Who is using clamav

Log in or Sign up. Suggested articles. By: BetterMJ at: By: till at: Use "--help" and not "-help": clamscan --help. By: Frits at: Nice artikel. Please do realize that Clamav does not scan compressed files like. You can use avg for linux, use avgscan -a. By: Sammy at: Just created a bash to save and run every so often, this takes a while to run. By: Keith R. Starkey at: Thanks very much!

By: Saad at: By: Rich at: I came to the comments to say the same thing. By: Graham at: Thanks for sharing this, just what I was looking for.

By: gsjdbf at: Instead of a manual scan, how can i set up clam av to scan a certain folder everyday? Create a cronjob that runs the clamscan command daily.

By: John Sowden at: The got 0 was consistant. For manual use: install the package clamav. For automated use: install the package clamav-daemon. Both methods will also install the updater clamav-freshclam. If one wants a GUI, then install the package clamtk. You will see an output like this: sudo freshclam ClamAV update process started at Wed Apr 27 main.

If you want to check all files on the system, use the sudo command see UsingSudo for more information. This can be problematic. For example, if using Wine and it deletes an infected file, it could break a program without having the data saved.

However, ClamWin does not provide on-access scanning and needs additional software to do that. It runs in the system tray and can detect any file system changes. It scans the modified files using ClamWin in real-time. It also features optional system change messages and proactive heuristic protection.

Heuristic analysis is used by many antivirus software to detect unknown viruses using various decision rules and weighing methods.

ClamAV, too, uses this type of protection. Types of malware Malware is a computer program or software that contains a bug created intentionally or because of bad coding , which can cause harm or access to a computer system or data, without the consent of the user. Various types of malware include computer viruses, worms, Trojan horses, ransomware, spyware, adware, rogue software, wiper and scareware. Among these malware, computer viruses and Trojan horses are most commonly used to harm a computer, and are spread through Internet files and computer games.

The techniques used by antivirus or anti-malware software Malware may be of various types and could give many kinds of problems. To get rid of any such malware, we need powerful antivirus software.

An antivirus or anti-malware is software that is capable of preventing and detecting a malware, but may not always be able to remove it. It was first developed to detect only computer viruses because these were the more common types of malware attacks initially.

But nowadays, such antivirus software is also capable of dealing with many kinds of malware; so now such software can also be termed as anti-malware. Reaper was the first antivirus program created by Ray Tomlinson in and was capable of deleting the Creeper virus.

Antivirus software works mainly using signature and behavioural based techniques. In signature based detection, when any new malware is discovered by researchers, its file signature is extracted and added to the database of the antivirus.

In behavioural detection, the algorithm or the intention of a malicious program is understood and all suspicious behaviour is added to the database of the antivirus. During the execution of a file, the antivirus monitors the executed program and tries to find behaviour that matches with the database.

Besides these two techniques, other methods like sandbox detection, data mining techniques, heuristic analysis, rootkit detection and real-time protection are also used.

Sandboxing uses a virtual environment to run the suspected program and isolate it from the real environment. It then checks the behaviour of the program and compares it with the database; if any match is found, it is flagged as malware.

This method is safe and protects the system from any malware attack. The data mining technique uses machine learning algorithms to classify malware based on its behaviour. Heuristic analysis is a technique used to identify the genre of a virus or malware.

Usually, attackers can create variants of a virus and there can be a family of similar viruses, forming a genre. It is easier to identify the signature of the genre than to detect a specific virus.

Heuristic analysis creates the signature genre of various families of viruses based on their behaviour, which is stored in the database of the antivirus. When the behaviour of a program matches the genre of a virus, it is flagged as a virus belonging to that family.

Rootkit detection is used particularly for malware called rootkit, which can take administrative control over the computer.
