), so when your antivirus tries to update or install, it doesn’t find the antivirus server and hence update fails. So friends how to fix this issue or problem. Here are the steps to fix the “Not able to install any Antivirus” or “Not able to update antivirus” problem.

Steps to Fix Not able to Install Any Antivirus or Update Antivirus:
