There might be times when your desktop antivirus has turned a zombie, rendered practically useless by some trojan or a virus. The possibility of such a thing happening is very rare, but still having an option to cross check is always good. An online virus scanner should never be considered a substitute for an installed antivirus scanner. But if you suspect your installed desktop antivirus is missing a threat or you simply want a second opinion, an online scanner can be a valuable adjunct to security. The list below introduces some of the best online antivirus services and is in no particular order.


Top 10 Free Online Virus Scanners

1. Kaspersky Free online virus scan

Kaspersky Anti-Virus is one of the mostly used Antivirus software and has got a Free online virus scan tool as well. Kaspersky provides a free File Scanner which will help you to scan suspicious file on your machine. The online virus scanner tool is extremely fast and efficient. It can be configured to scan individual files, folders, and drives. Detection only.

2. Bitdefender Quickscan

BitDefender QuickScan combines intelligent local scanning and in-the-cloud scanning to create an advanced online antivirus scanner which detects e-threats in memory. BitDefender QuickScan is very light on the computer memory, it requires only a very small browser plugin for client-side tasks. Detection only.

3. Trend Micro Housecall

Trend Micro’s Housecall is one of the few tools in our Top 10 Online Scanners to offer cleaning or deleting of infected files. If you are being attacked by popular viruses, than you need to scan your PC with Trend Micro Housecall. This scanner easily finds and kills popular viruses. But on the other hand, rare viruses usually aren’t found by this scanner and Trojan horses escape too. Updates and detection are not quite as reliable as the Kaspersky options above. Select Housecall only if cleaning or deletion is desired.

4. FREE on-line scan service is another free online scan service, which will check the uploaded files for viruses, trojans, backdoors, spyware and other malware using different antivirus engines. You can upload any type of files and there is 10Mb limit per file. VirSCAN supports RAR and Zip decompression, but there should be less than 10 files in the archive. Detection only.

5. F-Secure Online Virus Scanner

F-Secure’s free Online virus scanner is capable of finding and cleaning viruses and trojans. But ability to clean the virus is not guaranteed. It works on Internet Explorer 6 or newer with ActiveX and Javascript enabled, or Firefox 3. There are different options available, like ‘Quick scan’ and ‘Full scan’. Detection & cleaning.

6. Windows Live OneCare Safety Scanner

Windows Live OneCare Safety Scanner is the only scanner which works with Windows Vista. It perfectly detects popular viruses, but most of the spyware, Trojans, rootkits and other pests are not detected. And it only works with Internet explorer. By the way, its not completely free. They have a free trial and an upgrade costs $49.95. Detection Only.

7. Virustotal Online Virus Scanner

Virustotal is a free service which can be used to analyze suspicious files and facilitates for quick detection of viruses, worms, trojans and all other kinds of malware by antivirus engines. You can submit single files only to Virustotal, via their online scanner or by email. File size must not exceed 5Mb. The file is scanned by around 30 well-known virus scanners and results reported for each. Detection only.

8. Panda Active Scan

Panda active scan is a free tool for detecting and eliminating viruses from your computer. It installs as an ActiveX control in your Web browser (Internet Explorer 4.0 or higher). Another good thing is that it scans our e-mail too. But on the other hand, this scanner doesn’t perfectly detect Trojans and backdoors. Detection and cleaning.

9. FortiGuard Center Online Virus Scanner & Submission

FortiGuard Center can be used to discover a suspicious file on your machine, or suspect that a program you downloaded from the internet might be malicious. You can use the free virus scanner to scan the files present in your computer for viruses. Only one file of up to 1MB can be checked at one time. You can also submit sample files for analysis in their research labs. Detection only.

10. Jotti Online Malware Scan

Like Virustotal, Jotti returns scan results for several different scanners. The scan engines used by Jottie differ from those used by Virustotal and thus it’s often worthwhile to use both. Detection only.

    Great list…

    I have used panda in the past. Yeah it will be second line of defence.

  • Madhur Kapoor

    Thats a great list. Sometimes i do need to check my files online as you cant always rely on your AV

  • Ricky

    Great list buddy. Although i never used any of the above it will be of some help when the desktop antivirus fails. I also recommend to use as it supports multiple antivirus scanner at a time. According to me it is the best online AV scanner.

    • ajay

      i am new in this field can u please tell me which is the best antivirus for on line scaning

      • Raju

        Try Kaspersky, its really good

  • mohan

    i know some of them and i tried that also thanks for rest source to scan online,

  • Suneel

    I am afraid to go to Norton Security Scan guys. We know how Norton makes our systems crawl. I do not wish Norton again to be suffocating and choking my system.

    Good list to go through.

  • Afrodaesia

    I’ve tried Kasparsky, BitDefender and Esset Nod32 on-line scan. The first two were fine, the last one took almost an hour(way too long for a tool that only detects!). BitDefender’s quick scan really lasted only 30 seconds(scans only the active processes) as they say.

  • Ajith Edassery

    Kaspersky has been my personal favorite – damn fast scanning and actually it catches the most unexpected stuff.

    Norton and McAfee suck big time!

  • GreenEyesLucy

    Since now I’ve being trying only BitDefender because I didn’t need another antivirus. I’m very pleased by the speed of scanning and not only. It has lots of important features for every navigation on the internet and not only. Try it and you’ll never get disappointed!

  • Michael Aulia

    Great lists! Too bad most the popular ones only give a free scanning and persuade you to buy if it detects a virus on your computer :) Well I guess that’s how the guys make money

  • Preetam

    Kaspersky FTW

  • Atul

    fottiguard and Jotti new to me

  • Anish K.S

    7,9 and 10 first time to me. its a nice list.

  • cyberbob

    Really nice collection you have .I’m personally using Eset Nod on desktop and online both and its awesome

  • Virus Removal

    Great article but a little outdated. Maybe you could consider updating it with some of the newer online scanners now available.

  • prajith

    I used this extension which was available for the Chrome browser. It’s pretty nice and fast. But I went back to Hitman Pro as it includes Gdata which has Bitdefender and Avast. HMP also has several other scanners as well and does a scan pretty fast.
