How do I secure my computer system

Helpful and useful

Your data can be lost on any computer system for a variety of reasons, such as virus attack, hardware defects, software errors, user errors. You should therefore insure yourself well against this, as otherwise a lot of work and money is often lost.

We recommend that you keep your programs and data strictly separate. What does it mean exactly? A program is, for example, Windows (the operating system) or Word (a program for writing texts). These programs are or have been set up by you once on your computer, usually after purchasing the computer or the program. From this point on you have worked with the programs: For example, you have written invitations in Word or created your annual tax return with Excel. And you have saved this data in separate files somewhere on your hard drive.
Hopefully you can already see the subtle difference between programs and data here. Not all files are the same.

It is advisable to set up a central folder on the hard drive for your data, or even to partition your hard drive into two parts or to install a second hard drive. No matter where, ultimately this is where you should put all of the files you have created. New Windows systems even offer a standardized "My Documents" folder for this purpose. This should be taken with a little caution, since the use of this standard directory is again susceptible to infection by special computer viruses. So it's better to create your own directory or use your own hard drive.

Of course, this is only the first step, because it will hopefully never be of any use to you in an emergency. Back up all data in your central storage location regularly (preferably daily) to an external medium. We recommend external USB hard drives for this, but CD or DVD burners, tape drives, network drives or the like can also be helpful. Since your data is stored centrally, it is not difficult to copy it accordingly.

Integrated programs, i.e. programs in which you as a layperson do not necessarily have the opportunity to influence where your data is saved, usually always offer the option of saving or exporting the data. Experience has shown that this is particularly important with e-mail programs such as Microsoft Outlook or Thunderbird. Do this regularly and include the data in your backup by simply storing the exported file in your central folder.
This protects you against major data loss in the event of problems and, in the worst case, you can restore your data from the backup.
