A program to protect the disk from viruses. We check and completely clean the USB flash drive from viruses. Using third-party programs

Fall into operating system not via the internet or email, and using a regular flash drive. Moreover, most often the owner of this removable medium does not even know that his flash drive is infected with one or more viruses. But how do you protect your devices from viruses? Is there an optimal antivirus for a flash drive or another reliable way protecting 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 the infection of your removable disk, but which cannot cope with more powerful threats that attack your computer or laptop. Therefore, you need to understand that a home PC in any case should be equipped with a good firewall and high-quality antivirus software, which can become reliable protection against any spyware and virus programs... Antivirus should be written to a USB flash drive only if you use it quite often in public places (in libraries, university various computers may not be adequately protected) and fear that you might "infect" your portable device.

One of the best designed to protect removable media is free utility called "Antirun". This program will not only help protect your computer from the penetration of various malicious viruses, but also save your flash drive from getting on it with various "network garbage".

Another popular program for protecting removable drives among advanced users is the USB Disk Security utility (at the time of this writing, its latest version - 5.0.0.76). This software, which occupies only one megabyte, is a compact analogue of a true 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 using a USB port (this can be not only a flash drive, but also a memory card of a digital camera or mobile phone, MP3-player and other equipment) - prohibit the possibility of recording any data on this medium without the user's confirmation of this action. This option will allow you to fully control what, where and when was recorded on your media in order to avoid being recorded on it, and then you will not need any antivirus for flash drives.

In order to protect your computer from a possible threat from removable media, experienced users recommend updating the anti-virus databases as often as possible and from time to time to completely scan everything. hard drives and removable media that you use regularly. Antivirus for a flash drive should be installed only if the computer or laptop, for some reason, remained without reliable antivirus protection for some time. If this computer has access to the Internet, then it can be scanned for the presence of third-party and potentially dangerous programs even online - this service is now offered by many leading antivirus vendors for free.

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

It often happens that with regular use of a flash drive or other portable drive, we put our computer at risk.
This is especially dangerous when connecting someone else's USB device, the contents of which we can only guess. Thus, the probability of infecting your PC with viruses is very high.

USB Disk Security (Russian version) - excellent software solutionwhich is capable of automatic mode check the flash drive for viruses immediately after connecting it to the computer. Occupied volume random access memory so small that you can use the utility on low-power PCs and laptops.

The program is fully compatible with most antiviruses, such as DrWeb, Kaspersky, Nod32, so no software failures or system conflicts will arise, and installation will take a few seconds, because the size of this software is small.

The main task of the USB Disk Security utility is to provide maximum online protection against most types of viruses and computer threats that are spread through USB drives, memory cards, portable hard drives and other external USB devices.

Now, you can check your computer for viruses online (by connecting a USB flash drive) without user intervention - everything happens in automatic mode.

Attention: USB Disk Security is not a full-fledged antivirus, but only complements its functions in relation to external drives and is activated when they are connected to the computer. In other words, to achieve reliable protection against hacking and system infection, you need to have a fully functional antivirus with up-to-date databases and support for the firewall (firewall) function. Only in this case, you can be sure of the relative protection of your computer from viruses and other potentially unwanted software.

A highlight in Russian can be called its ability to scan your computer for viruses online for free - the developers have created a special module that allows you to check suspicious sites for malware. In addition, the program allows you to adjust the list of startup applications and clean up memory from garbage. All of this adds up to the pluses of this great and free utility. You can download the program for free from the official website, or you can follow the link below (we have already done this for you).

All malicious files that intend to get into the user's computer will be isolated and cured of the virus.

Checking the flash drive for viruses is mandatory, but if it is inconvenient to do it manually, then we recommend installing YUSB Disk Security!

The most common reason for a PC infection is due to an outdated anti-virus database that has no information about new threats. USB DISK SECURITY has its own unique algorithm for detecting malicious code fragments, which allows you to quickly respond to security threats.

As well as cloud services we very often use regular flash cards to store photos and movies. We connect it to other people's computers and laptops, which carries the risk of infection with viruses and other malicious programs. The statistics are unforgiving: every 10th computer is a direct threat. The question arises: how to protect a USB flash drive from viruses without reducing the comfort of its use?

Windows standard methods

Most often, USB media is infected through a file autorun.inf... This file serves a very specific purpose: automatic start or installing applications from a flash card to a computer. It is hidden, but it is present on any flash drive. As in other areas of life, early protection and prevention is better than laborious treatment, which does not guarantee 100% positive results. Therefore, the main task is to make the autorun.inf file invulnerable to attempts to infect it.

