Are emails scanned for viruses?
Blocking of executable email attachments/virus scanning
All email sent to or from UCL addresses is scanned for viruses. If a virus is found, it is removed and the message forwarded to the recipient with a warning that an attachment has been removed. The sender of the message is also warned.
In addition, certain file extensions that are commonly used by viruses or that are capable of misuse, for example, .exe , are automatically blocked. This measure is necessary to stop new viruses that are not detected by the virus scanning system at the time of sending.
Type of files blocked
The following file types are blocked by the virus scanning system. Any .zip files or other archives containing any of these file types will also be blocked:
|.asx||Windows Media Audio / Video|
|.bas||Microsoft Visual Basic class module|
|.cmd||DOS CP/M Command File, Command File for Windows NT|
|.cpl||Control Panel Extension|
|.isp||Internet Service Provider Settings (Microsoft)|
|.jse||Jscript Encoded Script file|
|.pif||Windows Program Information File (Microsoft)|
|.scf||Windows Explorer Command|
|.scr||Windows Screen saver|
|.shs||Shell Scrap Object File|
|.vb||VBScript file or Any VisualBasic Source|
|.vbe||VBScript Encoded script file|
|.ws||Windows Script File|
|.wsc||Windows Script Component|
|.wsf||Windows Script file|
|.wsh||Windows Script Host Settings file|
If you need to send a file of one of these types, there are several possible workarounds.
1. Rename the file extension to something else
For example you could rename 'file.exe' to 'file.ex_'. The recipient will have to rename the file back to the original extension. To rename a file in Windows, simply right-click on it and click 'Rename'.
However, by default Windows hides file extensions, so 'file.exe' may appear simply as 'file'. In order to rename the file extension you must first make sure it is displayed. to do this, click Start, My Computer, then click Tools, Folder Options. Click the View tab and untick Hide extensions for known file types.
2. If the content is available on the internet consider providing a link to the content for the person to download.
3. Place the content inside a .zip archive which is encrypted and provide the recipient with the password to open the .zip archive.
