How often does rootcheck run?

The rootcheck scan frequency is configurable with frequency. By default it runs every 2 hours.

How does rootcheck know the rootkit files to look for?

The rootcheck engine has databases of rootkit signatures: rootkit_files.txt, rootkit_trojans.txt and win_malware_rcl.txt. Unfortunately, the signatures are out of date.

Does rootcheck inspect running processes?

Yes, rootcheck inspects all running processes looking for discrepancies with different system calls.

What about hidden files?

The rootcheck engine scans the entire system comparing the differences between the stat size and the file’s size when using the fopen + read calls. If any results do not match, you may have malware installed.
