22 лучших бесплатных антивирусных сканера по требованию

Stinger — это бесплатный портативный сканер вирусов по требованию от тех же разработчиков, что и программное обеспечение McAfee Antivirus. Его цели сканирования включают запущенные процессы, загрузочные сектора, ключи реестра и руткиты.

Вы можете создать пользовательское сканирование с помощью Stinger, чтобы просто искать в определенных каталогах и / или жестких дисках, или полное сканирование, которое просматривает все. Вы можете увидеть полный список угроз, которые можно найти из включенного  списка угроз .

Stinger может быть настроен для восстановления, создания отчетов, переименования или удаления вредоносных программ после обнаружения. Если вы знаете хэш файлов, которые вы не хотите сканировать, Stinger позволит вам составить их список, чтобы сканер пропустил их.

Размер загружаемого файла составляет около 15 МБ и не требует установки, что позволяет запускать Stinger с флешки или внешнего жесткого диска.

ClamWin Free Antivirus — это бесплатный антивирусный сканер по требованию, который можно установить в Windows или запустить со съемного USB-накопителя.

ClamWin Free Antivirus может сканировать только системную память, чтобы найти вирусы, которые в данный момент работают, или сканировать всю файловую систему на наличие вредоносных элементов. Вы можете выбрать сканирование всего диска на наличие вирусов или только определенного файла или папки.

Запланированные проверки поддерживаются в ClamWin Free Antivirus, а также интеграция с Windows Shell, оповещения по электронной почте, исключения файлов и сканирование электронной почты Microsoft Outlook.

Устанавливаемая загрузка для ClamWin Free Antivirus составляет около 150 МБ.

Dr.Web CureIt! это то же самое программное обеспечение, которое находится в загрузочной   программе Dr.Web LiveDisk , но работает в Windows, а не с диска. Это полностью переносимый антивирусный сканер, что делает его отличным способом предоставления бесплатных возможностей поиска вирусов без необходимости устанавливать что-либо.

Вы можете сканировать загрузочные сектора, память, папку Windows, временные файлы, точки восстановления системы, руткиты или пользовательские файлы и папки.

Пока Dr.Web CureIt! является портативным, то есть вам не нужно ничего устанавливать на свой компьютер, размер загрузки относительно большой — около 180 МБ.

eScanAV Anti-Virus Toolkit — это полностью бесплатный портативный сканер вирусов для Windows.

Он проверяет наличие в системной памяти программ-шпионов, рекламного ПО, клавиатурных шпионов и аналогичных потенциально опасных элементов. Антивирус eScanAV также может сканировать отдельную папку или весь диск.

You have the option to just scan without repairing any files, as well as the option to include scanning archive files.

You can also use eScanAV Anti-Virus Toolkit to view and terminate connections to the Internet, which is useful if you suspect a malicious program is accessing the Internet.

Updates can be performed because MWAV installs itself to a temporary location while you use the program. Though this is also a downfall because it means you have to run the setup file again if you wish to use the program in the future, given that all the files were unloaded to a seemingly undisclosed location on your computer.

Something else a bit bothersome about this program is that it displays an advertisement every time you close it.

The file is around 280 MB, so downloading MWAV may take some time.

Microsoft Safety Scanner is a free on-demand portable scanner from Microsoft that checks for and removes spyware and similar malicious files.

You can run a quick scan to check only critical areas where viruses may be resting, a full scan to check every file and folder on your PC, or a custom scan to couple a quick scan with a scan of any other folder of your choosing.

The installer file for Microsoft Safety Scanner is 140 MB and runs as a portable application.

Norton Power Eraser is a portable on-demand free virus scanner that’s just 10 MB in size.

The featured virus scanning function in Norton Power Eraser is activated with the main button called Scan for Risks on the first window of the program. This requires a reboot as it scans for rootkits. 

Choose Advanced Scans for other scanning methods. You can scan a file or folder with the Reputation Scan, which performs a cloud lookup on the data. This requires an active Internet connection so Norton Power Eraser can upload the necessary information to the Internet. 

Another method is the regular System Scan option, which scans the current Windows operating system for viruses. The third and final option is similar to the second and is only effective if you’re running more than one Windows operating system. If that’s the case, you can use the Multi-Boot Scan method to select the other OS that should be scanned.

Sophos Virus Removal Tool is an on-demand free virus scanning tool for Windows that scans for viruses in the file system and memory.

Every time the program is started, it automatically begins an update to be sure its definitions are current, which is nice.

You won’t find custom settings in Sophos Virus Removal Tool like file/folder exclusions, scheduled scanning, or context menu integration like similar products offer. However, the scan is thorough and the program lets you remove any viruses it finds when it’s finished, which is still helpful.

The program has to be installed to be used, and is around 200 MB in size, so the download may take some time to complete.

Options are available to exclude files and folders from a scan and to delete or restore quarantined items that Normal Malware Cleaner has found.

The download size of Norman Malware Cleaner is around 300 MB. This is quite a large sized file, but that’s because the program isn’t installed to your computer, but instead ran as a portable program.

Comodo Cleaning Essentials is a portable virus and rootkit scanner. You can run a smart scan to scan critical areas of the computer or do a full or custom scan.

If you choose a custom scan, you can use Comodo Cleaning Essentials to scan in the memory, critical areas and boot sector, hidden registry objects and services, and/or hidden files and folders.

You can even choose to disable the virus scan so you can check for malicious items in the memory only, for example, instead of searching through the whole computer.

Advanced settings are available such as scanning in archives, excluding large files from a scan, scanning for suspicious MBR modifications, and enabling the creation of restore points before running a scan.

Comodo Cleaning Essentials also includes Autorun Analyzer, which is used for viewing all the programs, drivers, scheduled tasks, and other things that launch when Windows starts. Also available is KillSwitch, which lets you shut down running programs, processes, and network connections.

If you can’t get into Windows to start a scan, you can even run this program using Comodo Rescue Disk.

The developers of Panda Dome also have an on-demand tool for Windows that can scan for viruses, called Panda Cloud Cleaner.

This download is under 40 MB in size and scans in the registry, system memory, and other common locations where malware could be hiding. You can also scan individual files and folders, shut down all running processes, unlock files, and submit suspicious files to Panda for analysis.

If the program isn’t helping, the same developers also have Panda Cloud Cleaner available from a bootable scanner, called Rescue ISO, that you can run before Windows even starts.

Zillya! Scanner is a free on-demand portable virus scanner for Windows from the same developers as Zillya! Antivirus.

You can run a quick scan to find viruses in sensitive folders, a full scan to scan every area of a drive, or a custom scan to choose particular folders, files, and drives to scan.

When running a custom scan, you have the option to just check potentially dangerous file types for viruses so Zillya! Scanner doesn’t have to scan every single file.

The Zillya! Scanner setup file requires 190 MB of free disk space.

Multi Virus Cleaner 2011 is a very simple and easy to use on-demand virus scanner.

Only a few settings are found in this program, which makes it much less confusing than most other virus scanner software.

One option is whether to prompt you when a malicious item is found or to disinfect it automatically.

The other settings are simply where you want to scan, like a quick scan against system files, a full scan for all areas of the local drive, a deep scan, or a custom scan.

You can also scan the memory to check all the running processes for worms, Trojans, and spyware.

There are absolutely zero custom settings in F-Secure Online Scanner. If it finds a virus, it’s removed without question and doesn’t prompt you to decide to keep it.

Ashampoo Virus Quickscan is just that — a quick virus scanner. It’s completely portable with a small size and scans awfully fast, completing in just a few minutes when I tested it.
