Hi Prashant-Gupta,
I don't know whether I can help with the PC.
I don't have the tools or knowledge to disinfect mobile devices or Mac computers.
(ESET makes a mobile version of its antivirus for android devices)
I may be able to help if this problem is related to the router.
When you "Reset" the router, did you change the default administrator password for the router ?
What make and model number router is it?
askey127
