We recently took over a companies IT, and they previously used a proxy.
Looking through the server, it appeared to be using Symantec for this which have now removed.
Recently we connected one of our laptops in to their network and straight away it wanted credentials for the proxy, for us to be able to access the Internet. We entered the domain admin details and it connected no problem.
Today, I have found some registry keys which look as though they have been added / ammended on the server. (See screenshot attached). Can I remove these, or is there any where else I need to check first? I have the ProxyEnable key on my machine but the other two look to have been added by the previous IT company.
