Slow, sometimes no Connectivity to the internet

I am having connectivity issues that started about 3 days ago.
My problem is slow or no loading Empty pages, timing out. Inability to post in forums-sporadic-if I get to post here from my computer, Haloscan and mozilla forums.
I have tried everything-First the reboot trick, unplugging the modem, then system restore, calling the cable people, turning off my security.
Last night I went to GRC and did the leak test, and for the first time it said my Firewall had been penatrable. Also my Messenger was on, which is something I turned off ages ago. I turned it off again.
My browser is Firefox 2.0.0.1 I have Free AVG 7.5, Free Kerio Firewall, Spybot, AdAware, Spyware Blaster. I ran scans with AVG and Adaware, all updated, in regular and safe mode. Also did a Spybot scan in regular and safe mode, but when I had tried to update it (to 1.4), there was an error message (! With red cicle slashed over it-no details), so I couldn’t do that.
I have Winduhs XP Pro, SP1. I have over half the memory free. I have not installed or removed any new programs in the period before this started up.
My email seems to come through fine (Thunderbird). My cable provider says my signal is very strong, that the ping is 4-9 ms going each way.
And FF which usually runs around 21-25,000 has been spiking to 50-51,000. As usual, IE is sucking up a storm too , so I’ve been thinking it’s not the browser. Also, I seem not to be running as many processes as I usually do.

So here’s my log. Does it look funky?
