title: adb install over usb not working
body: <p>I have a bash script running in work which automates the install of various APK samples (some malicious, some not - for testing purposes) to a HTC Desire Z handset running Sophos AV.</p>
  
  <p>Runs well but every now and then an APK will try to install and the shell prompt will just hang at install. At the same time Sophos detects it as malicious but instead of displaying a box offering to uninstall it, it displays a box to delete it instead. Whether this is connected to the adb install issue I'm not sure but it's happened everytime.</p>
  
  <p>It appears to install ok (2539 KB/s (634874 bytes in 0.244s)) .Package size is 640k.</p>
  
  <p>I am running the command adb install -s /location/of/sample.apk</p>
  
  <p>Any ideas?</p>
  
  <p>Sorry for the lengthy post</p>
  
  <p>Thanks</p>
