I'm having problems with my computer freezing now and then, usually while browsing with the Opera Browser. I've noticed several events in the log but I need someone to take a look at them or to guide me in how to troubleshoot this myself. I've recently had several events saying "File-system filter Amon: released file: PortLoop" but I don't know if this is related to the freezes. Can someone point me in the correct direction? Info: Smart Security 22.214.171.124 standard settings. Auto mode firewall Windows 7 Home 64-bit - fully updated. Opera 11.60 and Opera 12 alpha (same problems with both) Reformatted the PC a month ago.
