I'm using windows 7 I have never had any problem with Opera before. Two days ago I turned on my computer and opened opera. Usually it goes straight to the last tabs I have open but instead on every Tab where the web page should be I have " Out of Memory" in big red letters and underneath "Either Opera ran out of memory or the process for the webpage was terminated for some other reason."
and in bold "Try reloading the page, or navigate to another page to continue."

Then I get a button "reload this page". Reloading does not work. Any Page I have more than enough memory. Clicking the opera button and opening settings/extensions/new tab etc creates a new tab with the same message.

The only thing that resolves this is to reinstall opera and it works fine until I close and reopen Opera.

I have no other issue on any browser on my computer.
I have googled the message like i do whenever i receive an error message quoting it exactly. 0 results.

Any help/advice would be greatly appreciated.

Update I believe it has something to do with my anti virus Avast. Which today started to prevent me from installing the previously downloaded opera install file and is now preventing me from downloading the file unless I turn the shields off. I really hope Opera hasn't been hacked and its just a false positive.

No I don't have my pagefile disabled.
