Could the restore points be what's eating up my space? bearing in mind that the last 2gigs was from ESET and so not included in the problem? I will del restore points.
Depending on how many restore points you have and how big you make them (the max size is 12% of total HD space) they can definitely eat up some space.
To remove the old restore points and set a new one, do the following:
- Go to Start > All Programs > Accessories > System Tools > System Restore
- Select Create a restore point, and Ok it.
- Next, go to Start > Run and type in cleanmgr
- Make sure the C:\ drive is selected and click OK. If your computer's Hard Drive is not located on C:, change it to the correct drive letter then click OK.
- Select the More options tab
- Choose the option to clean up system restore and OK it.
- This will remove all restore points except the new one you just created.
I'm confused, I thought the problem was word acting as a server, not ZA??
I just wanted to make sure you had the latest version and were fully updated with ZoneAlarm.

Those links you got from ZoneAlarm did help.

I noticed the following words in each link: No breach in your security has occurred. Your computer is safe. And looking over the ZA links for Winword.exe and engine.exe, you have the legit versions of both. When the allow/deny message pops up for those two programs, you can go ahead and click Allow to allow it.
