Hi 60 :
Perhaps there is a BitDefender file "hiding"; have you
configured your computer to "Show hidden files and
folders" ? If not, go to "Folder Options" ( it is either
accessed from "Tools" or in the "Control Panel" ), click
"View", then go down the list and check "Show hidden
files and folders", restart the computer, then use the
"Search" routine I mentioned earlier to see if it "appears".
If that does not "work", try clicking "All Programs", then
"Accessories", then "System Tools", then "Disk Cleanup";
after it gets done "analyzing", the listing at the top most
likely says : "Downloaded Program Files". If it shows more
than zero, check its box, then click "ok".
