The other day my friend changing the settings on our routers (wifi shared by multiple people in the house) and introduced a second router to enable him to get greater access to the internet. However, since this date I have had a couple of warnings over DNS cache poisoning attacks and same IP address being located on the router (I think ...sorry my IT knowledge is very limited).
I read about flushing my DNS cache which I have done but also about resetting my hosts, Ive tried to do this but when I go the system32 and drivers section and then the etc folder to rename the hosts file and create another I cannot create a new text document as I do not have that option when I right click (only new folder)
I have tried to look at online solutions but got a little lost
When I go into Regedit is shows the following
Default Reg_SZ txtfile
Content Type Reg SZ text/plain
Perceived Type Reg SZ text
under persistency handler it shows
default Reg SZ (5e94qd80-bf96-11cd-b579-08002b30bfeb)
Default Reg SZ and There is nothing under the data column
Item name Reg_Expand_SZ @=%SystemRoot%\system32\notepad.exe,-470
Null file Reg_SZ and again nothing under the data column
Can anyone help please?
