Fingers are crossed here, too. Good luck!
External optical drives are inexpensive and a good investment for netbooks that don't have them. I got one to use on my netbooks; it outlived all three of them. One of the reasons I upgraded to a notebook was to get a built in optical drive (lugging around and hooking up the separate optical drive was a PITA); others were a real num pad, a faster processor (the i3 runs circles around the Atom), more RAM (4 GB vs 1 GB...duh!), and more storage.
Another antimalware program you may want to consider is the free version of SAS (SuperAntiSpyware). As good as MSE and MBAM are (I use them myself), they don't catch everything, especially spyware like tracking cookies (no one program, free or paid, will catch everything). SAS will catch the occasional tracking cookie that slips through MSE and MBAM on my computer (I run a scan with MSE first, followed by MBAM, then SAS). It also plays well with MSE and MBAM; just don't try to run scans from more than one program at a time. I do weekly scans and almost never get any viruses, trojans, etc. I do get an occasional tracking cookie that SAS will find and zap for me. They are probably harmless but it is my computer and I'm darned particular about who puts what on it, especially when without my permission.
