A detection list is not a disaster report. It is the antivirus doing its job in daylight. What you do in the next hour - calmly, in order - decides whether the story ends here.
The scan finished and the number is not zero. Before you click anything dramatic, understand what you are looking at: detected and quarantined means caught and jailed. The danger window was before the scan, not now. This page is the hour after - the rescan that proves the clean, the passwords that need changing and in what order, the bank check nobody remembers, and the honest line where repeated cleaning stops working and a Windows reinstall becomes the right answer instead of another scan.
The first instinct is to empty the quarantine immediately, or restore a file because a program stopped working. Resist both for now. Quarantined files cannot run, so there is no urgency to delete them, and deletion destroys the names and paths you may need. If a program you use broke because one of its files was quarantined, that is information, not an emergency: note which file, and decide after the second scan. Legitimate software is occasionally flagged, but on a PC that was genuinely infected, most quarantined items are exactly what the report says they are.
Restart the PC, reconnect nothing you do not need, and run the full scan a second time. The restart matters because some malware only shows its second layer once its first layer is gone, and some components can only be removed while Windows is starting fresh. Read the second report against the first: new names appearing is common and not a failure - it is the dig reaching deeper. A clean second scan after a restart is the first result you can start trusting. A third appearance of the same names, especially with the same system locations, changes the diagnosis entirely - skip to the last section of this page.
Assume anything typed on the PC while it was infected may have been seen. Change passwords from a clean device - your phone on mobile data is fine - in this order:
Turn on two-factor authentication wherever it is offered. This step is unglamorous and is worth more than any further scanning, because a cleaned PC with stolen passwords is still an open door.
Look at the quarantine paths and ask where these files arrived from. The honest answers are usually ordinary: a cracked program, a free download from a portal site, an email attachment, a pen drive passed around an office. Name it, because unnamed it will happen again. Remove the cracked or bundled software, delete the installer from Downloads, and if a pen drive is the suspect, scan it before it touches any other PC. In an office, tell whoever manages IT - one infected PC is a cleanup job; the same file on five PCs is a pattern they need to know about today, not after the second wave.
Here is the honesty this topic needs. If the same threats return after quarantine, restart and rescan - or the PC shows rootkit symptoms like security settings switching themselves back, unknown admin accounts, or Windows components damaged beyond repair - stop scanning in circles. Some infections bury themselves deeper than any cleaner can reliably dig out, and a half-cleaned PC you keep banking on is worse than a rebuilt one. Back up only your documents and media (never programs or anything executable), reinstall Windows cleanly, install Quick Heal from the official site before reconnecting your data, and scan the backup as it comes back. It feels drastic because it is final - that is exactly why it works.

Keep them until you have restarted, rescanned clean, and are sure none of them is a legitimate file caught by mistake - the quarantine list also preserves the threat names and original paths, which are the most useful evidence if the problem returns or a technician gets involved. Delete them once the PC has stayed clean.
Yes, if the infection was a real one and not just adware. You cannot know what the malware saw while it was active, and password-stealing is a standard feature of modern infections. Change them from a clean device, starting with your email account because it can reset all the others, then banking and payments, and check your bank transactions for anything unfamiliar. Turn on two-factor authentication while you are there.
A threat that returns after quarantine and a restart usually has a protector: a hidden second component restoring it, a scheduled task or startup entry the cleaner cannot remove, or an infected file inside a backup or system location that keeps being restored. Note the exact names, try one more full scan after a restart, and if it still returns, stop looping. That pattern is the recognised sign that cleaning has reached its limit and a clean Windows reinstall is the reliable fix.
