Download antivirus flash drive. USB Disk Security – protects your computer from viruses from USB flash drives. Key Features of USB Disk Security

Get into operating system not via the Internet or email, but using a regular flash drive. Moreover, most often the owner of this removable media does not even know that his flash drive is infected with one or more viruses. But how to protect your devices from viruses? Is there an optimal antivirus for a flash drive or another reliable way to protect removable media? You will find answers to these questions in the continuation of this article.

First, let's define what exactly we are going to protect. After all, you can find a good antivirus for a flash drive that can prevent infection of your removable drive, but which cannot cope with more powerful threats that attack a computer or laptop. Therefore, you need to understand that your home PC should in any case be equipped with a good firewall and high-quality anti-virus software, which can provide reliable protection against any spyware and virus programs. Anti-virus should be written to a flash drive only if you use it quite often in public places (in libraries, universities, various computers may not be properly protected) and you are afraid that you might “infect” your portable device.

One of the best tools for protecting removable media is a free utility called Antirun. This program will not only help protect your computer from penetration of various harmful viruses, but will also protect your flash drive from getting various “network garbage” onto it.

Another popular program among advanced users for protecting removable drives is the USB Disk Security utility (at the time of writing this article, it latest version- 5.0.0.76). This software, occupying only one megabyte, is a compact analogue of a real full-fledged antivirus that can scan removable media and delete infected files from it.

Another option for protecting any removable media connected to a computer via a USB port (this can be not only a flash drive, but also a memory card from a digital camera or mobile phone, MP3 player and other equipment) - prohibit the ability to write any data to this medium without user confirmation for this action. This option will allow you to fully control what, where and when was recorded on your storage device in order to avoid recording it on it and then you will not need any antivirus for flash drives.

To protect your computer from possible threat on the removable media side, experienced users recommend updating anti-virus databases as often as possible and from time to time completely scanning all hard disks and removable media that you use regularly. An anti-virus for a flash drive should only be installed if a computer or laptop for some reason has been left for some time without reliable anti-virus protection. If this computer has access to the Internet, then it can be scanned for third-party and potentially dangerous programs even online - many leading antivirus manufacturers offer this service completely free of charge these days.

We should not forget that if you handle your computer and removable media carelessly and negligently, no antivirus for a flash drive or PC will help against malicious software. If you regularly check the operating system and its resources using specialized programs, the likelihood of your computer becoming infected is practically reduced to zero. The main thing is not to forget to comply with the simplest requirements for protecting your PC and you will not have to contact repair shops after any breakdowns associated with viruses and other malicious programs.

Every storage medium can become a haven for malware. As a result, you may lose valuable data and risk infecting your other devices. Therefore, it is better to get rid of all this as soon as possible. We will look further at how you can check and remove viruses from your drive.

Let's start by looking at the signs of viruses on a removable drive. The main ones are:

  • files appeared with the name "autorun";
  • files appeared with the extension ".tmp";
  • suspicious folders appeared, for example, "TEMP" or "RECYCLER";
  • The flash drive stopped opening;
  • the drive cannot be removed;
  • files have disappeared or turned into shortcuts.

In general, the media becomes slower to be detected by the computer, it takes longer for information to be copied onto it, and sometimes errors may occur. In most cases, it would be a good idea to check the computer to which the flash drive is connected.

To combat malware, it is best to use antivirus software. These can be either powerful combination products or simple, highly targeted utilities. We invite you to familiarize yourself with the best options.

If the antivirus installed on your computer does not detect anything suspicious, but the symptoms are obvious (freezes, incomprehensible running processes, appearing autorun.inf on flash drives, etc.), a “one-time antivirus” is necessary. It's easy to use - just download from the link and run it. In this case, during the scan, it is advisable to disable the antivirus that is installed on a permanent basis.

Advantages of disposable antiviruses

1. Free. For home use, almost all one-time antiviruses are free.

Flaws

1. They are not able to protect your computer all the time (there is no module for constant protection) and there is no update of anti-virus databases.

2. You have to download it again every time so that such an antivirus detects new viruses.

Dr.Web CureIt!

Dr.Web CureIt!- a good one-time antivirus. Knows how to fight running viruses (does not allow itself to be killed during scanning).

HerdProtect

This a good option, if unlimited Internet is connected.

Minus: does not know how to treat infected files.

Plus: You don’t need to download it again to check, the databases are always fresh.

Kaspersky Virus Removal Tool

ESET Online Scanner

Plus Online scanner - no need to worry about downloading new versions with fresh databases. Just open the link or run esetsmartinstaller_rus.exe, the antivirus will start, update and scan your computer for viruses.

Powerful antivirus utility(not a full-fledged antivirus!) for advanced users. There is not a sea of ​​functions, but a whole ocean.
