Hi all. So my GF installed one of the those evil "Adobe Flash Updates" I've cleaned it up (Avast and Malwarebytes)... I think. but! Now We keep loosing the ethernet connection. Every other computer in the house and we have a few work on ethernet but her iMac will not hold the connection. I renew DHCP and it assigns it, but then when I check a few hours or a day later it's blank again. The Wifi works perfectly, and I've reset the router a bunch of times which fixes it for a day or two but then it's back. Checked the usual places for Viruse/Malware no startup, no plugins Doesn't matter Safari or firefox. Cable seems fine, and even switched the ports on the router. Just in case. NADA! Any ideas? Getting annoyed I can't figure this out or find a permanent solution. thanks for any suggestions.
