Hi,
Do not delete shortcuts manually, if you deleted shortcuts manually you may end up loosing your actual data.
Scan the infected machine with Symantec power eraser tool.

Make sure SEP client is updated with the latest definitions, all three SEP features are installed.
Make sure machine is patched with latest windows patches and service pack.
If SEP and power eraser couldn't find anything then run the SST & submit suspicious files to the Symantec for further analysis.
