Had I the time at the moment, I might do some further ''investigation'' for you. Having said that, off the top of my head...
You said, ''Also in outlook it keeps telling me i have one more unread e-mail message than i actually have.''
I use Outlook Express, so I can't be sure of Outlook, but... when I "block an address", it will go directly into the ''Deleted Folder'', where you won't see it in your ''Inbox''. Additionally, it will show up as an unread email. (If this is your situation, look in your Deleted Folder, you should see it there, as unread.) Could this be your problem with ''one more unread e-mail''?
Just a quick thought...
Hi, i'm using win xp pro and outlook, zonelabs firewall. I'm also using a broadband router. I also use anti virus and ad aware regularly.
Been having some weird things going on with some rather important documents eg, large bits deleted, short letters turned into 500 page documents all with weird unreadable jumbled characters. Obviously this is a huge problem, and i am suspicious about it as it's the documents that are potentially important.
Also in outlook it keeps telling me i have one more unread e-mail message than i actually have.
Firstly i'm wondering if the outlook thing is a virus of some sort. As for the document tampering if that's the right word, i'm worried i've been hacked.
It's a stand alone machine also. Anyone else had problems like this? Any ideas what i can do other than just back up and stay the hell offline???
