You both are welcome. Glad to help. 
Since this version of the SZ browser is behind the curve (obsolete) and is in place in a security environment, I suggest routinely accessing the History section of GC at the end of every session and manually deleting all visited sites using the "End of time" parameter. This should have the effect of keeping the browser cleaner as well as safer to use in the long run.
It's avast's responsibility to update their SZ GC browser, I think, as this is not the general publicly released version generally used outside of SZ.
@ MainilanLaukaus,

Appears to be an issue originating with the zombie avast! sandbox folder. Who knew?
