Combofix has a built-in time out (expiration) feature which is there for protection against using outdated versions which may cause serious problems with your computer if used
. Thus, the date check is a safety feature deliberately incorporated by the tool's creator for that very reason. In June 2008, sUBs advised he lifted the limit when running the /U switch with expired copies of ComboFix that had passed the 10 day limit.
Without going into specifics to protect the integrity of the tool, ComboFix gives users the choice of running itself in "Reduced Functionality
" mode with limited capabilities...most of its autofixing routines are disabled. The 'Reduced Functionality
" mode protects users
who are running an older and/or possibly buggy version of the tool which may cause problems. It also serves as a way for users to create a log for review when asked for by trained experts providing instructions for using ComboFix under supervised guidance.
In some older versions of ComboFix, the expired version may no longer work properly or effectively. In newer versions, it should delete the copy on a user's computer and try to ensure no other copies of ComboFix will run on the machine until an updated copy is released.
I have not used ComboFix in years since nor have there been any recent reports that I am aware of. Most malware removal experts now use FRST
