FAQ Resource

What’s the difference between a quick scan and a full scan?

A quick scan is like a surface-level check, hitting the most common spots where bad stuff hides. A full scan is the deep dive, checking every single nook and cranny of your laptop. Quick scans are faster, but full scans are more thorough.

How often should I scan my laptop?

It’s a good vibe to run a quick scan at least once a week and a full scan every month or so. If you’re downloading a lot of stuff or visiting sketchy sites, you might wanna scan more often.

Can I use my laptop while it’s scanning?

You totally can, but it might make your laptop run super slow, especially during a full scan. It’s usually best to close unnecessary apps and let the scan do its thing without too much distraction.

What should I do if the scan finds a threat?

Most antivirus software will give you options like quarantine, delete, or ignore. Quarantining is like putting the threat in digital jail so it can’t do any harm. Deleting gets rid of it for good. Ignoring is usually only for when you’re 100% sure it’s not a real threat (a false positive).

Are free scanning tools as good as paid ones?

Some free tools are pretty decent for basic protection, but paid versions often have more advanced features like real-time protection, better malware detection rates, and customer support. It really depends on your needs and how much you wanna spend.
