unable to delete malware

Ok, cool. Now you can follow the steps below, and let me know how you get on?  (taken from this KB article) 

1. Make a note of the complete file path. E.g., /Volumes/<Time Machine Volume Name>/Backups.backupdb/<Computer Name>/YYYY-MM-DD-NNNNNN/<User Name>/Library/Caches/Java/cache/6.0/8/123456-123456 
2. From the Sophos Preferences window,temporarily disable on-access scanning. 
3. In the Finder, navigate as close to this location as you can, starting from the <user name> portion. When the next level down no longer exists (or when you've found the file indicated), select 'Enter Time Machine' from the Time Machine menu item (a clock face with an arrow around the outside). 
4. Navigate to the date and time indicated by YYYY-MM-DD in the file path, and then follow the path to the detected file within Time Machine. 
5. Control or right-click the file, and select 'Delete All Backups of <detected filename>'. 
6. Click OK. From the Sophos Preferences window, re-enable on-access scanning.

Thanks,
