As far as blocking popups with Internet Explorer, I highly recommend the Google Toolbar.
It’s a free download from Google, and has the added benefit of providing special google functionality always there on your browser. It deeply amuses me that people sell software to take care of this problem.
To get it
- Go to http://www.google.com (chances are remote that you didn’t know this part already)
- Click on the ‘Services and Tools’ link that’s underneath the search field.
- Toward the bottom of the page is a section labeled ‘Google tools’ Click on the third link under that section (Google Toolbar) and follow the prompts from there.
As far as anti-virus software goes. I’ve always had good luck with McAfee, but YMMV. I suspect that Norton might not be as big of a hog on your new TR since you’ll likely be getting more memory than you had on your Thinkpad.