Extremely important: the methods described below will protect the media from malware that uses USB-flash as a means of distributing itself (it is they who tend to overwrite the mentioned file in their own way). Viruses, trojans and other troubles in program installers will not go anywhere: use antivirus software to detect them.

Disable startup

This is a method of protecting the computer itself from a possibly already infected flash drive, both from yours and from someone else's. The easiest way to do this is to follow the steps below. For Windows 7:

• Press key combination Win + R.
• In the "Run" window that opens, enter gpedit.msc and click on OK.

• Click on "Allow" when a message appears about the need to perform an action on behalf of the administrator. You may also need to enter an administrator password.
• In the local editor window that appears group policy expand the list "Computer Configuration" and then "Administrative Templates".
• Select the item "All parameters".

• In the opened list on the right right click mouse click on the line "Disable autorun".

• Press "Change", make the item "Enable" active, the value "All devices" should be set below.

• Click "Apply".

Please note: some windows versions (8,8.1) the sequence in steps 4-6 may differ slightly and look like this: "Computer Configuration" - "Administrative Templates" - " Windows components"-" Autorun policies "-" Disable autorun ".

A reboot may be required for the changes to take effect. That's all - now any flash drives connected to the computer will not start automatically on it and will not cause harm without the user's participation.

Autorun file protection

Now there is a way to defend the flash drive itself from malware that spreads using physical media. This is the very autorun.inf.

In the old days it was enough to create an empty write-protected file on a USB-drive. That is, with read-only rights. Today, such measures are not enough. But the essence of the actions is similar. On a USB stick, verified good antivirusafter making sure there are no dangers, create a special file. Open a regular notepad and copy these lines into it:

attrib -S -H -R -A autorun. *
del autorun. *
attrib -S -H -R -A recycler
rd "\\\\? \\% ~ d0 \\ recycler \\" / s / q
attrib -S -H -R -A recycled
rd "\\\\? \\% ~ d0 \\ recycled \\" / s / q
mkdir "\\\\? \\% ~ d0 \\ AUTORUN.INF \\ LPT3"
attrib + S + H + R + A% ~ d0 \\ AUTORUN.INF / s / d
mkdir "\\\\? \\% ~ d0 \\ RECYCLED \\ LPT3"
attrib + S + H + R + A% ~ d0 \\ RECYCLED / s / d
mkdir "\\\\? \\% ~ d0 \\ RECYCLER \\ LPT3"
attrib + S + H + R + A% ~ d0 \\ RECYCLER / s / dattrib -s -h -r autorun. *
del autorun. *
mkdir% ~ d0AUTORUN.INF
mkdir "?% ~ d0AUTORUN.INF ..."
attrib + s + h% ~ d0AUTORUN.INF

Save the result to a USB flash drive by naming the file locker.bat... After the dot there is an extension, it is extremely important and should look exactly like .bat... Open the USB flash drive through the explorer and run the newly created file with the usual double click of the mouse. It will execute as a small program and create a protected AUTORUN.INF folder.

What does it do? By inserting a USB Flash Drive into an infected computer, there is no need to be afraid of the viruses on it that spread via USB. Such a virus will rush to overwrite the autorun.inf file, but it does not exist! Instead, a folder, and even protected.

It is also important: viruses can write themselves to other places on the USB flash drive by changing other files. Therefore, when inserting it into a computer, check it with an antivirus before opening it.

Radical way

If you have to connect a USB flash drive to someone else's computer, but only to drop files from it, the option of switching the file system to read-only mode is suitable. This is an effective, but, in most cases, inconvenient way of making the “send to removable drive»And similar operations.

In order to apply this method, you must:

• Format USB drive to file nTFS system. Please note: all data from the flash drive will be deleted!If your flash drive is already in NTFS, skip this step.

• Write down all the necessary data, put them in one folder.
• Open the properties of the flash drive (right-click) and in the "Security" tab click on the "Change" button.

• In the "Allow" column, uncheck all the boxes except for the items "List of folder contents" and "Read".
  Click "OK".

Now no virus will be able to register on the USB stick.

Using third-party programs

You can also protect USB media from malware using specially created programs. For example, Panda USB Vaccine. This free utility is designed specifically to protect removable media.

After downloading and running it, connect the USB flash drive that you want to protect to the computer. Follow 2 easy steps:

1. In the drop-down menu, install the required USB-drive;
2. Click on the Vaccinate USB button.

And that's it! The flash drive is protected from overwriting the autorun file. In fact, the program simply disables autorun, but it does so by pressing a couple of buttons in a user-friendly interface.

