1. Has anyone any experience comments on the newish Microsoft Security Essentials? It's getting good reviews. I have been using AVG for years, but the new version (2011) caused some serious froze-the-whole-system problems so I finally got it uninstalled and am back to AVG 9. Please don't suggest Norton: I believe it's a resource hog and I won't use it.

2. Does anyone know if it's possible to run both OFFICE 2003 and 2010 at the same time? We haven't upgraded yet. Well, we did but the function of 2003 in Excel is such that it changed how all our engineering charts display and it was a disaster, so we had to change back**. (many engineering companies had this problem) We've been using a document converter for the .docx files, but it's getting to the point where other than the excel issue, we should really upgrade. But, we'd like to be able to keep Excel as 2003.


**note on the excel upgrade. All the colors and tools for making charts were changed so that all the graphs and what not ( years and years worth) displayed different and/or inaccurately from the original input. The previous options were eliminated. MS told us Excel had been "improved" and there was no way to get the old tools back. We would have had to manualy re-do thousands of files to fix them to appear correctly, so we just reverted to 2003 and have stayed there.

ideas anyone?
