I am away from home on holiday at the moment. So I have left my laptops at home and I am writing this post from an Internet cafe. And this Internet cafe is stupid enough to have AVG anti-virus program installed on all of their computers. I have just tried to download both Pale Moon web browser and Firefox. And this horrible AVG anti-virus program won't let me download it. It keeps blocking the download every time I try. And I cannot do anything about it because it's not my computer. And as this Internet cafe only has Internet Explorer browser,I am being forced to use that. To write this post because their anti-virus program won't let me install another web browser. I am just glad that I am sensible enough not to install any ant-virus programs on my computers at home.And so I do not have any anti-virus programs on my computers. And I recently bought a Windows XP netbook,with Windows XP Home Edition.And I do not have any anti-virus programs on that and I do not plan to in the future. Windows Defender does not stop me installing or using any program I want to. So forget anti-virus programs,they will tell you that you have this virus and that when you don't have. And they will block programs that are not anti-virus programs. Thousands of people use Firefox and Pale Moon web browser and they are NOT spyware or a virus. Who ever invented that AVG program should go and see a psychiatrist because Firefox and programs like it are not viruses. So NEVER install any anti-virus programs on your computer. Just stick with Windows Defender and MRT-Malicious Software Removal Tool. You are better off. Windows Defender is not installed on Windows XP like it is on Windows 7 and Windows Vista. But you can install it yourself from the Microsoft website. I have got Windows Defender on my Windows XP. And I don't have any viruses on my Windows 7 or Windows XP computers. Andrea Borman.
