If the main information is stored on the computer’s hard drive, you need to protect your data from hacker attacks. Recently, there have been more frequent cases of using agent programs that transmit to their owner all typed texts, including passwords and bank account details.
You will need
- - a computer with antivirus software installed on it,
- - Special anti-spyware utilities.
1. In order to check your computer for the presence of spyware, go online and download a special utility. There are a lot of similar software on the Internet, however, you should heed the judgment of other users and find out the reputation of the manufacturer of the program. Unfortunately, there are cases when, under the guise of a special utility, a user voluntarily downloaded to his computer just the programspy . Fortunately, there are some signs that suggest that the computer has snags that need to be addressed urgently.
2. Launch a browser, a program that is commonly used to access the Internet. Check out the download page. If an unknown page loads, which, moreover, still cannot be changed, this is a good sign that a high-tech virus has settled on the computer. Usually he changes the user's main page to the page of the site, from which more and more new shares of viral troubles are strewn onto the computer.
3. Monitor the behavior of the computer operating system. If it periodically freezes or even crashes, then you need to check the boot files and the activity of unfamiliar processes in startup
4. Ask your provider or find out for yourself if a steep increase in Internet traffic is being monitored. The presence of such a jump indicates the source’s work, one that is unknown, but at the same time receives and transmits a significant amount of data.
5. Open the task manager, go to the "processes" tab. Here, with a probability of 80%, it is allowed to find the effect of third-party programs. However, only an expert or an experienced user will be able to do this. Particularly unpleasant spyware masquerades as system processes, that is, they look quite peaceful. Moreover, the computer often refuses to delete malicious files, mistaking them for service or system ones.
Tip 2: How to Detect a Spy on a Computer
While working on the Internet, a malicious program can penetrate your computer. These include viruses and spies. They can be perfectly different. Many spies monitor your keyboard. In order to discover spy on computer , Before each, you must install the appropriate software. To date, there are a huge number of such utilities on the Internet.
You will need
- Personal computer, Anti-Agent program
Tip 3: How to Calculate a Spy
Spies can be not only in films. No matter how unusual, you can meet them in your office. An agent can work with you side by side, and you don’t even suspect anything. It may turn out to be a harmless neighbor, the one sitting opposite you, or the girl who got a job for you shortly. But how do you recognize them?
Tip 4: How to Find a Keylogger
Keyloggers or keyloggers (from the English keylogger - keystroke logger) have been around for more than 10 years. For all this time, spyware programs have been made that are able to transfer logins and passwords from user accounts of the Internet. In some cases, people have lost millions of bucks by trusting suspicious sources and emails with a rather unusual table of contents.
You will need
- Antivirus software with continuously updated signature databases.
Tip 5: How to Find a Spyware
New viruses and trojans are created every day. Even if an anti-virus program with regularly updated databases is installed on the computer, this does not guarantee complete protection against harmful software. In many cases, the user has to check the computer for spyware.
Tip 6: How to run the program on a remote computer
Occasionally, a computer user is required to gain access to a computer that he is not currently using. The reason for this may be the acquisition of data from a working computer to your home or vice versa in order to complete the work.
You will need
- - computer,
- - the Internet,
- - software.
Tip 7: how to declassify a spy
As long as there are states, there will also be spies, that is, people who extract classified data on the territory of one country for transmission to the competent authorities of another country. Accordingly, every sovereign state considers espionage as a direct threat to its national interests, and is constantly engaged in the detection of agents.
What is a spyware program?
To begin with, spyware applications, or executable applets, usually called Spyware (spy in English “spy”), in the usual sense, are not viruses as such. That is, they have virtually no effect on the system in terms of its integrity or performance, although when infected computers are able to constantly reside in RAM and consume part of the system resources. But, as a rule, this does not particularly affect the speed of the OS.
But their main purpose is to monitor the user's work, and if possible - steal confidential data, replace email with the aim of sending spam, analyze requests on the Internet and redirect to sites containing malware, analyze information on the hard drive, etc. It goes without saying that any user must have at least a primitive antivirus package installed for protection. However, for the most part, neither free antiviruses, nor even the built-in Windows firewall give complete confidence in security. Some applications may simply not be recognized. This is where the quite natural question arises: “What then should be the protection of the computer against spyware?” Let's try to consider the main aspects and concepts.
Types of Spyware
Before embarking on a practical solution, you should clearly understand which applications and applets belong to the Spyware class. Today, there are several main types:
- key loggers,
- hard drive scanners
- screen spies,
- mail spies
- proxy spies.
Each such program has a different effect on the system, so let's see how spyware programs penetrate the computer and what they can do in the infected system.
Spyware Penetration Methods for Computer Systems
Today, in connection with the incredible development of Internet technologies, the World Wide Web is the main open and insecure channel that threats of this type are used to integrate into local computer systems or networks.
In some cases, the user installs spyware on the computer, however paradoxical this sounds. In most cases, he does not even know about it. And everything is simple. For example, you downloaded a seemingly interesting program from the Internet and started the installation. In the first stages, everything looks as usual. But then sometimes windows appear suggesting the installation of some additional software product or add-on to the Internet browser. Usually all this is written in small print. The user, trying to quickly complete the installation process and start working with a new application, often does not pay attention to it, agrees with all the conditions and ... as a result, gets an embedded "agent" to collect information.
