My avast antivirus is not updating
I wasn't aware that Windows Defender was part of the package and so I went to look for an antivirus program.
I like Chome browser and read that Avast was the best option with this browser.
More then likely there is a internet security firewall driver in place put there by Avast to scan incoming/outgoing traffic for malware activity.
If you did not install the AV all the way, that driver may still be in place & is preventing a connection.
Also, anytime you uninstall a AV, be sure to use the AV's uninstaller to make sure you get it completely out of your system.Navigate to your Local Area Connection Status, click on properties & see if such a program is still there (i.e., Avast Internet Security Firewall driver).If such a program is listed & still checked, uncheck it & see if you can get online.I also ran Malwarebytes but it came up with nothing.I don't know if I have a virus or not, but ever since I installed Avast my PC is is being prevented from connecting to the Internet so its rendered useless!
