Many thanks for all your input, Techie101, Svenouk, and Jusme,

Looks like we’re getting this sorted out, without Avasts’ help. Just our luck that they are on holiday!

Jusme & Svenouk, by disabling the rpcltscm.dll, are you sure you’re not preventing some other important/useful program/process from working?

Does anybody have any in-depth knowledge on this one?

Cheers all,
