TeamLab Online Scanner is an open source PC scanner based on Whitelisting technology. Unlike most
conventional antiviruses it collects samples of safe files. At the same time we consider all files
that launch at the Windows startup and are not present in TeamLab WhiteList to be either malicious
or suspicious. Whitelisting technology allows to find and remove malware including zero-day files,
repair damaged system files and settings.

Key features:

• Quick Scan. Checking the areas where
  the malicious software can register themselves to start securely without the user\\\'s knowing. Due
  to this selectiveness the scanning lasts only a few minutes.
• WhiteList
  verification. Checking file for the presence of its hash code in the cloud database of safe
  files.
• BlackList verification. Checking file for the presence of virus
  signature from the blacklist in it.
• Sandbox verification. Running each
  suspect file in the sandbox and analyzing its behavior.
• Zero-Day files
  detection. All the files that were not marked as malicious after the sandbox verification
  are recognized as suspicious and added to the zero-day file list.
• Rootkit
  search. Checking every autorun registry record to determine if it belongs to a hidden
  objects.
• Damaged system files and settings
  repairing.
