Free Antivirus Scanners

A list of all the FREE and TRUSTED
online antivirus and spyware scanners.

Editorial: I created this page when my laptop was infected by a virus, and I had to search for the major antivirus tools that are free and do not require installation. This page contains the results of the search and is a valuable resource for users that try to remove a virus from their computer or they just want to do a thorough antivirus scan. We all hope that we will never need such information, but it good to have a link to this page in our favorite bookmarks. You may also want to send this link to your friends, just-in-case.

Source of the list: Free Antivirus Scanners on 24Hsoftware.com


These online antivirus scanners are offered for free, so that you can make a better decision on which antivirus software you should buy.

Most of these tools will ask you to install an "ActiveX" control. This is safe, since the list is restricted to contain only the official sites of major antivirus software companies.

Modern viruses are able to disable some of the antivirus programs. It is therefore recommended that you run as many as possible of the tools below to find a virus that is able to hide itself from the specific antivirus tool you are using.

After finishing with the "Free Antivirus Scanners", please go to the "Antivirus and Firewall Utilities" list. These are the full versions of the antivirus software tools that you can buy and have permanent protection.

NGenFix is a Norman program utility that may be used to detect and remove specific malicious software (malware).
Note that it should not be used as a substitute for running normal proactive antivirus protection, but rather as a reactive tool to handle systems that are already infected.

By downloading and running the program below it will clean an infected system completely:

kill running processes that are infected
remove infections from disk (including ActiveX components and browser helper objects)
restore correct registry values
remove references created by malware in hosts file
remove windows firewall rules for malicious programs
NGenFix-switches
/scan Specify file/folder to scan
/exclude Specify file/folder to exclude
/run Start scanning automatically
/quiet Don�t display GUI
/log Specify log file
/noclean Skip the cleaning process
/nops Skip process scanning
/nounpack Skip archive scanning
/? List switches


System requirements
Supported operating systems are: Windows 98, Me, NT, 2000, XP and 2003
Operating systems not supported is: Windows 95
Note
To give NGenfix the best working conditions possible, we recommend that you start the computer in Safe mode before running the fix. To do this, tap the F8 key on your keyboard during startup, before Windows starts, and select Safe mode from the menu that appears.
Pressing the F8 key at just the right time may be a little difficult (after the firmware POST process completes, but before Windows displays graphical output). If the F8 method does not work, repeat the procedure, but press the F8 key more quickly, or press it several times.
On some (older) computers, the F8 key method may not work. In these Windows versions you may also configure your computer to start in Safe mode through the System Configuration Utility (msconfig).
In some cases NGenfix may require that you restart the computer to completely remove an infection

Malicious software covered
NGenfix covers cleaning of all known variants of the following families up to:

TrojanScan (free online scan) »

TrojanScan (free online scan)

Trojan horses are a huge security threat. A Trojan is a program that enters your computer undetected, giving the attacker who planted the Trojan unrestricted access to the data stored on your computer. Trojans can transmit credit card information and other confidential data in the background. Trojans are often not caught by virus scanning engines, because these are focused on viruses, not Trojans. Catching such threats would require the use of a Trojan scanner (a.k.a Trojan cleaner, Trojan remover, anti-Trojan).

Scan your system for trojans using this free online trojan scanner. Anti trojan software will allow you to scan and stop trojans from entering your network. A trojan remover is a vital addition to your network security toolbox, allowing you to clean a trojan virus which has already been installed in your system.

Requirements for the test:
Windows 2003 Server, XP, 2000, ME, NT 4 or 98
Internet Explorer 5.0 or later with ActiveX enabled

Webroot Free Spyware Scan Webroot Free Spyware Scan

Free Spyware Scan available from Webroot

Editor's Review:
This free scan is done by downloading and installing the free version of webroot software. If you just want to do an one-time scan, you can remove the software after completing it.
During the installation I was asked to provide an email address, but I was later able to complete the running of the program without receiving any relative email.

During my scan the tool reported:
trojan horses: infected mushroom, trojan-backdoor-dimenoc
Adware: sogou toolbar

But webroot did not give proof where exactly these components have been found. E.g. file locations or registry settings.
Other free scanners did not find these components.


The trial version only reports threads. It does not remove them.

Description from the vendor:
