My sister t hinks someone might be using her internet connection as it has become very slow and she is having problems with it. I suspect she has never done any defrags or done any other kind of clean-up on her computer (she is not computer savvy!). But in case someone is using her connection, is there any way to stop this? Thanks.
Only way they can use her internet is, if she is using her connection Wireless, without the Router Encryption being setup in Wireless Router. If the Encryption is not setup, the connection is classed as Insecure
PS if she as her PC connected to the Router with a Ethernet cable, there is no need for the above and no one can use her connection. Unless Wireless as been enabled in the router without it being Secured
She doesn't seem to have a router - daughter's laptop now defunct! I have pointed her in the direction of Avast or AVG and also Glarys Utilities. Now sending her details of how to use them. Thanks all.
