So I finally decided to upgrade to Nod32 3.0. I let the installer do its thing, but after I restarted, the internet didn't work. So I uninstalled 3.0... but it still didn't work. Then I reinstalled 2.7, and it worked again! Uninstall 2.7, with or without 3.0, and the internet is disabled. I can ping my router, but that's it. Reinstall it and everything is back to normal. I tired various things; disabling my firewall, running ccleaner after uninstall, but to no avail. Anyone have any idea why this is happening? I've uninstalled NOD32 before without this problem, and I haven't done anything to the system since then. I would like to be able to uninstall my software without taking my internet out with it.
