Make a cmd really fullscreen

Many of you, who use windows computers, now this problem:

You start the cmd-tool and want to make the cmd fullscreen. But the only way to make it “wannabe” – fullscreen, is by editing the properties.

But wouldn’t it be awesome, if there would be a way to make the cmd really fullscreen? Yes it would be. And yes, there is a way. The solution is regedit. Follow these easy steps, to make the cmd able to go fullscreen and,  you will never have to deal with this problem again.

1. Launch the CMD and write the following code:

mode 800

2. Now you can make it fullscreen by pull the menubar to the top of the screen or resize it, to whatever size you want.

If you want, that this is set by default, do the following:

  1. Open an editor and write in the code
    @Echo Off
    mode 800
  2. Now change the filename to  .cmd or .bat
  3.  Put it in the autostart.
    To put it in the autostart for all users, do the following:
  4. Go to the registry by entering regedit.exe in the windows-searchfield.
  5. Go to the following path:
    HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor
  6. Optional: If you want to do it just for the actual user, go to the following path:
    HKEY_CURRENT_USER\Software\Microsoft\Command Processor

3. Now add a key from type REG-SZ with the name `Autorun` and put the path of the script in the data-section of the key.

4. Now you have to change the value of the value. Rightclick on the key and choose `edit`.

5. Now set the value to the path, where your script is:

Everytime you now launch your machine, your cmd will be able to go fullscreen.

Antivirus on Mac OS X – Useful for you and others

The question, if it’s important for Mac OS X users to use antivirus-software, was often discussed.

There are many pros and contras from the different parties. But let’s take a closer look.

The Arguments

Users who don’t use such a piece of software, use arguments like this:

  • There aren’t any viruses for OS X
  • Mac OS X applications are safe without an antivirus

Users who do use such a piece of software, use arguments like this:

  • My mac is now completely safe, because I’ve got the normal safety of the OS X and also the antivirus-software

Arguments investigated

Let’s take a look at these arguments, if they are valid, or invalid.

There aren’t any viruses for OS X

This argument is invalid. There were many known viruses, trojans, and worms. A simple google serach shows the different case. securemac.com for example shows an actual list of keyloggers, malware, trojans etc. Of course there are many more pieces of bad software out there, which aren’t listed.

But of course the motivation to write software for an operating system which has only a market share of less than 10% is much lower then to write software for windows. So there aren’t no viruses, but much less.

Mac OS X and its applications are safe without an antivirus

This thesis is simply false. Yes, there currently aren’t any known viruses which target OS X, applications have issues. And if you use third-party applications, the danger is even higher. And if someone has the knowledge to use these issues then you will regret your renunciation.

Antivirus software often also includes other features which provides safety before danger from infected web-applications or websites which includes viruses, trojans etc.

My mac is now completely safe, because I’ve got the normal safety of the OS X and also the anivirus-software

A computer which runs any software, is never completely safe, because as seen before, also with an installed antivirus-software, there are viruses which this security-softwares won’t know.

spreading – An often forgotten danger

There is one more very important thing that is often forgotten: spreading

Let’s take a look at the following scenario of an email conversation.

  • The virus-attachment of the email contains a funny picture and the virus.

The scenario without any antivirus software

  1. Albert receives the email with the virus. He opens the attachment and the picture in it. The virus invisibly starts his work and corrupt files and sends himself to all users in the addressbook.
  2. User Bill who is in the addressbook of Albert receives the email. He opens the attachment. Because he uses a Mac the auto-resend function from the virus doesn’t work. But also the virus stays undetected. Also because of the funny picture, Bill sends the email to some of his friends, including Anna.
  3. Anna now opens the email-attachment and because she uses a windows computer, the virus can now do his work again and spread.

The scenario with an installed antivirus-software on the involved Mac

  1. Albert receives the email with the virus. He opens the attachment and the picture in it. The virus invisibly starts his work and corrupt files and sends himself to all users in the addressbook.
  2. User Bill who is in the addressbook of Albert receives the email. He opens the attachment. Now because of the installed antivirus-software, he receives a warning because of the content of the attachment. The antivirus deletes the attachment and the danger is gone.
  3. Because Bill now know about the virus, he can inform Albert and the spreading stopped.

Conclusion

Of course you can run your Mac without an antivirus-software. But to protect you, and your co-workers, friends etc. it would be much safer to use such a piece of software.

As I’m writting this blog-post I’m on a MacBook running the McAfee-antivirus for mac. But there are many free solutions like avast which do their job. It doesn’t need as much time to install such a software as it takes to reinstall your whole system or recover your logins after a virus has attacked your system.
