All fixed...
1. using command prompt in my 7 disc, i issued the format command. it took several hours, but once that was done. i did a clean install of 7 pro. no problems carried over.
2. put norton is back. will never trust ms security essntials since it was its failure to stop malware which originally messed up this laptop (removing the malware messed up the following in the os: command prompt, ctrl+alt+delete, corruption is user account which affects taskbar, inability to install either adobe cs2 or 7 sp1 beta)
3. adobe cs2 installed normally now
fyi: norton isn't bloated anymore and is an effective av software. norton of several (3+) years ago was bloated. norton has saved my butt on many ocassions. i have tried many types of av.
