In case you are using CIS V579 and you are stuck at certain AV definitions as AV updater refuses to update further, only resolution at this moment is to replace with latest complete base as explained under following post:
I am currently using version 3.5.54375.427
Virus signature database 994.
I have not been on my computer for a week and when I started it up, it told me that Windows Firewall was reporting the COMODO I.S. virus signature is not up to date. I went to run the update yesterday 1/8/2009 and today and it keeps on telling me that the connection failed before it downloads anything. I have a dial access modem 56k and I am able to do other activities on the Internet before and after I get the message. I have restarted the computer several times, but to no avail.
I saw this past week that the update was stopped and restarted and people were able to update, but then I see other people have had problems beginning yesterday.
Windows Vista Home Premium SP2 Dell
Intel Core 2 Quad CPU Q6600 @2.4 GHz, 3 GB Ram, 32-Bit Operating system.
I’ve had to uninstall CAV until some modest progress is made in a stable release. I think this month alone I have had to update CIS twice, required to download an entire new CAV definition and now I have had problems as described in this thread. I do hope things get better as its a pain at the moment.
Still though, thanks for a great product. Still using Defense + with the firewall.
