Antivirus software plays a central role in the proper functioning of our computer systems. In this digital age, our computers are increasingly exposed to malware and cybercriminals. And antivirus software acts as a shield and protects our system from such vulnerabilities. An antivirus program inspects data from web pages, applications, software, files – drifting over the Internet to our computer systems. It further inspects for known threats and monitors the behavior of all programs, highlighting any suspicious behavior.

Why is an antivirus blocking your activities?

The answer is simple, it wants to prevent computer viruses and other malware from entering your system. Viruses and malware are designed to give criminals access to their victims’ devices. Malware has the potential to steal your login information, use your system to send spam, crash your computer system, and give cybercriminals immediate access to your devices and the information stored on them. In some cases, malware can give the hacker the ability to monitor and control your online activities.

All in all, if a hacker manages to enter your system through this anathematized malware, they can break into your privacy, putting you at greater risk. Basically, your antivirus tries to protect your privacy.

So if you are unable to open a website, if you have trouble downloading or installing software, if you have trouble installing system updates, if you cannot access to the camera or the internet, your antivirus might be responsible for this somewhere.

Antivirus blocks a program, downloads, etc.

To keep viruses and malware away from your system, the antivirus software you use may prevent the program from performing these functions.

It may look like a problem and you have to accept the fact that there is no specific solution. With increasing vulnerabilities in the online world, securing your system is of the utmost importance. Antivirus blocking these functions is one of the precautions you need to take to be safe.

Check firewall exceptions:

Firewall and antivirus are designed to prevent potentially harmful programs from entering your computer. If your browser is not added to the firewall exceptions list, your Internet access may be blocked. In such circumstances, you will need to check firewall exceptions and your antivirus configurations. Here we take Windows Firewall as an example:

  1. Open Control Panel in Windows 10.
  2. Go to System and security and click on Windows Defender Firewall.
  3. In the left panel, click Allow an app or feature through Windows Defender Firewall.
  4. Make sure the box Google Chrome is checked on the list.
  5. Save changes.

Reset antivirus settings to default:

Sometimes an antivirus or a firewall blocks the Internet because the user has interfered with the applied firewall on his own or has changed some settings. In such a case, resetting antivirus settings to default helps.

Reset everything to its defaults and restart your system.

Disable firewall/antivirus:

Disabling the antivirus is one of the common actions users take to fix the firewall blocking internet/Wi-Fi issue. If you are a Windows Defender Firewall user, you can go to Control Panel > System and Security > Windows Defender Firewall > Turn Windows Defender Firewall on or off and then turn it off.

Note that disabling your security software makes your PC vulnerable.

One of these tricks may work and remove the “Your Internet access is blocked” error.

2]Antivirus blocks the camera

Virus blocking

The first thing you can try here is to temporarily disable the antivirus software and then try using the camera. If your camera is working fine, antivirus was the culprit. To avoid this in the future, you will need to add a new exclusion in your anti-virus software. If you’re using Windows Defender, here’s how:

  1. Open Windows Defender Settings.
  2. To select Protection against viruses and threats.
  3. Go to Virus and threat protection settings
  4. Now click Add or remove exclusions.
  5. Select the application for which you want to have access to your webcam.

So if your camera is inaccessible due to antivirus, this solution might work.

Normally, when the web camera is not working, the user should try to update or reinstall its drivers first. Sometimes updating Windows 10 or removing an update after which the cameras stopped working also does the job. In most cases, these general solutions related to the built-in or external webcam should fix the problem. If he does not follow the steps above.

3]The antivirus blocks the installation of programs

Sometimes users may encounter an issue where their antivirus program is preventing the installation of apps due to a security risk. This is most likely due to a feature preventing the setup.exe file from downloading and installing the necessary files.

You can temporarily disable the antivirus program and try to reinstall the program again. It is important to note that disabling antivirus and installing software is entirely at the user’s risk. Once whitelisted, the .exe file puts your system at risk. It is therefore crucial to act with caution, act only if you are sure about the application or program. This is a temporary solution, for a permanent solution add exclusions for .exe files.

Follow these steps to add exclusions on Windows Defender:

  1. From The start menu open Windows Defender
  2. To select Protection against viruses and threats.
  3. From options, tap Virus and threat protection settings.
  4. Under the Exclusions section, select Add or remove exclusions.
  5. Click on Add an exclusion.
  6. Select the folder or file you want to exclude.
  7. Confirm selection.

This should solve your problem. But always remember that if you whitelist an EXE file, your computer may be in danger. So be careful with this hack.

4]Antivirus blocks emails

Windows 10 comes preloaded with built-in email support. Thus, these security programs can scan most of your incoming/outgoing emails. This security feature is very important but can sometimes trigger issues by blocking your emails for no reason. What happens here is that without scanning for possible threats, the antivirus blocks all incoming and outgoing emails by default.

In this case, the user will need to re-enable the email client functionality. And like most fixes, adding an exclusion or setting a new rule in the antivirus firewall works.

Please note – Depending on your anti-virus software, the steps for performing these fixes may vary. Please refer to your antivirus documentation.
