Ok, your log is clean... this is part of what I wrote for someone else concerned by the same rb files appearing [rb for recycle bin..]:
Some of the smaller Antivirus service providers use common software "engines", rebadging commercial software, if you like. An antispyware example is your CA [computer associates] service, which is eTrust PestPatrol.
Internet service providers like to provide an in-house AV service, mostly they are rebadged commercial versions. One they provide is Command AV, which is the same as Authentium AV.
Authentium\AntiVirus\dvpapi.exe is also part of Freedom AV, amongst others. They will pop rbn.tmp files in your Recycle Bin [n is a digit]... is that where your rb.tmp files appear?
PCGuard will do it, also. Lots of ISPs offer that.
If those files pop in your RB as I surmise, then ignore them.
I think I have all that straight up.
Deep, deep in the woods, but walking about.
