5 Important things you need to know about antivirus programs to protect your computer from any viruses and malware. Many of us use computers but many times our computers become slow due to viruses. It leaves us with a lot of worries. That is why we are looking for a solution. But our only repairman can’t find a way. That’s why we have a writer who will benefit you a lot.
Antivirus is part of the multilayer security strategy. Even if you are a skilled smart Windows computer user, you still need to use antivirus programs. Let’s find out how the antivirus program detects malware.
Testing the antivirus program:
What if you want to check that your antivirus is working properly? EICAR is a standard method of testing antivirus work. Even if it is a virus file, it will not harm you. If it detects your antivirus as malware then you need to know that the antivirus is working properly.
We continue to use a huge amount of software. Antivirus can mistakenly identify one of these secure files as malware. This is known as a False Positive. In some cases, the antivirus manufacturer remains at fault. As a result, the program infects various files of Windows system files, popular third party programs, or antivirus programs. There are also reports of this happening. Microsoft Security Essentials identified Google Chrome as a virus. AVG antivirus damaged 64 bit of Windows 8. The antivirus Sophos also identified itself as malware. Even then, if your antivirus calls a file a virus, you have to believe it. If you are not sure, you can upload the file to VirusTotal. The virus will scan the total file with various antivirus programs and tell you why your antivirus is calling it malware.
Definition files contain traces of viruses or malware that have already been encountered in the lab. When the antivirus program scans the files, it identifies them with known malware and sends them to “quarantine” to stop their execution on the system. Depending on the settings of the antivirus program, it may delete the infected file or allow you to run the file. If you think this is a wrong signal. Antivirus program makers regularly release virus definition updates. In antivirus labs, malware is divided into different tools, run in the sandbox, and updates are released over time. Companies try to protect the user from the attack of new malware.
Detection rate refers to the ability to detect a virus. Different antivirus programs have different detection rates. Some antivirus manufacturers increase the detection rate by releasing more virus definitions than their competitors. There are some organizations that regularly compare detection rates for antivirus programs.
AV-Comparatives (www.av-comparatives.org/comparativesreviews/dynamic-tests) is one such organization.
Complete system scan:
Real-time protection usually does not scan the entire system. You need to use the Full System Scans option to scan the entire system. If you download a virus to your computer, the antivirus will understand it in a moment. Can’t wait for your scan. However Full System Scans are required in some cases. When you install a new antivirus on your computer, you need to scan the entire system. So you can be sure that there is a virus hidden in your computer while it is dormant?
Antivirus software runs in the background on your computer and checks all files when opened. This subject is known by different names. For example – on-access scanning, background scanning, resident scanning, real-time protection, and other things that will depend on your antivirus program. When you open an EXE file by double-clicking on it, it seems to open quickly. In fact, it is not. Your antivirus program first compares the file with all other types of malware and other types of malware, then considers the various pros and cons of the program, and then runs the program. The antivirus program also scans other types of files containing viruses. For example, a zip file may contain a virus in a compressed state. Or the word document may contain malicious macros. The antivirus scans the file when the file is used. When you download an EXE, the file is quickly scanned before it is opened.
I hope you have some basic ideas about antivirus.
