It continuously scans the computer for malicious programs such as viruses, Trojans, backdoor programs, worms, malware etc. Furthermore it monitors every action executed by the user or the operating system and takes prompt action when a malicious program is detected.
Scans are flexible, allowing the user to completely scan all hard drives, or choose a customized a scan. It combines the antimalware with the antivirus giving a better protection. The heuristic scan can be turned on or off completely or partially, with three different intensity levels.
A quarantine spreadsheet layout displays all relevant information about the quarantined file, and gives a user options to re-scan, restore, delete, etc. The scheduler is fully customizable and definition files are available at Avira's web site.
