BitDefender’s QuickScan (last updated April 7, 2011), is a Firefox, and Chrome add-on, built around cloud based technology (a continuously updated malware database and scanner, hosted on remote servers), making it FAST! FAST! FAST!
Following installation of the add-on, QuickScan sets a quick launch Icon in the Browser Toolbar for easy access. (Firefox 4 shown)
The following screen shots show QuickScan in the process of scanning critical files and modules, on my Win 7 machine.
Elapsed time 10 seconds!!!! That meets my definition of FAST! I run QuickScan daily, and a 10 second scan completion is fairly typical.
My Internet connection speed is – 16 Mbps (download), and 1.5 Mbps (upload). Your results may vary, depending on your connection speed.
Following the scan, you’ll have access to a full report. The following screen capture is only a partial representation of the report, (it’s just too big to insert in this article). Click on image to expand to original.
Fast facts:
Very fast scanning
Runs online from any Internet connected Windows PC
Based on BitDefender anti-malware technologies
Detects running malware
Detects hidden threats (rootkits) and keyloggers
Scans:
Processes
Network activity
Autoruns and critical files
Browser plug-ins
Note:
This add-on is not a replacement for active antimalware protection.
No cleaning capabilities are included in QuickScan, so if you encounter a positive indication of a malware infection, use your onboard antimalware application to clear it.
Takeaway:
Today’s malware is quite capable of shutting down onboard antimalware applications, while allowing the user to believe the application/s are fully functional. A simply scan with QuickScan can provide an early warning of such activity.

Very good ! 65s on first scan & around 11s thereafter on 32-bit xp with double your connection speed & 961 files
Couldn’t see the icon because it installed in the ‘navigation’ toolbar which I don’t use ~ moved it to ‘menu’ toolbar & all’s well
Thank you
Hi Michael,
I should have pointed out that fact. Subsequent scans are considerably faster than the initial scan – glad you made the point.
I’m envious of your connection speed, BTW. 🙂
Best,
Bill
in FF4 ~ icon insists on moving back to the navigation bar between browser sessions. I’ve also noticed the WOT icon doesn’t like to be removed from the navigation bar either
FF is beginning to remind me of Windows explorer weirdness ~ I’m going for a lie down 🙂
Hi Michael,
I find it astonishing that many experienced users are reporting numerous problems with Firefox 4, yet the “paid” tech press has all but ignored the issue. I suspect that puffery pays dividends.
Best,
Bill
