message in router log

[alan]

I have a Zyxel 660HW router. Can any one explain what the following log item means please?
It repeated itself about 128 times within a couple of minutes.

If you haven't changed anything on the PC(s), run Malwarebytes or SuperAntiSpyware. It maybe a program that is trying to access the router beyond the default number of open NAT connections allowed.

Thanks Glenn... Not changed anything.. I'll have to see what I can find on the net. I've got a mac.. I thought these things didn't exist on these machines.

The information is here there's a few google hits, whether you can increase via the menu or have to go via CLI not sure. Its a router issue,

There is this http://www.broadbandreports.com/forum/remark,9235388

My target is set at 512 sessions which is more than adequate according to some of those sights... Me going to get some searching for mac
spyware/malware just in case. I wasnt even on the comp at the time, although the machine was on.
.
Thanks again Glenn and Steve.

[Steve]

Alan is that 512 across all 4 ports i.e 128 per port

Sorry Steve been out all afternoon...
Telneting the router it says.. NAT session number per host : 512.
I havent got a clue about the port business.
When I was googling it says 512 was adequate.

[Steve]

I think port and host are possibly the same
