2. Free Portable Virus Scanner

Let's face it: One of the primary Windows admin tasks is keeping machines free of infection. It's inevitable. End users will open files, install cutesy apps, and go to sites they shouldn't go to. When they do these things, their machines get infected. When their machines get infected, you could wind up fighting a losing battle—unless you have the right tools.

But sometimes the antivirus tools installed on the machine just aren't enough. When that time comes, you'll be glad you have one (or more) tools on your USB drive to help you out. I've found five such tools that could certainly get you out of a serious pinch. All these tools are portable and work like champs.

ClamWin  is one of the most popular free portable Antivirus. You can quickly connect your pendrive to your computer and scan for viruses. You can choose which drive or which folder you want to scan. There are no limitations with scanning. Antivirus programs are very important to ward off viruses and other types of malicious items. If you don't want to install antivirus software, check out these free portable antivirus programs that can run without being installed. USB drives increase the mobility of documents and applications, but viruses and other threats can also infect computers through USB drives. For protection against mobile viruses, TrustPort USB Antivirus (portable) may be what you need to protect yourself and your company.

Mar 23, 2012  Hello, Is there any avast antivrus software that can install in my portable USB disk, so my disk will get protected when is attached to any PC. If you are looking for the best free USB disk security software & antivirus for Windows PC, here is a detailed list of such free tools.

Windows Update is turned off or is not set to received updates automatically. Can you update windows 7 to windows 10.

1: ClamWin Portable

ClamWin Portable (Figure A) is very much like its big brother: It's free, open source, and does a great job of disinfecting machines. ClamWin has a high detection rate, has frequently updated definitions, and provides an easy-to-use graphical interface. ClamWin doesn't offer a real-time scanner, but that's not an issue for a portable version. This is my go-to portable virus scanning software.

2: Sophos Anti-Rootkit Portable

Sophos Anti Rootkit Portable (Figure B) is one of those tools you hope you never have to use— but you know, at some point, you will. Sophos is remarkably adept at locating root kits, especially for a portable app. It scans, detects, and removes rootkits, it's free, it supports Windows XP, Vista, and 7, and it works alongside your existing antivirus. I have found Sophos reliable enough to run even while the PC being scanned is in use.

3: Emsisoft Emergency Toolkit

Emsisoft Emergency Toolkit (Figure C) is a powerful malware removal tool that can scan for, and remove, more than six million dangers to your PC. Emsisoft Emergency Toolkit has both a GUI and a command-line version, so you can scan your machine even if there are problems with the GUI. With this toolkit, you not only get the malware scanner, you get HiJackFree and BlitzBlank as well. Emsisoft offers a free download, but you can also purchase a pre-compiled USB stick.

4: VIPRE Rescue

VIPRE Rescue (Figure D) is that tool you use when your machine is severely infected. VIPRE is run in safe mode and does not depend upon a GUI tool for use. You double-click the executable and a command window opens with the scanner running (and running at blazing speeds). If you already use the full version of VIPRE, you can still run this tool if your machine becomes so infected, VIPRE won't run.

5: Spybot - Search & Destroy Portable

Spybot - Search & Destroy Portable (Figure E) is the portable version of the massively popular full Spybot Search & Destroy. This anti-malware tool does a great job of finding and removing malicious software—all from your flash drive. And Spybot has a unique feature that will help you back up your registry before you begin the scan. Should Spybot fubar your PC's registry, you'll have a backup to restore to, safe and sound.

Are you a computer expert and your less competent friends call you to solve some virus problem on their desktop?

To operate, you must bring all the software that can be useful to solve every problem. Using a USB pendrive, you can take the most important applications to save data and eliminate various viruses, such as rootkits, malware and others.

Well, if you do not have these free antiviruses yet, I’d like to show you the best, most effective portable antivirus software you can add to your collection of portable software to scan for viruses and eliminate them.

Let’s immediately see what are these 5 portable antiviruses on USB stick, which can solve various problems related to a virus attack.

The best 5 free portable antivirus

1. ClamWin

ClamWin is one of the most popular free portable Antivirus. You can quickly connect your pendrive to your computer and scan for viruses. You can choose which drive or which folder you want to scan. There are no limitations with scanning. Real-time scanning is not available. Also, scheduled scanning is disabled because it is not useful in a portable environment.

With ClamWin, you can also filter out file extensions from scans and limit the scan to even a certain number of files. Furthermore, you can send a notification email yourself if a virus is detected. The most important aspect is that the virus definition database is updated regularly.

2. Spybot – Search & Destroy

Spyware is one of those things that antivirus software sometimes can not track down. So, an antispyware is a must in your tool collection on pendrive. Spybot – Search & Destroy is one of the most used portable antispyware available on the Internet. You can scan the entire system or a particular file scan. Spyware is quarantined and you can get the scan statistics from there.

Spybot – Search & Destroy detects and removes tens of thousands of spyware and malware from the PC. You can also clean the traces coming from the use of software and registry correction. Spybot is freeware for personal use. Many cleaning and immunization features require administrator rights that will be required at startup.

3. Kaspersky TDSSCleaner

The Rootkits are one of the main problems in a computer system. Rootkits hide the existence of malware and anti-virus software does not recognize them during the scan. In this case, an anti-rootkit software is also necessary. Kaspersky TDSSKillerprovides security and prevents the rootkit from exploiting the system. It is possible to remove some of the common and known rootkits that could affect your computer system.
You just have to start the scan and the report will be generated. You can change the scan parameters in which system drivers and system memory can be filtered from the scan. In addition, you get additional options to verify the digital signature of each software.

4. HijackThis

HijackThis finds out if any malware has made any changes in the registry or in the system settings. A log file is created that displays which files have been modified. You can then further restore the values that have changed. Together with the software, you get a group of tools that include Uninstall Manager, Host file manager and Process manager.

5. FileAssassin

During the file deletion process, you may run into an alert such as “Access denied” or “I can delete the file“. This occurs when one of the malware has hit that file and does not allow you to delete it. In this case, FileASSASSIN can come to your aid. It will not only delete the file, it will also terminate the processes that have been affected by the malware. Just select the file and press Run.
If you wish to delete the file from the software itself, then you will have to select the option. Otherwise, the file will only be unlocked and you can delete it manually.

These are some of the best known free portable antiviruses for each category of virus. From these antiviruses on a USB stick, you can delete rootkits for malware that do not allow you to delete files. If you think that I have not reported an antivirus that is worthy of being included in this list, then let us know in the comments that we will insert it.
