Sorry for taking so long to get back on this.
I was waiting for my Co. IT guy to give me a copy of Ad-Ware Pro. I figured I should run something more then a basic copy.
I did a "Smart system scan" ~ nothing came up.
Then I did a "Full system scan" ~ 32 Negligible objects came up.
Scan summary list them as "MRU List" which poses no threat.
Deleted all cookies again, deleted Mrexcell.com as home page, History is empty, shut down PC, restarted, log on to mrexcell.com manually ~ still have the same problem.
Nate, I did not follow through with Jon's latest suggestion yet, because I did not want to insult you since you have spent some time on this and maybe was just waiting to see the outcome of runnining Ad-Ware.
I am open for suggestions.
Thanks for both of you folks time on this.
