Listed are FREE online virus and malware scanners that can be used to compliment the scanner(s) already installed on your PC. Some only scan individual files that you upload to the scanner; while others are full blown scanners that will scan your entire computer. Keep in mind these are not substitutes for the virus or malware scanner on your PC that have the ability to perform real-time detection. My favorite on the list is Trend Micro’s Housecall.

Great post Rick.
It’s essential to have the use of online scanners as a backup as installed versions don’t always find what they should do.
I frequently get users to scan with online scanners after completing a cleanup just to ensure that all is clean and tidy, and many knock Microsoft and OneCare, but it actually does a very good job of cleaning up.
All the best,
Colin
Colin,
Thanks for the supportive comment. It is surprising how many people are unaware of the online scanning options.

I have to give a big tip of my geek hat.. not only to the good folks who provide these free services, but to you, Rick, for assembling this list. Thank you!
Thanks Rick for the great list, I put all of them in my little black book for future reference. I check your site a few times a day. I always find something to note.
TechPaul,
As always, thanks for the “tip of the geek hat”… Coming from you means alot!
Rick
Cappydawg,
All of these scanners are pretty good; AND, useful when your scanner at the local level is not functioning properly, as a result of a malware infection, etc…
Thanks for the comment…
Rick
People shouldn’t waste Rick’s effort to spread security.
VirusTotal is great Rick!
Pochp,
Thanks for the comment…
Rick
This is an awesome compilation
Mrinmay,
Thank you for your great comment. Made my day!
Rick
Great article Rick! I also use Trend Micro when cleaning clients computers of viruses as a final cleaning. I just did one yesterday and Trend found 8 trojans/malware infections. The client had Microsoft’s Windows Live OneCare for her antivirus.
After seeing the infections, I’m not sure Window’s Live OneCare is ready for prime time. YMMV.
G,
I too, use Trend Micro from the list… A full scale, online scanner, for FREE!
Microsoft needs to stick with their operating systems and forget antiviruses, etc… Since day one they have played in the “antivirus/antimalware arena” and have never had any success; except they give people a false since of security.
Thanks for commenting!
Rick
Great list. I’ll share it with my parents (I’m a tech teacher–askatechteacher.wordpress.com). They’re always asking for stuff like this.
Worddreams,
Thank you for posting a comment… Just checked out Word Dreams. Very nice and informative blog.

Rick,
Great list and I have linked back to it, but I can’t agree with your comment on Microsoft’s security products.
I am one of 70,000 beta testers for MS Security Essentials and in my view, and in the view of a number of test labs, this product excels at both protection and removal.
Just as Microsoft has done a terrific job with Win 7, they have managed to develop a winner in Security Essentials.
Bill
Bill,
Thanks for your valuable comment. If you say it is good, THEN, it is good. I retract my previous comment about Microsoft and their attempts at security products. I really do think Microsoft has been making a turn-around with Windows 7, etc… As always, Thank you!
Rick
[...] FREE Online Virus and Malware Scanners [...]
Hey Rick,
I have to agree with Bill on MS products. Previously their poor detection rates have given them a poor name, but I am also beta testing MSE and it’s a good all rounder for protection. I’ve compared it with IOBit Security 360 and Panda Cloud and Microsoft win hands down.
With Security Essentials they have a winner and are also working alongside Alwil to ensure compatibility with Avast 5, also in Beta. Once fully released I’m sure that it will be a keeper for many users, plus it’s free
Colin,
You and Bill have me sold… I need to take a good “look see” of Security Essentials. Thanks for your input…

What an awesome list Rick!
Though I’m surprised that you included McAfee
which, even though I’ve uninstalled (like so many others), its files refuses to vanish even with
special erasing apps!
More power to WOMP sir!
Pochp,
Thanks for commenting… Keep up the great work there at Plato On-Line
