I keep getting a message that my recovery disc is full. Checking it I find it has a lot of folders including the Program and Program 86 files, along with Dell, Perf Logs, Common files, etc. Is this normal or because I had to use the recovery disc to straighten out my NEW Dell 570 (Windows 7, 64 bit) because it got corrupted by a faulty Ad Aware program and wouldn't let me delete it, download Norton 360 or anything else. I'm very much a novice, very confused and CONFOUNDED! Help!