Sometimes spyware programs are installed on a computer in the background, disguised later on important system processes. There may be plenty of options here: installing unverified software, downloading content from the Internet, opening dubious email attachments, and even simply visiting some insecure resources on the Web. As already clear, it is simply impossible to track such an installation without special protection.
Effects of exposure
As for the harm caused by spies, as already mentioned, on the system this is generally not reflected in any way, but user information and personal data are at risk.
The most dangerous of all applications of this type are the so-called key loggers, or more simply, keyloggers. Just they are able to monitor the character set, which gives the attacker the opportunity to obtain the same usernames and passwords, bank details or PIN codes of cards, and all that the user would not want to make available to a wide range of people. As a rule, after all the data has been determined, they are sent either to a remote server or by e-mail, of course, in stealth mode. Therefore, it is recommended to use special encryption utilities to store such important information. In addition, it is advisable to save the files not on the hard drive (they will easily be found by hard drive scanners), but on removable media, and at least on a flash drive, moreover, it must be with the decryptor key.
Among other things, many experts consider the most secure use of the on-screen keyboard, although they recognize the inconvenience of this method.
Tracking the screen in terms of what the user does is dangerous only when confidential data or registration details are entered. A spy simply takes screenshots after a certain time and sends them to an attacker. Using the on-screen keyboard, as in the first case, will not give a result. And if two spies work at the same time, then you can’t hide anywhere at all.
Email tracking is done by contact list. The main goal is to replace the contents of the letter when sending it with the aim of sending spam.
Proxy spies do harm only in the sense that they turn the local computer terminal into a kind of proxy server. Why is this needed? Yes, only to hide behind, say, the user's IP address when committing illegal actions. Naturally, the user is unaware of this. So, let's say someone hacked into a bank’s security system and stole a certain amount of money. Tracking the actions by authorized services reveals that the hacking was carried out from the terminal with such IP located at such address. Special services come to an unsuspecting person and put him in jail. True, there is nothing good in this?
First symptoms of infection
Now let's move on to practice. How to check the computer for spyware, if suddenly for some reason doubts crept in the integrity of the security system? To do this, you need to know how the effects of such applications are manifested in the early stages.
If for no apparent reason a slowdown is noticed, or the system periodically “hangs”, or even refuses to work, for a start you should look at the load on the processor and RAM, and also monitor all active processes.
In most cases, the user in the same “Task Manager” will see unfamiliar services, which previously were not in the process tree. This is only the first bell. The creators of spyware are far from stupid, so they create programs that disguise themselves as system processes, and it is simply impossible to identify them without special knowledge in manual mode. Then the problems with connecting to the Internet begin, the start page changes, etc.
How to check your computer for spyware
As for the verification, full-time antiviruses will not help here, especially if they have already missed the threat. At least some portable version like Dr. Web Cure It! or Kaspersky Virus Removal Tool (or better, something like Rescue Disc with a system check before it boots).
How to find spyware on a computer? In most cases, it is recommended to use highly targeted special programs of the Anti-Spyware class (SpywareBlaster, AVZ, XoftSpySE Anti-Spyware, Microsoft Antispyware, etc.). The scanning process in them is fully automated, as well as subsequent deletion. But there are things worth paying attention to.
How to remove spyware from your computer: standard methods and third-party software used
You can even remove spyware from your computer manually, but only if the program is not masked.
To do this, you can go to the programs and components section, find the application in the list and start the uninstallation process. True, the Windows uninstaller, to put it mildly, is not entirely good, because it leaves a lot of computer garbage after the process is completed, so it’s better to use specialized utilities like iObit Uninstaller, which, in addition to deleting in the standard way, allow you to perform in-depth scans for searching for residual files or even keys and registry entries.
Now a few words about the acclaimed Spyhunter utility. Many call it almost a panacea for all ills. Let us disagree with this. She scans the system for nothing, though sometimes it gives a false positive. The problem is not this. The fact is that uninstalling it is quite problematic. The average user of all the number of actions that need to be performed, just a head spin.
What to use? You can protect against such threats and search for spyware on your computer, for example, even using the ESETNOD32 package or Smart Security with the Anti-Theft function activated. However, everyone chooses what is better and easier for him.
Legal Spying on Windows 10
But that's not all. All of the above applies only to how spyware penetrates the system, how it behaves, etc. But what to do when espionage is legal?
Windows 10 in this regard has distinguished itself not for the better. There is a bunch of services that you need to disable (data exchange with remote Microsoft servers, using identification to receive advertisements, sending data to a company, determining location using telemetry, receiving updates from several places, etc.).
Is there 100 percent protection?
If you look carefully at how spyware penetrates the computer and what they do afterwards, you can say only one thing about 100 percent protection: it does not exist. Even with the use of the entire arsenal of funds in safety, you can be sure of 80 percent, no more. However, from the side of the user himself, there should be no provocative actions in the form of visiting dubious sites, installing unsafe software, ignoring antivirus warnings, opening email attachments from unknown sources, etc.
