There are several issues with the pre-installed application, one is that it is an ad-injector which inserts adverts into your browser based on what you are searching for, and without being an expert at identifying these you might be directed to sites to purchase things without understanding why.
To do this more effectively, Superfish also installs a root certificate which allows them to see traffic on encrypted websites, like your banking website, that you might have considered private and secure.
This is a bit like me giving out the keys to your house and could be abused by other malicious people and used to capture passwords and other personal information.
AVG detects and removes the Superfish add-on. If you have attempted to download something it was bundled with then AVG would have detected and blocked it advising the user it was an ‘unwanted application’ and potentially harmful.
This means no part of it was ever installed - good for existing AVG users, but what about if you have purchased a Lenovo and then installed an antivirus product, the risk here is that full removal of some parts are difficult to remove as they are embedded into the system.
This week Lenovo has been re-active to this and developed a removal tool which you can download here. There are also manual instructions available should you want to do this yourself.
There is a much wider issue for consumers though, it’s becoming very difficult to know which products and manufacturers to trust and who is doing what with our data.
There are discussions in the tech industry on improving transparency so that consumers can once again have confidence in brands.
I believe that over the next few months we will see progress in a more coordinated effort by the security industry to protect users from these types of applications.
If you are at all concerned then be sure to run a full system scan from your antivirus product and ensure that the updates have been run. If you’re running an expired product then either renew it or download the AVG AntiVirus Free solution here.
