PowerShell Date Check

Hi,

i am in the process of scripting the download of McAfee updates from their FTP site.  

Using PowerShell, I have created a script which pulls down the updates and then distributes them to different filers on the network.

I am trying to implement date check logic as follows.

##Delete Old Definition Files from the Share location
remove-item "\\$dest\avupdates\neta\*.*" -force -recurse

Do {remove-item "\\$dest\avupdates\EPO\commonupdater" -force -recurse
    c:\AVUpdateScripts\wget.exe ftp://ftp.nai.com/commonupdater/ -P \\$dest\avupdates\EPO -c -x -nH -r -l 0
    $file = get-item \\$dest\avupdates\EPO\comnmonupdater\*avv.gem}
    until($file.LastWriteTime -gt (Get-Date).AddDays(-2))

I use a Do Until Loop with the date check at the end.  There are times where we get files with the incorrect date,  such as out of date.

Thanks.
