Each time you send and receive attachments, Gmail automatically scans them for viruses.

If a virus is found in an attachment you've received, our system will attempt to remove it, or clean the file, so you can still access the information it contains. If the virus can't be removed from the file, you won't be able to download it.

If a virus is found in an attachment you're trying to send, you won't be able to send the message until you remove the attachment.

Gmail anti-virus faq's can be found here:

This makes firefox really freaking fast.

Please Note: you need to enter "about:config" without the quotes in the location/address box first

1. Find browser.tabs.showSingleWindowModePrefs and double click on it so it = true
2. Find network.http.pipelining and double click on it so it = true
3. Find network.http.pipelining.maxrequests double click on it and change it from 4 to 100

What do these changes do?
1. Then enables advanced tab options in your Tools/Options page
2. This enables option #3.
3. This makes FF use 8 threads to each page.. Bascially, if you thought FF was fast before, try it after this.
