Using a Supplemental Scanner Alongside Your Antivirus
Tools in this category are commonly positioned as a "second opinion" scanner rather than a full antivirus replacement. Here's the general reasoning behind that approach.
No single tool catches everything
Different security tools use different detection methods and databases, so running an occasional second scan with a different tool can sometimes catch something a primary antivirus missed.
On-demand scanners generally avoid real-time conflicts
A tool used mainly for manual, on-demand scans is less likely to conflict with a primary antivirus's real-time protection than running two full real-time engines simultaneously.
It's not a replacement for baseline protection
Relying only on manual, occasional scans without any continuous real-time protection generally leaves gaps — a supplemental tool works best alongside, not instead of, ongoing protection.
Check compatibility notes
If a specific product advertises real-time protection alongside another full antivirus, check that product's own documentation for guidance on avoiding conflicts.
