Enter the 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 protection of 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, it is necessary to understand that in any case, your home PC should be equipped with a good firewall and high-quality anti-virus software, which can become reliable protection against any spyware and virus programs. Antivirus should be written to a flash drive only if you use it quite often in public places (libraries, university various computers may not be properly protected) and are concerned that you may “infect” your portable device.

One of the best solutions for protecting removable media is free utility called "Antirun". This program will not only help protect your computer from the penetration of various malicious viruses, but will also protect your flash drive from various “network junk” getting 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 from removable media, experienced users recommend updating anti-virus databases as often as possible and completely scanning everything from time to time hard drives 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.

When your computer is infected with viruses to such an extent that operating system it doesn’t even start anymore, there is only one way out - SCAN IT WHEN LOADING.

That is, we need to scan it, even before the operating system boots, to find all malicious programs and remove them. Then reboot our PC and again enjoy its working state.

The fact is that when I first encountered a problem when the computer was infected with a virus and the operating system refused to start, I was simply horrified. Usually, if there is a virus on your computer, you simply find it using an antivirus program and remove it. And then the system did not boot at all. Simply, after turning on the computer, a window appeared asking how to send an SMS as usual, enter a code, and so on. In short another DIVORCE FOR MONEY!

What did I decide to do right away? I immediately came to the conclusion that it was necessary. I did this and was horrified when the virus again prevented the system from starting. How so? What to do if REINSTALLING THE SYSTEM DID NOT HELP?

Salvation can be scanning your computer for viruses when loading it! It’s great that I remembered about this, but I had never used it before.

We need to burn an image of an antivirus program to a disk or flash drive. Such images can be found on the official websites of antivirus developers such as Kaspersky, Doctor Web, and so on.

In this lesson I will tell you how to take an image of Kaspersky antivirus, write it to a USB flash drive and scan all disks on your computer, removing all viruses.

So now we'll start creating bootable flash drive with antivirus.

For this we need:

1. Formatted USB flash drive.

2. Kaspersky antivirus image

3. A program for writing an image to a flash drive.

I hope you already have a flash drive, all you have to do is download the necessary programs.

First, let's look at the program. Double-click on the downloaded file with the left mouse button.

Then in the window that opens, specify the folder to unpack the program, or leave it as default, then it will be unpacked in the same place where it is. Click the "Install" button

After unpacking, the program will automatically start. Click the “Browse” button.

We indicate on the computer where it is ISO image Kaspersky.

After the path to the image is specified, you need select USB drive, onto which Kaspersky anti-virus will be recorded, and click the “Start” button.

Our flash drive must be formatted for file system FAT or FAT32. Therefore, if we previously formatted it in NTFS, a window will appear where we must confirm formatting in FAT32. Click “Yes”.

The recording has started. We are waiting for completion.

After the bootable USB flash drive with the antivirus is created, a window with the text will appear: Kaspersky Rescue Disk was successfully written. Click "OK".

Now we need to prepare the computer for booting fromUSB storage device. You need to go into the BIOS and set it to boot from a flash drive. I'll show you using my BIOS as an example. It may be different for you, but the process will be similar, anyway!

We reboot the computer, do not remove the flash drive with the recorded antivirus from the computer.

When rebooting the PC, we need to go into the BIOS; to do this, press the DELETE or F2 key on the keyboard; it depends on your motherboard.

After entering the BIOS, find the Boot tab, select the item Hard Disk Drivers.

We put USB first.

We save the settings made using the F10 key and exit.

Now our computer boots from a flash drive.

If we did everything correctly, then Kaspersky will launch in a few seconds. Here we are asked to press the “Enter” key. Let's press.

Then, using the arrows on the keyboard, select the language “Russian”.

Accept the terms of the license agreement by pressing the 1 key.

Choose Graphics mode.

We are waiting for the program to start.

The program starts to scan your computer for viruses. We indicate by checkboxes which drives need to be checked and click “ Perform object check».

Disk scanning has started.

If any threats are detected in the process, we will need to take action. For example, “Delete” if the risk of infection is high, or “Skip” if it is not dangerous at all.

After all threats are found and removed, all we have to do is restart the computer.

And most importantly, reboot from hard drive, and check the functionality of the system.

This completes the lesson on creating a bootable USB flash drive with antivirus.

USB Disk Security- This free application to ensure complete protection against all kinds of malware, distributed via removable USB media. The application works with external hard drives, memory cards, digital cameras, flash drives, as well as other devices that can be connected via a USB connector. Disk Security is based on special threat detection technology; Like an antivirus program, the utility is able to work in hidden mode, only making its existence known only if malware is detected.

Basically, a personal computer is infected with viruses while using the global Internet; a little less often this happens during the installation of a dubious or unverified program. An infected file can also enter a PC through the most ordinary flash drive.

When connecting an infected flash drive to a personal computer, the malicious software penetrates hard drive, and most importantly, this happens so quickly that installed anti-virus programs do not always have time to react in time. Especially for such cases, it is necessary to use programs that can easily cope with this type of threat. Today Disk Security is one of the best programs to protect against infected files distributed via USB drives.

When viruses are detected, the application, depending on the settings, will delete or block them, thereby preventing them from launching automatically.

In addition to tools for automatically checking flash media, the “Scanning” section is equipped with a vaccination function. Vaccination can be carried out both on removable media and on the actual personal computer. In this case, a special file is created on a flash drive or hard drive that prevents some malicious applications from launching. If desired, vaccination can be turned off.

The “Data Protection” section is able to provide devices with higher protection; for example, you can set a ban on moving data from the computer to a memory card or even block access to the PC through USB port. To close access, you will need to restart the computer, only after this the settings will take effect.
