When we use our computer on the internet, we are allowing it to potentially be infested by one of the many dangers that float around on the World Wide Web. So to try and prevent that, we set up programs on our system that are supposed to seek out and stop dangers such as this. But even the latest updated antivirus will not be able to stop every danger that may be out there. This is why it is a good thing for you to know which part of your Window 7 system is a place where an infection or potential infection is most likely to hide. This way if anything strange happens to your computer and you are at a lost as to what is going on, you can check these areas to see if they are clean or not.
The first folder that you want to take a look at in your Windows 7 system is the “Downloads” folder of the computer. If you have downloaded anything to the system, then you know that by default it ends up here. So there is a good chance that anything that may be harming your system originated from this folder. Luckily for you, if the file is still in this folder and you have not accessed it beforehand, then there is a good chance that the infection can be easily removed. Programs usually have to have some sort of interaction to be installed. The method that this occurs is usually by double clicking on an .exe file. On rare occasions, a program can activate without any interaction at all. If the program in this folder is doing that, then deleting the .exe in the folder should get rid of all of your problems.
Another folder that infections like to hide in is the “Programs Files” folder. Whenever you install a new program, the .exe and other files by default are put in this folder. Many virus and other malware writers will rarely put their infections in this folder but some do and that makes it a good place to look. Or if they do put the files and .exe in this folder, then they will place it under a different name. So if you see anything in this folder that seems off and your computer is acting funny, then go online and Google some of the folders that you do not recognize. They may be your problem.
The last folder that you should check is the actual Windows folder. This is where the heart of your operating system is at. You should only access this folder if you know what you are doing. If you have never been in this folder before, then do not go in it now. Only go in if you are familiar with the files that are in this folder. If you are familiar and you see a strange name that you haven’t seen before, then it is again time to check Google.
Even if you know where to look at, you are still going to need a program that will able to analyze the files in the folders to see whether they are good or not. To do this, you can use an online virus scanner to help you out. Viruses can be tricky things; it helps to know where they may be hiding at.
When we use a firewall on our computer, it gives us the ability to effectively become a bouncer with our system. We have the power to selectively decide who is able to get in to or out our system through the internet. If there is a program that is installed but we do not expect it to try and access the internet, we can prevent it from doing that. We have to be smart when we decide which program should have access to the outside network and which ones shouldn’t. There are a couple of factors that will help you decide which programs should be granted permission to do this. In this article we will show you how you can decide which ones you should let have access to the internet and which ones you should not. By the end of this article, anytime that you download a new program, you will be able to see very clearly if it should be allowed this type of access or not.
The first way that will help you decide if the program should be able to access the internet or not is your familiarity with the program. This means that trust is the number one factor that will play into your decision. If the program is something that you have used for awhile now or it is made by a company that you absolutely trust, then you will most likely be comfortable in letting it access the outside internet. It is the programs that are new to you that you will have more problems in trusting. But even if you trust the company, before you let the program access the internet, you should still check to see why it wants to have this ability. There are plenty of companies that started off trustworthy but turned into a nightmare for its users.
Another big factor in whether you should allow the program to use the internet is if that is what you downloaded the program to do. In other words, if the program was downloaded to be used as a text editor only, then there is no reason why it should need the internet. The only reason why it would want to access it is so that it is allowed to send usage data about you and the program. That is not a bad thing in of itself but it also not a reason why a program should be granted such access. So when you download and install a program to your computer, make sure that you know what it does first. That will help you decide if it needs to be on the internet or not.
Allowing a program to have access past your firewalls is a very important thing. If you allow the wrong program to have this privilege then you can be setting up yourself up for disaster. This is why you should know as much about the program as possible before making such a decision. If you do not then you can end up paying the price later on down the line.
As you can probably tell from the title, keyloggers are very dangerous programs. But they are programs that you do not hear about every day. They do not get the same press as a computer virus does. If you are involved in computer security then you should be very familiar with them. To the public at large, they really are still a mystery. The one thing that the public should know about them is that if they are ever able to get into your computer, then your privacy on your computer could be severely compromised. There is nothing that you would be able to do on your computer without the bad guys knowing about it. So let’s talk about keyloggers and how they are able to be this destructive.
What keylogger do?
A keylogger is a program that sits on your computer in the background and registers the keystrokes that you make. It then reports the information back to the main server that controls it. There are hardware versions of this type of program as well but these days you will mostly see the software variety. Whenever you type a letter on your keyboard, you are sending a signal that gets registered to your operating system. The operating system, after it translates it, then sends the signal back to the hardware so that the letter that you typed shows up on the screen. So when the keylogger is sitting in the background during this time, it is taking notes of everything that is being pushed. Once the notes are taken, after a certain amount of time, it then sends it back for the person controlling the server to shift through. Once they see this information, they can use it for their own personal gains. This means that they can either sell it to scammers, or try to scam you themselves.
If you want to make sure that your system steers clear of keylogger, then there are a couple of things that you must do. The first thing that you must do is to make sure that you have an updated antivirus on your system the whole time. A keylogger is usually introduced onto your computer by a Trojan. A Trojan is a piece of malware that carries another piece of malware and delivers it to the target system. Luckily for you, an updated antivirus program will be able to catch a Trojan as well. So as long as you have that on your system then it will help keep you secured. You also want to make sure that you stay off of dangerous web sites. Questionable web sites might be able to have you catch something like this as well. Also, make sure that the links that you click are trusted and will not lead you to any bad places.
As you see there is a lot of dangers that can be picked up on the internet, even some that you have never heard of before. If you want to make sure that your system stays safe, then you need to keep aware of danger such as a keylogger. You do not want anything like this being able to sneak through onto your system.
