Firewall rules for Avast ping home?

Crossposted to http://forum.avast.com/index.php?topic=34656.0

I just installed Avast antivirus (home edition). According to the

online help, I should configure the firewall to allow access to

URL: http://www.asw.cz/iavs4pro

IP: 195.70.130.34

URL: http://www.avast.com/iavs4pro

IP: 64.246.6.135

URL: http://www.iavs.net/iavs4pro

IP: 207.44.156.15

URL: http://www.iavs.cz/iavs4pro

IP: 62.168.45.69

According to

http://support.avast.com/index.php?_m=know...&kbarticleid=25,

the programs that should be allowed access are

avast.setup

avastXX.setup (where "XX" are some numbers)

aswUpdSv.exe

ashServ.exe

ashWebSv.exe

However, I'm getting firewall access requests that correspond to

neither the IP addresses or applications listed above. The requests

are pings (ICMP[8]) to sl2XX.avast.com, where X varies from 09 to 14

(and probably beyond, except that I got tired of them and created a

blocking rule). The IP addresse are 75.126.203.67-72. There was also

one to sl205.avast.com (75.126.130.172). The firewall lists the

application as tcpip kernel driver.

I haven't found any information on legitimate IPs for the pings. Do I

have to open up the firewall to all outgoing pings? What is the

impact on Avast functionality or updatability if I don't?

I've brought this discussion over to the Avast forum under

http://forum.avast.com/index.php?topic=34656.0. With luck, it will be

feasible for Avast to provide a complete set of firewall rules

(fingers crossed).
