Network security

[#1]

Each time I boot up my PC without fail I get a Kapersky AV pop-up warning that my network security is weak.
In my routers set up I am advised I am on the high rate of security WPA2-PSK. The Kapersky pop-up suggests the security can be improved by uprating to...WPA2-PSK
Checking around some local networks that list in my connection pop-up, most are on WPA2-PSK except one on just PSK and two BT wi-fi's that are unsecured
So it seems to me in spite of Kapersky's dire warning there is not much I can do, unless members here know better?

Unless you are using wep or wps (check that) it is the strongest you can have without a separate server.
Wps could be the issue, it is the "press this button to connect the network" you get on some devices.

This laptop has a key (F12) that can toggle internet, but otherwise nothing else to toggle the network.

adding them to the blocked list may sort it http://www.eightforums.com/tutorials/45598-wireless-networks-allow-block-filter-windows.html

That's interesting OJ, I will take a long look at that.
Are you though advising that my AV may not be telling me my network is low security, but one or more of those in my local list?

That is what I suspect - of course I may be wrong

There's a certain elegance about your idea OJ, unfortunately, the AV pop-up names my network as having weak security in spite by other replies here I can't improve it.
The list of local networks varies in content considerably during the day, but the two unsecured BT wi-fi's seem pretty well permanent fixtures in the list.
In spite of what the pop-up says I'm inclined to lean towards your theory.
Just to have a good look at the pop-up I've just done a boot, the pop-up only stays on screen for a couple of seconds, and in very small print at the bottom there is an option "don't show this again" I very tempted to use it next time I boot the computer.
