What are you doing about PARASITES that Norton doesn't deal with or detect since "it's not a virus."
Light intro at http://www.doxdesk.com/parasite/
Multiple problems all of the sudden:
*Simple calculations use 100% CPU.
*Formulas only work if you double click the cell.
*Formulas dragged down a page using fill handle only return the value of the first cell.
*Memory leak as recent data changes have disappeared.
I ran Norton 8.0 and Avast--no viruses detected. Please help!
