All computer users must have experienced the hassle of dealing with viruses that attack their computers. If the computer is exposed to a virus then its performance becomes slow so that it cannot be compromised for optimal use.
Viruses can be broadly interpreted as any program or software that is able to interfere with our computers so that they cannot do their work normally and generally these ugly viruses are detrimental to the computer being attacked.
Therefore, many want to know the lightest anti-virus, so as not to be hampered in their daily work just because of a computer virus.
Why Called Virus
Anti virus is the lightest or the heaviest is very important owned by every computer, whether in the form of portable, notebook, or netbook.
Anti-virus must be able to anticipate the computer from virus attacks, such as immunization in humans. It is called a virus because it is similar to a biological virus that spreads by inserting itself into living cells.
Computer viruses are very dangerous because they can damage computers.
Some of the dangers of computer viruses that can be overcome with the lightest anti-virus include:
- Scramble data in documents
- Burden the computer so that its speed is reduced
- Replicates then spreads to various programs as a nuisance
How Viruses infect a computer
The lightest anti-virus is needed to protect the computer from mild virus attacks. But to cure a computer from a virus attack that has gone too deep into it, a heavy premium anti-virus is needed. Many ways are done by viruses to attack computers, namely:
Computer viruses can generally damage computer software or software.
Viruses can cause damage to hardware as well because of the excessive processing of certain hardware. For example VGA, memory and even the processor.
Viruses are usually easier to attack computer operating systems based on Windows. Because 95% of viruses that are spread by irresponsible parties are based on Windows.
Linux systems are usually more resistant to viruses. Only 2% of viruses found on Linux/GNU.
Mac systems are even more resistant to viruses, because only 1.4% of viruses are Mac-based.
Why Is It Called The Lightest Anti Virus?
As with any disease, you can find a doctor or healer. Likewise with computer viruses. Virus attacks and various malware can be prevented by using a device called an anti-virus.
This software called anti virus not only serves to prevent the entry of viruses but also removes viruses from our computers.
Computer viruses can be removed using database/database/Signature-based detection techniques, heuristics, or ranking of the program itself (Quantum).
There is what is called the lightest anti-virus because its use does not burden our computers. The program is small and can be downloaded for free too.
Some of the Lightest AntiVirus Types:
1. Smadav
Smadav is an antivirus made by the sons of Indonesia. This anti virus is light because it does not use a lot of memory and its performance can also be done anytime we want.
Smadav can protect our computers from various viruses that come to attack from all directions. Smadav can be obtained by installing the program either for free or premium at www.smadav.net.
Some of the advantages of Smadav as one of the lightest anti-viruses are:
Smadav is made as a very friendly anti-virus. He can collaborate with other antivirus on our computer. Its light weight and function as an addition actually complements the other anti-virus that we already have.
But if you want to use Smadav exclusively, it is also good enough for a computer that is used normally. Naturally, here it means not opening the internet too often, downloading, and opening certain websites which are sometimes the source of the spread of viruses.
Smadav is the lightest antivirus that also protects USB flash disks. As an anti-virus made in Indonesia, Smadav understands that there are still many indiscriminate uses of flash disks and are used on several computers alternately.
This makes it easier for the virus to spread widely. This is where the role of Smadav is needed not only to detect the anti-virus that it has known, but also to detect the presence of other viruses that reside in our flash. After detecting it, Smadav will eradicate it until it disappears without a trace.
Smadav anti virus is classified as very easy to use. No need to update every week or even every day. Smadav is quite updated about once a month. Because actually Smadav does not work based on the virus database but based on behavior detection techniques, heuristics, and whitelisting.
Even though it is the lightest anti-virus, Smadav is actually able to clean the virus to its roots. Smadav not only prevents but cleans the virus to the registry, so that the virus is completely gone from our computers.
2. Avira
Avira is one of the lightest anti-virus made in Germany. Avira was created around 1988 and continues to be updated almost every month by the owner. This anti virus works based on antivirus data.
Currently, which is spread and can be used for free is Avira Antivirus Personal. Personal use is free of charge and is automatically updated every day when we open the internet. Avira is now available is the latest version made in 2008.
Some of the benefits of using Avira:
- Avira can protect computers from virus attacks by checking every file that we open and close.
- Avira is able to detect the presence of a virus and then remove the possibility of rootkits by the virus.
- This anti virus is able to detect virus interference from adware, spyware, and phishing.
- Avira is able to detect viruses that come from emails by means of a virus scan.
- Avira is able to block access to malicious sites that are likely to spread viruses.
- Avira is able to recover the system in an attack against the use of Windows and Linux.
3. Avast
There is another lightweight foreign-made anti-virus, namely Avast. Avast is the lightest antivirus according to the results of a survey from an independent institution that cares about the spread of viruses and the use of anti-virus.
Called the lightest because it is easily accessible and its use does not interfere with other programs that are running.
Avast not only detects the presence of a virus on our computer, but also swiftly blocks any input that it considers a virus. The virus is then put into quarantine and our computer is free from it.
The Lightest Anti Virus Criteria
An anti virus can be called the lightest anti virus if it meets several criteria for its use. The criteria that have been used as a benchmark as the lightest anti-virus are:
The use of memory that is not large.
The champions on the low memory usage criteria here are Avast, Panda, and Norton antivirus.
Computer restart speed.
The winners in the restart speed criteria on the computer when finished using anti-virus are ESET, Norton, and Trend Titanium.
The size of the files installed on the computer.
The winners in the small file size criteria installed on the computer are the anti-virus Webroft, McAfee, and Spyware doctor.
Initial file speed
The champions on the initial file speed criteria included in the anti-virus system are ESET, Norton, and BitDefender.
Advanced scan speed
The champions on the lightest anti-virus criteria in the next scan are G Data, Kaspersky, and F Secure.
