As is well known that such open proxies are not desirable as they can be a source of any Computer offence/crime and may have economic implications. Also such type of security breach attracts penalties under IT Act,2000.
You are requested to kindly take immediate steps to stop these hosts functioning as open proxy. We greatly appreciate your prompt attention to this matter. Please intimate us about action taken in this matter at the earliest.
If you are not the appropriate staff to handle this matter, you are requested to immediately escalate this matter to the attention of concerned authority.
The above information I got from the - Indian Computer Emergency Response Team (CERT-In),Department of Information Technology

In this place I am running my network with Mikro Tik router So how can i stop this?
You can start by blocking incoming connections to your network on tcp ports 80, 1080, 3128 and 8080. It’s only. a temporary solution. A more resource exhaustive solution would be to set up a layer7 filter but you have to know what data is being exchanged when somebody initialises a connection to one of your network computers hosting an open proxy
Firstly you should block all traffic to the router from the WAN interface(s) (drop all rule(s) in input filters) then permit the specific traffic that should be allowed to access the router (specific accept rule(s) in input filters).
