I use Firefox for internet, I use Kaspersky get msg they are not comp
I like to use Firefox for my internet and e-mails. I have Kaspersky Total Security on my computer. I keep getting a message that Kaspersky cannot connect. Also that Kaspersky has been cancelled. Kaspersky tells me everything is OK and have scanned my computer several times. Why doesn't Firefox work with Kaspersky?
Check Kaspersky for updates. What is the full error message?
