In last one or two years, many security companies have started to utilize the cloud for their purposes, for instance by keeping a large portion of a software’s database in the cloud for better and faster updating.

BitDefender QuickScan is one such app that combines intelligent local scanning and in-the-cloud scanning to create an advanced online tool which detects e-threats in memory quickly.

It is very lightweight, requiring only a very small browser plug-in for client-side tasks( including Mozilla Firefox, Google Chrome and Microsoft Internet Explorer web browsers). Unlike other online virus scanners the engines don’t need to be downloaded to your system and updated.

How to Use BitDefender QuickScan

To get started, go to BitDefender QuickScan website and click the “Scan now” button. Immediately you will see an installation dialog pop up right away to install the browser extension that’s needed to run the scan.

BitDefender QuickScan runs online from any Internet connected PC and it doesn’t slow down your PC.The scan takes less than a minute after the installation of the browser extension.

You will either see that nothing has been found, or that the tested system is infected and needs to be cleaned. It mainly detects running malwares, hidden threats (rootkits), and keyloggers.

However the application does not come with cleaning capabilities though, and BitDefender will advertise their own products on the page as the cleaning solutions. If you do not feel like paying money for a solution that could get rid of malware on your system, you could try free scanning and removing alternatives.
