A two-minute quick scan that finds nothing proves almost nothing. The first scan is the foundation every later clean result stands on - it deserves the full treatment, once.
Quick Heal offers quick scans for routine days, but the first scan on a new install has a different job: to find out what was already living on the PC before Quick Heal arrived. That means a full scan, the right default action for detections, and five unhurried minutes reading the report at the end. This page covers the settings to set before you start, what quarantine actually means and why it beats delete, and how to read each kind of result without either panicking or celebrating too early.
Close the heavy programs, but do not try to make the PC faster by excluding folders from the scan to save time. Exclusions on day one are blind spots chosen blind.
When the scan finds something, Quick Heal can typically delete it, repair it if it is an infected legitimate file, or quarantine it. Quarantine moves the file into a sealed area where it cannot run, cannot spread, and can be restored if the detection turns out to be wrong. That reversibility is the whole point. Antivirus detections are very good but not perfect; a specialist tool, a crack (which you should not be using anyway), or a script you wrote yourself can be flagged. Deleting on sight turns a false alarm into lost work. Deleting also destroys evidence - if the same threat keeps returning, the quarantined sample and its original path tell you where it came from.
The recommended default for a first scan: quarantine everything detected, read the report, then decide item by item with a calm head.
The report's useful facts are the name of each detection, its original location, and the action taken. Location tells the story: a detection in a Downloads folder is an unwanted guest that never moved in; a detection inside a Windows system folder or a startup location is a resident, and a more serious one. The same threat name appearing in many places usually means one infection copying itself, not many separate attacks. Note the names down or save the report - if you later ask for help in the video comments or from a technician, those names are the first thing they will ask for, and the difference between a nuisance adware and a password stealer lives entirely in them.
A clean full scan with current definitions is genuinely good news, and it has a precise meaning: nothing the product knows how to recognise was found anywhere it looked. It does not prove the PC was never infected, and it cannot see threats that hide below the operating system or inside firmware. Keep the celebration proportionate, then do the two things that make the result durable: turn on scheduled scanning so the question is re-asked automatically, and make sure real-time protection shows as on. From here, quick scans become a sensible routine - the full scan has done the deep work they skip.

▶️ Watch Full VideoQuarantine moves a detected file into a sealed holding area inside the antivirus where it cannot run, spread or harm the PC - but it is not destroyed. That matters because detections are occasionally false alarms on legitimate files. From the quarantine list you can later delete the file permanently once you are sure, or restore it if it turns out to be a program you genuinely need and trust.
It depends mostly on the drive and how much data you have. A modern SSD with a moderate amount of data may finish in well under an hour, while a large, nearly full mechanical hard disk can take several hours. Plug laptops into power, let the scan run undisturbed, and do not judge the product by the timer - a thorough first scan is slow because it is actually reading everything, which is the point.
It is much safer, and one more step makes it solid: restart the PC and run the full scan again. A clean second scan means the visible infection is gone. Then change your important passwords - email first, then banking - because malware may have seen them before it was caught. If the same threat names keep coming back after restarts, the infection has a hiding place the scan cannot evict, and the found-threats guide in this set covers that ladder honestly.
