Nothing of concern in the earlier SAS log, tracking cookies no real issue and the second as you said it clear.
I would say that the other file is unrelated (other than it is from akamai), if a problem it should also have been picked up by avast, but the single hit on the VT results, suspicious, usually implies some sort of heuristic/generic detection rather than a specific signature. Add to that the detection is from eSafe I would say that there is nothing to be worried about with this file.
If you do get a replacement rswin_3586.dll file then avast will most likely alert again (possibly by the Web Shield before it gets on your system) by the Standard Shield, send it to the chest first and then do the drill to upload to VT and report.
