Watchdog Anti-Malware is a smart tool which uses multiple antivirus engines to detect threats your regular security software might miss.
It's all very easy to use. To get started, just select the "Smart" (quick) or "Deep" (thorough) option, click "Scan", and watch as Watchdog Anti-Malware goes to work.
The program crawls over your hard drive, and when it finds something suspicious, passes a fingerprint (not the whole file) to its cloud scanner for further analysis.
Watchdog Anti-Malware's "Cloud Scanning Platform" then checks your file using multiple antivirus engines, ensuring you'll detect threats that individual packages might miss, before returning its verdict to the program.
You don't have to worry about any of the technicalities, fortunately - all you'll see is a report where threats are listed as they're discovered.
When the scan is complete, you can browse the report, choose to delete individual items, quarantine them, maybe exclude them if you're sure they're safe, before cleaning up your entire system with a click.
Watchdog Anti-Malware also offers simple real-time protection, analysing files before they're executed, and running a quick "Smart Scan" when your system starts. This worked well for us, but if you don't need that level of protection then it can be tweaked or disabled in the Settings dialog (you might run a Smart Scan every Monday, for example).
