Information Connection: Computer viruses

Virus. The word sends many of us into spasms of panic--we quickly e-mail everyone we know, warning them not to open an e-mail that says "Good times" or some such in the message.

A virus, by definition, is a program that replicates. And when you send e-mails out about a virus, you are then part of the virus, because you are helping to replicate a message that is already consuming Internet resources. Your intentions are good, of course, and this is what pranksters count on. So, beat them at their own game and don't forward those virus e-mails!

Purists will say a virus is a program that replicates itself, but a program that does not replicate itself is not a virus, even if it does something nasty. Most of us refer to any nasty program (e.g., Windows 95, Windows Me, Windows 98) as a virus. So, with that in mind, here are some protective measures you can take:

  1. Many experts advise to install and run a good virus protection program. This was good advice at one time. But these programs have morphed into intrusive, resource-draining crapware that fits the definition of a virus itself.
     
  2. Use freeware and shareware--especially games--with extreme caution. Many viruses and Trojans come bundled inside such programs. If you download such a program from someone's website, it's probably safe. If you get it attached as an e-mail or on a floppy that is making the rounds at the office, watch out.
     
  3. Set your CMOS so your computer does not seek a floppy (or other removable media) at boot-up. This prevents you from getting the nastiest of the viruses/Trojans out there, because these have to load at boot time. Similarly, don't open e-mails with attachments you didn't ask for--these can load executables on your root drive and do similar damage.
     
  4. Don't use pirated software. If someone will sell you pirated software, do you think that person has any qualms about  passing along a virus?
     
  5. Set up your word processor to ask you before enabling macros. If you always select "no," you become immune to macro viruses--you can always enable the macro after doing a virus scan.
     
  6. Visual Basic scripting was really cool when it came out. Now, the virus writers use it for their nefarious purposes. You need to disable script execution in your browser settings or risk getting a VB virus. Sigh.
     
  7. Faithfully do your Windows updates. Even though Steve Ballmer is the CEO of Microsoft, the company does get some things right. The Windows update program is one of those things.
     
  8. Work behind a good router. You can define "good" as one that includes a firewall. With this kind of router, a hacker can see the IP address and MAC address only of the router. Your computer (and anything else on the network) is invisible to the hacker.
     
  9. If using a wireless router (and most people do that, these days), use the strongest encryption and security it offers. This can be a tad inconvenient, but if you pay attention to what you're doing during setup you can minimize later inconvenience.

 

Computer Resource Quicklinks

Working the Windows Desktop

The whole desktop approach ignores the fact that a computer's hard drive(s) are the electronic version of a paper filing cabinet. It also ignores the fact that people store a huge amount of files in that system. And it ignores a few dozen other facts relevant to using a computer. It's just a bad approach.

The desktop assumes you don't care what files you actually work on. It opens apps, not files, and this is the pathway to problems. You can inadvertently be revising the wrong thing, if you can even find it in the first place.

What you should do instead is use Windows Explorer. Microsoft tends to hide this, but it should be your standard interface with your computer, unless you don't mind working blind.

You can always right mouse click the Start button to invoke it, but you should add Windows Explorer to your Quick Launch bar and several other menus in Windows.

The default settings for Windows Explorer defy logic. Change these so you can actually see what files you are looking at. Enable it to show you the file extensions (unclick the insane "Hide extensions" box that is, stupidly enough, checked by default though actually there is never any reason to ever check this box). Select the option to show details. Now, you will be able to see your file size, file date, and other useful information. If you right click around a bit, you can find quite a bit of functionality in Windows Explorer.

If you haven't been using this interface previously, make a point of using it now. If you always open files from within Windows Explorer, you will always be able to see all available files and select the right one.

Use Windows Explorer to set up your filing system as if it's a paper filing cabinet. Save all files either on the data drive (dual hard drive machine) or in a folder on a single hard drive machine. Do NOT save files to the default locations. These never make any sense. They are typically within your applications, which is a dumb place to save them. That's how you end up with corrupted data files and it also makes file backups difficult.

For single-drive users, an easy solution is to create a folder called 0files as your top-level data folder. The zero means it will show up at the top of your file list, making things easy for you. Below this folder, create you filing structure. Never store anything at the root of this folder. Think of it as the shell of a five-drawer filing cabinet and don't toss stuff in the bottom. Always put files in folders that are in drawers.

With a good filing structure in place, you will always be able to find your files by simply clicking right to them. So think this out as you go and follow a good taxonomy. It's a much more effective way to work than how the zombies at Microsoft envision people working.

 

Recovering hard drive space

Even with today's huge drives, people sometimes run out of hard drive space. The steps below can recover wasted space.

  • Do a search for *.tmp files. Delete all of them. Then defrag your drive.
  • Do a search for *.bak files. Delete all of them. Then defrag your drive.
  • If you have any *.bmp files, change the format to *.jpg. This will result in radically smaller files. You need an image tool for this; if you don't have one installed already, then skip this step.
  • Set the Properties for the drive to compress files. In Windows Explorer, right mouse click the drive name. Then select Properties. Then select Compress to Save Drive Space. This could take a while, so unless you want your machine tied up for a few hours do this process one folder at a time and then do it for the whole drive.
  • If this issue is for your programs drive, then remove any programs you aren't using. Go to Control Panel | Remove Programs.
  • On your data drive, zip files you aren't using.

There are other steps you can take, but if, at this point, you are still low on disk space you really need to add another hard drive or upgrade one that's in your system. Or, another very cool option, is to add a My Ditto system. See our Review of the Dane my Ditto network server.
