Hello... Running Windows 7 64 bit. Doing regular maintenance on the computer, I found this folder (System32\DBBK) which I cannot identify. Created Monday, last week Dec. 5th, it contains 1622 files ranging in size from 1KB to 844 KB. All files have no extension with seemingly random filenames such as: C621FB6BF9741AA18E55377FDD2CE96F and 4F6E72B34ED3DC53DCC5E8708E60B61F. All files have a fairly consistent date stamp just after creation of the folder itself. Total contents is 3.42 GB. Can randomly open different files with notepad but don't understand the contents. In addition, there are two text files created shortly afterwards in the system32 folder, PHOOKSmf.txt and PHOOKSmf2.TXT which seem to be lists of various drivers and other Windows information. Also, some of the files in System32\DriverStore have modified timestamps corresponding to the same time frame.
System restore is not an option. Windows updates were not done that day. I may have run some sort of security software but don't remember. A Google search for more information points to various forums indicating presence of Trojan infection.
Would appreciate help in identifying this situation and whether these files can be safely deleted or disinfected if necessary. Will await response before attaching anything.
