Comodo Time Machine (CTM) is a powerful system rollback utility that allows users to quickly restore their computers to an earlier point in time. CTM 'snapshots' are a complete record of your entire system (including the registry, critical operating system files and user created documents).
I had to uninstall it. Heavy on resources, very slow to boot-up, and two of my start-up programs wouldn't load. Seemed similar to that back-up software that came with Norton Sys. Works 2003 (can't recall the name and it's not important). I didn't like it either for the same reason.
It may be Ok for some without other types of back-up.
Sorry it didn't work-out for you, Alan -- thinking I'll forego trying it after your experience. (The Norton System Works 2003 programs are Backup Wizard &Restore Wizard.)
