Google redirect virus is a virus that’s designed to manipulate Google search results. It gets installed through a trojan horse. Whenever you use the Google search engine it hides the Google results and shows you advertisements or affiliate links related to that subject. Sometimes, it also shows you fake advertisements, popups, etc.
It shows you fake errors such as:
Internet explorer cannot open web page
filename.exe is not a valid win32 application
Setup files are corrupted; please obtain new copy of program
It is also capable of disabling firewalls and other security softwares which can then lead to a remotely accessible system. Hackers take this as an advantage and gain access to personal information such as login names, passwords, financial records etc.
There are several tools to remove this virus. But, I recommend ComboFix and Hitman Pro. ComboFix is a DOS based tool, hence you need to be little careful while using it and also make sure that you don’t run any other software while running this tool.
