Clicking on PDF files giving blank page

hope someone can help.
I can't access any pdf files, either when sent through email as attachments or on web sites, all I get is a blank white page. I have Adobe Reader 7.0. I have checked with several friends who say that they can access the pdf files I'm trying to get so it's not the files it's me.

Thinking that there was something wrong with my Adobe Reader install, I deleted it using Add/Delete Programs and installed it again, then rebooted. This did not solve the problem. So I deleted/installed/rebooted again a couple of more times. I dunno, I guess you could say that if it didn't work the first time it ain't gonna work the 5th time, but I thought I might get lucky! <shrug>

I'm using Win XP Prof and Netscape 7.2. I have SpyBot, Ad-Aware and Norton AntiVirus installed and use them.

Anyone have any ideas?
