Topic: Should I block this?

[Simon]

Each time I go to disconnect from the Internet, Sygate  is popping up with the box below.  I have just done Ad Aware and Spybot scans, and have Spyware Blaster, and Trojan Hunter running.  It seems that Windows Explorer is trying to tell something that I am signing off.  Should I block or allow this?

Its a bug in Norton I believe  

[Simon]

I'm not using Norton, Hook.  It's Sygate.  

Any ideas, anyone?  It still keeps asking!  

[Tony]

Well Simon, if saying no does not effect any running systems, tick the "remember answer" say no, and get on with the rest of your life mate

Have you tried running Shields Up to see if port 80 is stealthed Simon?

[Simon]

Yes, Clive, all stealthed.

crl.verisign.com seems to be some kind of certificate repository.

I would guess that something on your PC is requesting verification of a digital certificate for some reason. Seems odd for it to happen through explorer.exe though.

I would block it until you find out whether it is useful, or something breaks

[Simon]

Well, the information I found here suggests it's checking for updates to Digital Certificates, so, on balance, I've allowed it.  If I block it, there's a 5-6 second lag each time I right click something in Windows Explorer, like the poster in that thread.

I block everything i'm not sure about simon, so personally i'd go with tonys suggestion.
