X=0: search for valid SSNs formatted as xxx-yy-zzzz (normal); X=1: search for valid SSNs formatted as xxxyyzzzz (stripped); X=2: default: search for both formats.
Allow heuristic match to take precedence. When enabled, if a heuristic scan (such as phishingScan) detects a possible virus/phish it will stop scan immediately. Recommended, saves CPU scan-time. When disabled, virus/phish detected by heuristic scans will be reported only at the end of a scan. If an archive contains both a heuristically detected virus/phish, and a real malware, the real malware will be reported Keep this disabled if you intend to handle "*.Heuristics.*" viruses differently from "real" malware. If a non-heuristically-detected virus (signature-based) is found first, the scan is interrupted immediately, regardless of this config option.
In some cases (eg. complex malware, exploits in graphic files, and others), ClamAV uses special algorithms to provide accurate detection. This option disables the algorithmic detection.
PE stands for Portable Executable \- it's an executable file format used in all 32\-bit versions of Windows operating systems. By default ClamAV performs deeper analysis of executable files and attempts to decompress popular executable packers such as UPX, Petite, and FSG. This option \fBdisables\fR PE support and should be used with care!
If an email contains URLs ClamAV can download and scan them. \fBWARNING: This option may open your system to a DoS attack. Never use it on loaded servers.\fR
Extract at most #n files from each scanned file (when this is an archive, a document or another kind of container). This option protects your system against DoS attacks (default: 10000)
Extract and scan at most #n kilobytes from each archive. You may pass the value in megabytes in format xM or xm, where x is a number. This option protects your system against DoS attacks (default: 25 MB)
Extract and scan at most #n kilobytes from each scanned file. You may pass the value in megabytes in format xM or xm, where x is a number. This option protects your system against DoS attacks (default: 100 MB)
