Firewall, Brоаdlу speaking a соmрutеr fіrеwаll is a ѕоftwаrе рrоgrаm thаt prevents unаuthоrіzеd ассеѕѕ to or frоm a private nеtwоrk. Fіrеwаllѕ аrе tооlѕ thаt саn bе used to enhance thе security of соmрutеrѕ connected tо a nеtwоrk, such аѕ LAN or thе Intеrnеt. Thеу are аn іntеgrаl раrt оf a соmрrеhеnѕіvе ѕесurіtу frаmеwоrk for уоur nеtwоrk.
A fіrеwаll absolutely іѕоlаtеѕ уоur соmрutеr from thе Intеrnеt uѕіng a “wаll оf соdе” thаt inspects each іndіvіduаl “packet” оf data as it аrrіvеѕ аt еіthеr ѕіdе of thе fіrеwаll — іnbоund tо or оutbоund frоm your computer — tо dеtеrmіnе whеthеr it should bе allowed tо раѕѕ оr bе blосkеd.
Firewalls hаvе thе ability to furthеr еnhаnсе ѕесurіtу bу еnаblіng granular control оvеr what tуреѕ оf system functions аnd рrосеѕѕеѕ have access to nеtwоrkіng rеѕоurсеѕ.

Most people think thаt a fіrеwаll іѕ a of dеvісе that is installed оn thе nеtwоrk, and іt controls thе trаffіс thаt раѕѕеѕ thrоugh the nеtwоrk ѕеgmеnt.
However, уоu can hаvе a host-based firewalls. Thіѕ саn bе еxесutеd on thе systems thеmѕеlvеѕ, ѕuсh as wіth ICF (Intеrnеt Connection Fіrеwаll). Basically, the wоrk оf bоth thе firewalls іѕ thе ѕаmе: to stop іntruѕіоn and рrоvіdе a strong mеthоd of ассеѕѕ control policy. In ѕіmрlе dеfіnіtіоn, fіrеwаllѕ are nоthіng but a ѕуѕtеm that ѕаfеguаrdѕ уоur computer; ассеѕѕ соntrоl policy enforcement роіntѕ.

What is a Trojan Virus
Hackers use Trojans to do bad things on a victim’s computer by spy on their computing activity, gain secret access to the computer to get data.
The type of actions usually are: Data deletion, data copying, Data modification, Data blocking, degrade the target computer and network performance.
Some of trojan horse virus you might found
Trojan-Downloader: this trojan will install unwanted malware program.
Trojan Droppers are sophisticated programs used by cybercriminals to install malware . Most antivirus programs cannot detect droppers as harmful, and hence it is used to install viruses.
Ransomware – It is a Trojan virus that will encrypt the data on the computer and ask for money for exchange with the decryption key. The criminals then asking a user to send money in cryptocurrency form. It is very difficult to recover the data without the decryption key. The WannaCry and Petya were recent ransomware attacks. Cybersecurity experts suggest users to implement a robust and systematic backup and recovery policy
Trojan-Banker is a malware that steals financial-related information like a credit card and online banking.
Trojan-Rootkits prevent detection of malware and malicious activities on the computer. These are sophisticated malware that provides control of the victim’s device. Rootkits are also used to make the victim’s computers to do a specific job like mining cryptocurrency this is called botnet.
Trojan-Backdoor is the most common type of Trojan. It provides access to the computer by creating a backdoor cyber criminals to access the computer later on from remote using a remote access tool (RAT). As this Trojan provides complete control over the computer, it is a dangerous but commonly used Trojan.
How does the Trojan horse virus infect the computer or smartphone system?

The answer is no you don’t need Android Antivirus when you have an iPhone or a Windows Based phone 🙂 Joking!
I already believed in the beginning that android users will become majority and this already happened. The rate of the usage of android mobile devices has been increased exponentially high.
As with other things in the world when it becomes famous, security threats will increase. The high demand of android devices has made the hackers more curious to generate malicious apps and hence to steal information.
Most of the malicious infections are done through the third-party app download. It is much easier for a developer to create an Android app compare to Apple App because more resource is available and the nature of android that open-sources where everybody can learn the source code and learn the vulnerabilities if exist.
The other source of virus infection is from a malicious website where they put bad code in it. Whenever a visitor browses the website the bad code runs and can break your android system.
To avoid this happened to your phone you must always cautious when installing an app or browsing a website. However sometimes we careless and install a bad app or browsing a fake or fishing site.
This is where the android antivirus function, some of the big names have their own version of android antivirus.
The reason I am writing this post and give the title Avast Free Antivirus Review is that I am using Avast for more than 1 year and quite happy with its performance. My free antivirus definition are: Really free, not degrading PC performance much, I almost forgot that I have an antivirus (means Its not pop up with unnecessary news/warning).
Before I tried several “Free Antivirus programs” and finally uninstall it because of the following reasons: some antivirus will consume much power for my computer, instead of protecting the system it will burden the system. The other is just a free trial version and when the trial ends it no longer protecting the system, and another reason.
It will download the installer file (225 KB) called avast_free_antivirus_setup_online.exe. You need to run this file while connected to the internet as it will download the actual file.
After successful installation, you will be presented with the RUN SMART SCAN button, I suggested to run this procedure consisting of 4 steps.
1. Checking whether your internet browser contains threats, if no threats found, you can continue with the second step.
2. The second step is checking for outdated software on your computer, I have 1 outdated software here but that intentional purpose, so I just click the skip for now button.
3. The third is to check Malware, hopefully you don’t have any malware on the computer.
4. The fourth step is to check advance issues, I have a lot of warnings here but I choose to skip for now. To resolve this you will need to upgrade the antivirus.
Upgrading the Avast Antivirus.
To upgrade the Antivirus is actually cheap, only 15.500 rupiah or about 1.11 USD per month if you upgrade per 2 years and it will cost us 372,000 rupiah or about USD 26.2
If we decide to upgrade it will give us 60 days free trial first, so it will charge your card after 60 days, cool right. I hope that this offer still valid when I decide to upgrade.
Features for Avast Free Antivirus software
Let’s discuss the features of Avast on free version. On the left bar, you will notice Status, Protection, Privacy, and Performance.
1. Status
The status will tell you whether the system is protected or not. Make sure it always protected indicated by the green circle.
2. Protection
There are several options: Virus Scan, Core Shields, Virus Chest, and WIFI Inspector, those are active for the free version. While Real Site, Sandbox, Firewall, and Ransomware Shield are for the premium version, indicated by the padlock.
Virus scans divided into several types, full virus scan, Targeted scan, Boot-Time Scan, and custom scan. I prefer to run the smart scan option as it will scan the files intelligently so the scan time is shorter.
The core shields will protect against all major threats, these are your core defenses for blocking malware in real-time. They are File Shield, Behavior Shield, Web Shield, Mail Shield.
Virus Chest will detect and lock away so they can’t harm your computer system.
WIFI Inspector will tell your network name, and whether it safe or not for you.
3. Privacy
is consists of Passwords, Data Shredder, Secure Line VPN, Webcam shield, AntiTrack Premium, and Sensitive Data Shield.
Passwords will store all your different passwords into a safe place, so you don’t have to remember it every time you will use them.
4. Performance
includes Cleanup Premium to get rid of junk files you the system performance will always in the optimum point. Software updater will update your old software to avoid potential problems.
Driver Updater to make sure your driver is always updated to avoid the problem with the system, unfortunately, this feature is for the premium version.
Don’t disturb mode, or silent mode will suppress notification. I hope that you will enjoy the benefits of Avast Free Antivirus software as I do.
