on every attempt to update the Antivirus (either manually or on a schedule) I am getting this error: "Check your internet connection or change DNS or mirror server."
I do not use a proxy, the network settings are OK but still no luck.

I am also having problems with the online DSS check for updates. it always gives the error: "Update file is corrupted."

The system works just fine - no other errors. those two are really annoying me.

Please help.
