Tips for Making a Safe Computer Without Antivirus – Often we panic and worry that the computer can get a virus while we don’t use an antivirus. Here are some tips to make your computer immune to viruses:
1. Use a limited account
Most Windows operating system users like the administrator account because with that account he is free to do anything to the system. But it must be realized, if he can do anything to the system, when a virus enters, the virus can do anything to the system. So, you should get used to using a limited account (non-administrator account) when operating a computer.
In the Linux operating system environment, this has become a habit. It is relatively rare, if not almost non-existent, of everyday Linux users to use a root account. This is also one of the reasons why Linux is rarely infected with viruses.
2. Turn off or set the Autorun/AutoPlay feature
One thing that seems difficult for computer users to avoid is sharing data through portable storage media, such as USB flash disks or maybe there are still those who use CD/DVD chips.
Recent versions of Windows will generally offer what to do with the portable storage media when it is inserted into the computer. Make sure you don’t execute unknown files on the portable storage media, just copy or open the files you need.
Some versions of Windows still automatically execute certain files (autorun) that are on portable storage media. We recommend that this feature is turned off or at least set so that it does not automatically run certain files.

3. Disable the macro feature in Microsoft Office
One of the virus variants that may infect computers comes through the macro feature in Microsoft Office applications.
If Microsoft Office is an application that you use very often, you should disable this macro feature, unless – of course – if you really need macros in processing Microsoft Office documents. In this case, make sure to get the macro documents from a really trusted source.
4. Show file extensions in Windows Explorer
By default, file names in Windows Explorer (now named File Explorer) are not fully displayed because file extensions are hidden. In fact, the file extension is very important to know the type of file. For example, files that have the extension .exe and .com are executable files.
Why is this necessary? Because there are certain types of viruses that are present by disguising file icons. For example, the virus is present in the form of an executable file but has an icon similar to a Microsoft Word file (.docx) or Acrobat PDF (.pdf). If the file is double-clicked, instead of opening the document, the virus will spread.
If the file extension is displayed, the user will be more wary of opening the file because the .exe extension clearly looks different from the .docx extension.
