What version of Ad-aware are you using?
Does it always do this, or is this the first time?
Are you behind a proxyserver?
QUOTE
I am behind a proxyserver and keep receiving error messages when I attempt to update my definition file in Ad-Aware SE. What is your adress to the update server, so that we can allow this in our proxy?
We use two different servers depending on the version of Ad-Aware being run:
Ad-Aware SE Personal (freeware): "updates.ls-servers.com"
Ad-Aware SE Plus/Pro: "download.lavasoft.de.edgesuite.net"
