On 3/14, both the Netzero ISP program and Avast did an update. The computer started disconnecting and refused to reconnect shortly thereafter. Netzero's guys in India have had me uninstall and reinstall, from disk and by a put-in-the-phone no.-download, their program 7 times. Also we deleted temp files, did disk clean up and shut off all security programs. The Netzero appears to not write a necessary file to disk. Is there something that got past, Avast!, Malwarebytes and Defender? Is it a cookie war? And is there a way for me to update your data base without having an internet connection through Netzero (direct call-in)? Do you know of any ailment that does this, and its cure if you do? HELP!
