Internet Security Tips | Antivirus Software

When you leave the house, you probably take precautions to protect yourself from burglaries and other dangers. On the Internet, it is also important to put in place some security procedures: fraud, espionage, and theft of files or passwords are just some of the problems that people can face in this environment.

Antivirus Software

It is to help you deal with the online dangers that InfoWester presents below some very important safety tips. All are simple, so you will have no trouble putting them into practice in your daily life.

1. Exit by Clicking on "Logout", "Exit" or Equivalent

When accessing your email, your online store account, your Facebook profile, your internet banking, or any other service that requires a username and password, click on the name/link button Logout, Logoff, Exit, Disconnect, or equivalent to leave the site. It may seem obvious, but many people do this by simply closing the browser window or accessing another address from there.

Doing so is not recommended because the site was not instructed to close your access at that time so that someone else can reopen the same page right away and access your information. This tip is valid mainly on public computers - from college, for example.

2. Create Passwords That Are Difficult to Discover

Do not use passwords that are easy to discover, such as family name, birthday, license plate, etc. Prefer strings that mix letters, numbers, and even special symbols.

Also, do not use a combination that is less than six characters as a password. It is also important not to keep your passwords in text files. If you need to write down a password on paper (in extreme cases), destroy it as soon as you memorize the sequence. Avoid using the same password on multiple services.

It is also recommended to change your password from time to time or when you suspect any strange activity, such as an email that appears as read, but that you do not remember reading.

3. Update Your Antivirus and Your Operating System

You certainly know that it is important to install security software on your computer, such as an antivirus. But, in addition to installing it, it is necessary to make sure that the program is constantly updated, otherwise, the antivirus will not "know" about the existence of new malware. All current antiviruses have automatic updates set by default, but it's always a good idea to check.

It is also very important to install updates for your operating system, including on your mobile devices (tablets and smartphones). So that you don't have to worry about it constantly, make sure your operating system has automatic update functionality enabled (most have this feature, like the latest versions of Windows or iOS).

4. Be Very Careful With Downloads

If you use sharing programs or usually get files from sites that specialize in downloads, be aware of what to download. At the end of the download, check if the file has any strange characteristics, for example, more than one extension (such as cazuza.mp3.exe ), too small size for the type of the file, or suspicious description information. Many digital pests pass for music, videos, photos, applications, and the like to deceive the user. In addition, always scan the downloaded file with antivirus software.

Also, watch out for sites that ask you to install programs to continue browsing or enjoying some service. Be wary of offers of "miraculous" software, capable of doubling the performance of your computer or increasing the speed of the internet, for example.

When obtaining software that, at first, is legitimate, you must also be careful with its installation: during this process, the application can pre-schedule the joint activation of other programs, such as browser bars or supposed security applications. Therefore, follow all installation steps and reject any offer of this type.

5. Fake Emails and Sms Are Still Very Common

Did you receive an email saying that you have a debt to a telephone company or an SMS stating that one of your documents is illegal? Or, does the message offer you prizes or photos that prove to cheat? Is there a subpoena for a court hearing there? Does the email ask you to update your bank details? It is very likely (very likely) that it is phishing, that is, a false message, so ignore it.

If the message contains texts with spelling and grammatical errors, making tempting offers or informing a link other than the one indicated (to check the real link, just hover the mouse cursor over it, but without clicking), be suspicious immediately. If in doubt, contact the company or entity whose name was involved in the email.

6. Avoid Accessing Dubious Websites

Many websites contain scripts capable of exploiting Internet browser flaws on their pages. Others do not have scripts but try to convince the user to click on a dangerous link, to register with a suspicious service, and so on. It is relatively easy to identify these sites:

  • Its theme is very appealing, exploring adult content, hacker or gambling, for example;
  • The website automatically opens several pages or windows with appealing advertisements;
  • Your address (URL) is often complex or different from the site name;
  • The site displays advertisements offering free prizes, benefits, or products;
  • Require download of a program or registration to finish determines action.
  • When you come across sites with these or other suspicious features, do not continue browsing.

7. Don't Reveal Important Information About Yourself

On social networks (Facebook, Twitter, Instagram, among others) or any service where a stranger can access your information, avoid giving details of the school or college you study, the place where you work, and especially where you live. . Also avoid making available data or photos that provide relevant details about you, for example, images showing the facade of your home or your license plate.

Never disclose your phone number openly by these means, nor inform the location where you will be in the next few hours or a place that you regularly visit. If this data is directed to your friends, please notify them in a particular way, as any and all relevant information about you may be misused by malicious people, including to locate you.

8. Be Careful When Registering Online

Many sites require you to register to enjoy their services, but this can be a "trap". Now, if a website asks for your credit card number without you intending to buy something, the chances of it being "stolen" are great. In addition, your information can be delivered to companies that sell subscriptions to magazines or products over the phone, for example.

To make matters worse, your email or phone number can be inserted into spam or marketing lists.

So, before registering on websites, do an internet search to check if that address has a record of any illegal activity. Also, assess whether you really need to use the services offered there.

9. Use 2-step Verification

Several companies, such as Google, Apple, and Microsoft, offer in their services the option of two-step verification ( two-factor authentication ). With it, you must enter a code after logging in, otherwise, you will not have access to the service, even if you enter the password correctly.

In many services, the code is sent by SMS. But the code can also be issued by token-type devices (such as those used by banks) or applications like Google Authenticator and Microsoft Authenticator. These tools are available for Android and iOS and are more secure than SMS, so choose them whenever possible.

The advantage of two-step authentication is that if your password is discovered by a third party, that person will not be able to access your account because they do not have the authentication code. Make sure the services you use offer this feature.

10. Public Wi-Fi Networks Can Be Dangerous

Take great care when accessing public Wi-Fi networks, especially those that do not require a password. Some can be "bait" to capture data from devices connected to it. Others may direct you to fake websites. Therefore, give preference to networks of known companies.

One way to reinforce security when connecting to public networks is to use a VPN ( Virtual Private Network ). This type of service hides your IP address (even if it is IPv6 ) and reinforces your privacy.
