What it is
A not-a-virus alert means your security tool found software that isn’t a classic virus but could be risky. These are often PUPs (potentially unwanted programs), adware, riskware, or dual-use tools like download managers, password tools, or IRC/FTP clients that can be abused.
Why it matters
Some not-a-virus items are legit apps from trusted sources. Others sneak in with bundles, change browser settings, or open doors for more annoying software. The alert is a heads-up to review before you trust it.
How to decide
-
Source: was it installed from an official site or a random mirror?
-
Behavior: did it add ads, toolbars, or change your homepage?
-
Need: do you actually use it, or did it arrive with something else?
-
Reputation: quick search or vendor site confirms it’s expected?
What to do
-
If unwanted: uninstall it, remove odd browser extensions, then run a full scan.
-
If wanted and safe: keep it, but watch updates and limit permissions.
-
Still unsure: quarantine first, create a restore point, and test without it.
Prevent it
-
Choose Custom install and uncheck extras.
-
Download only from official vendors.
-
Keep OS, browsers, and security tools updated.
