Ask Slashdot: Securing a Windows Laptop, For the Windows Newbie?

madsdyd writes "I am a long-time user of Linux (since 1997) and have not been using Windows since 1998. All PCs at home (mine, wife's, kids') run Linux. I work professionally as a software developer with Linux, but the Windows installs at my workplace are quite limited, so my current/working knowledge of Windows is almost nil. At home we have all been happy with this arrangement, and the kids have been using their Nintendos, PS2/3's and mobile phones up until now. However, my oldest kid (12) now wants to play World of Warcraft and League of Legends with his friends. I have spent more hours than I like to admit getting this to work with Wine, with limited success — seems to always fail at the last moment. I considered an Apple machine, but they seem to be quite expensive. So, I am going to bite the bullet, and install Windows 7 on a spare Lenovo T400 laptop, which I estimate will be able to run both Windows 7 and the games in question." Read on for more about the questions this raises, for someone who wants to ensure that a game-focused machine stays secure. madsdyd continues: "Getting Windows 7 from a shop is surprisingly expensive, but I have found a place where they sell used software (legally) and can live with that one-time cost. However, I understand that I need to protect the Windows installation against viruses and malware and whatnot. The problem is, I have no clue how. One shop wants to sell me a subscription-based solution from Norton, but this cost will take a huge dip into my kid's monthly allowance — he is required to cover the costs of playing himself, so given that playing WoW is not exactly free, this is a non-trivial expense for him. On the other hand, he has plenty of time, so I guess he could use that time to learn something, and protect his system at the same time.

How do other Slashdotters provide Windows installations for their kids? What kind of protection is needed? Are there any open source/free protection systems that can be used? Should the security issues be ignored, and instead dump the Windows install to an external disk, and restore every two weeks? Is there a 'Windows for Linux users' guide somewhere? What should we do, given that we need to keep the cost low and preferably the steps simple enough for a 12-year-old kid to perform?"

      Contrary to what a 1998 level of experience with Window might infer, Windows has gotten a lot more secure. The best protection is good habits and using known safe software. To help avoid infections I would recommend using Chrome or Firefox, as there are still zero-days out there for IE. Avoid crap from Adobe if at all possible. Teach the kids not to install or run random programs from the internet (yea, I guess your safer there on Linux). Install Windows 7 with the UAC enabled and either run the kids with a non-admin account or teach them that the UAC prompt is important, same as you'd do under Linux.

The easiest path into the windows machine is by far via the user. The ASLR implementation is quite good, so even any exploits (such as browser-based ones) fire only occasionally. Apparently windows 8 has improved ASLR, so you can expect the next Win7 service pack to get the same treatment.

If you put it on its own partition you will make defragmentation a lot easier later when you have to do it.

      Stupid advice, based on an old Unix/Linux myth.

      Consider this: What is the paging file actually for? Yes, for swapping out "dirty memory" when the memory pages are needed for something else. The paging file is *not* used like a large video file. It is being accessed *randomly* (non-sequential) *most* of the time.

      What if the primary concern with fragmentation? Answer: Excessive head movements.

      And you advice users to place the paging file on another partition, all but *guaranteeing* excessive head movement on *each* access to the paging file? The original recommendation to place the swap file in its own partition was that Linux (and most Unix'es) fails pretty horribly under low-disk space conditions. I.e. the recommendation was for space management - not for controlling fragmentation.

      Fragmentation of the paging/swap file is a non issue. The OS rarely need to read more than a few blocks sequentially. Actually, one could argue that the best place for the paging file in a memory-constrained system (where swapping happens a lot) is at ½ disc width - or centered in the partition. If that happens to be interleaved with other files which are also access in a random-access pattern - so be it. It is still more optimal.

      The *only* files that really benefit from *not* being fragmented are large files that are access in sequential fashion or which account for a very large share of all disc accesses (such a large video file or a database file in a single-instance database server).

      If you are concerned that the paging file may grow and shrink and thus cause fragmentation of *other* files, then simply reserve a minimum size for the paging file. If you keep it on the same disc as the OS, then you should definitively keep it in the same partition as the rest of the OS. Now, if you could move it to another physical disc - that would offer a performance improvement - as long as you reserve that disc for paging.

      But suggesting to move the paging file into a location where you are guaranteed to *increase* head movements - that is nonsensical. Unfortunately that is a very hard myth to bust.

Sure, this is not what Stallman would say, but then he does not support PCs for a family.

    1. Windows 7 on a new laptop.

    2. Install Microsoft Security Essentials. It's free (beer). Don't bother with Norton.

    3. Create a regular user account for your son. Ensure the account is not able to modify system files without asking for the admin password. This prevents most of the nasty things malware tries to do. WIndows security is actually really good these days.

    4. Order a Blizzard authenticator to go with WoW. This excludes more nasty things that malware might do... just in case!

    5. Back up the machine after you install the games but before you hand it over to your son. Use backup software that will generate a disk image like Macrium Reflect Free Edition. Restore this disk image from a live CD (Reflect can create one for you) if your son has any problems. You have to use a full disk image for Windows because restoring an install is not just a matter of copying the files and rerunning update-grub.

    6. When working with Windows, use the same patience you have to use when working with an unfamiliar Linux distribution. Don't expect everything to be straightforward or logical, and be pleasantly surprised when it is. The only extra thing you need to beware of, but Linux users do not, is that there are scam sites which offer to "help" you with common problems, e.g. device driver issues, and serve up malware instead of help. Good practice is to research Windows problems on a Linux machine.
