Online Virus Scanner

Online virus scanner is a web based application, basically using the same engine as a mainstream antivirus product. To remove found infected files or not is the  choice of antivirus manufacturer.Of course, A User needs not only to know of having infected files, but and remove them.
Nowadays there are about 20 mainstream Microsoft sertified Online Virus Scanners.

More honest antivirus manufacturers include infection removal function into their scanners. More greedy - suggest paid assistance for it. Basically Online Virus Scanner requires Javascript enabled and Internet Explorer 6 or higher as a browser. Some Online Virus Scanners (such as Escan Antivirus Toolkit and Windows Safety Scanner) check and repair registry errors too.

Some Online Virus Scanners ( for example, Dr.Web CureIt, Emisoft Emergency Toolkit, or, again, Escan Antivirus Toolkit) are not really "online" - they are uploading into computer, but not require installation). What scanner to choose? Checking all of, i would recommend the following ones:

Escan Antivirus Toolkit (product of India!) - scan for viruses, troians , worms. Immediate infection removal. Regisry repair.  Microsoft sertified.

Emisoft Emergency Kit (former A-Squarred) - scan for viruses, troians , worms.Removal on demand. Dual (Ikarus+) infection search engine.

Dr.Web CureIt - Russian top 2 Antivirus (along with Kaspersky).Good deep check and repair.Hosts file repair, boot repair. Microsoft sertified.

Eset Online Scanner - good deep scan and repair.  Not the most quick. Must have.

VIPRE Rescue Program - a command-line utility that will scan and clean an infected computer that is so infected that programs cannot be easily run. Microsoft sertified.

F-Secure online scanner - Runs with installed antivirus. Good tool.

McAfee Labs Stinger - rootkit retriever.

Kaspersky online scanner is now under renewal, but you can use Kaspersky Virus Removal Tool. Why-not-to-have tool.

ArcaVir Online Scanner - CanHelp tool. Microsoft sertified.

Here it is. All of those are Microsoft sertified, free for check and repair. I would say, click-check-repair-forget-tool. So, if your PC is "stupid", or if you notice some suspiсious file activity - check your computer for viruses, worms, troians, adware and spyware! If you are not a user with a PC security paranoia with 5 antivirus system installed, i would reccomend you to check your computer. And remember - order, size and volume mean!