Output

Unfortunately, you cannot 100% protect your flash drive from viruses. The measures described in the article only prevent the automatic penetration of malware first onto a USB drive, and then onto your PC. Always keep your antivirus up to date and scan your flash drives before opening them in File Explorer.

Good day! Today's article will discuss how to check a USB flash drive for viruses. I think this issue is currently the most relevant. It is possible to pick up viruses on your computer not only through the Internet, but also through a flash drive.

Today, not using antivirus while browsing the Internet is akin to suicide. Nevertheless, there are individuals who disregard this golden rule and catch clouds of different infections on their computers. Very often, an antivirus scan without installing it in the operating room allows to save the situation. windows system... Moreover, after infection, malware very often does not allow anything to be installed. Today I will tell you about several antivirus scanners that work in portable mode. Such a utility can be downloaded to a USB flash drive and run on an infected system. In 80% of cases, this helps to regain control of the computer in their own hands in order to at least have time to save important data.

The best antivirus without installation - TOP3

1. DrWeb CureIT
I have been using this antivirus scanner since its inception and therefore it is my number one! And how many times he helped me out at work - I can't even count! Dr.Web CureIt! By far the most popular so-called online antivirus that is constantly updated and has no conflicts with other antivirus software, if one is already installed on the PC. You can download it here - link.
After launch, the application will require you to accept the terms license agreement... And then you will see this window:

Press the "Start check" button and the utility will carry out all the necessary checks of the RAM, running processes and system folders, after which it will give out a list of what was discovered and suggestions for further treatment of the OS.

2. Kaspersky Virus Removal Tool - KVRT
This antivirus was released without installation, the main competitor of the previous program. The program was released by the world's most famous anti-virus laboratory, Kaspersky.

The KVRT algorithm of actions is similar to DrWeb CureIT. Download the application here - link. Then we launch, accept the license and press the "Start check" button. After checking, we agree with the proposed course of action and wait until the found infection is destroyed! Upon completion of the work, you will receive a report from the program on the work done!

3. ESET Online Scanner
At the moment, the ESET Online Scanner is the only full-fledged online antivirus that uses cloud technologies... I think it is clear that to check your PC and remove viruses from it, you need to have active connection to the Internet.

The utility pleased with its size - just over 6 megabytes against 140-150 in the previous two cases. Easy to download here - link, easy to work! It detects more quantities of modern virus infection! Although I often hear complaints from users about its work. I use it infrequently and in the case when I need a quick scan for viruses without installing an antivirus, and there is no time to download the previous two solutions, or the system scan with their help did not give any results. You can download ESET's online antivirus for free here - link.

Other portable antiviruses (Portable)

In general, now Portable-antiviruses are few in number, I have named the best of them above, and below I will list several alternative options, rather even for familiarization. Using them, as a rule, does not give significant results (well, with the exception of Komodo, perhaps), although sometimes these portable utilities even find something and treat it.

Comodo Cleaning Essentials (Free Malware Removal Tool)

This is not just an online antivirus, but a whole set of special utilities, including a portable scanner, autorun and process analyzers, and a Hijack Cleaner spyware and adware detector. In principle, I can't say anything particularly bad about Komodo. I used their programs quite a lot and often. Now I use it only when there are no normal alternatives at hand.

Another online antivirus from F-secure, using their proprietary Lighthouse technology. It is protected by Facebook - probably it speaks to some of its benefits. As for me - beautiful on the outside and weak on the inside. There are a lot of mistakes in work and complaints from disgruntled users.

I have a negative attitude to software products from Norton ever since when I had to delete them in batches on client laptops. This heavy, clumsy monster slowed down the system and almost did not even find known viruses... How their vaunted Symantec heuristic works is a mystery to me. I frankly dislike their products and antivirus scanner without Norton Power Eraser is no exception. He is very annoyed by his aggressive interference with the computer. Well, he would only be looking for viruses, so this infection also climbs to fix the registry. And after such fixes, you can get a non-working Windows. So if you decide to use it, be sure to check the box for creating backup registry!
And yes, it often works on normal regular programs. This can be seen in the screenshot.

Microsoft has never seriously dealt with antivirus software, and circumstances forced them to take this path. Their portable antivirus is even more weight than counterparts from Doctor Web or Kaspersky. The application works not to say that it is fast - verification takes a lot of time. Sometimes he even finds something. If you surf the Internet, there are few positive reviews about Microsoft Safety Scanner.
