title: Magento Fatal error: Class' Varien_Data_Collection_Filesystem' not found
body: <p>Checking the cause of the error, the Filesystem.php file is is renamed to Filesystem.php.suspected. Manually renaming it back to Filesystem.php fixes the issue but everyday we need to manually rename it since it is constantly being renamed back to Filesystem.php.suspected.</p>
  
  <p>I've googled as to what causes the error but still no luck.
  I am quite sure that there is something that is renaming this file but don't know where to start since i'm fairly new to magento.</p>
  
  <p>Magento ver. 1.9.1.1</p>
