Can someone explain to me why you deduce bad system security from DCOM-Exploit warnings (which I assume are coming from avast network Shield) ?
You ALWAYS get those as soon as you connect to a contaminated network (i.e. the INTERNET), even if you have all WinUpdates in place
and if avast driver is loaded before firewall driver, you even get those warnings with a FW installed
(ok, "Smartcard" hasn't got SP2, which should be applied, but this doesn't necessarily imply that his system is vulnerable to DCOM/LSASS/etc.- Exploits)
@Smartcard:
please post here a hijackthis-Log for diagnosis;
