I have Windows Vista with Acer software, and I let Norton Utilities do whatever it seemed to think was necessary. I wish I hadn't, because it really messed up my display patterns. The toolbar colors are grey, so are the boxes that open when working with something like properties, for example, and the enlarge/close boxes in the upper right hand corner are so small I can hardly see them. And I don't know what it did to my display fonts I get when working online. They look thinner, much thinner and hard to read. I just installed a new printer this morning, so I hesitate to do a restore. I am also getting pop-up boxes that have something to do with Norton, probably Utilities wanting something, and I really don't like that. Is there any way I can undo whatever it did? What if I uninstall Utilities, will whatever it did still be there and impossible to change? Thanks!
