Firewall PC Virus
How does a virus successfully enter your system and affect the functioning of your firewall software?
A firewall is a device that blocks illegal access while permitting authorized communications. These firewalls can be implemented in either hardware or software. It filters the information that comes through the Internet into your private network or system. Therefore, a firewall safeguards your system from viruses,Â Trojan horses, bots, worms, etc. Some firewalls andÂ antivirus softwareÂ products get disabled by viruses that enter the network and leave the system vulnerable. It spreads all through the system due to which you might receive antivirus prompts for enabling the phishing filter. Hence, after pressing ‘OK’ you automatically get connected to the Internet and download more malware on your system. This results in corrupting registry entries and DLL files and disabling the functions of your firewall. Furthermore, it crashes the operating system.
Below, mentioned are few ways in which a virus can enter your system:
- Harmful websites and links
- Auto-play options
- USB driver with autorun.inf files
Harmful websites and links
A virus creeps into the system through Internet in case if any harmful website or link is visited. It remains inactive until you execute any infected program or start your computer from a disk with infected system files. It becoming active and loads into your system’s memory and hard drives after you run that particular infected program. Hence, it is recommended to download antivirus files by typing the address of the respective site in the address bar and then downloading it.
An auto play option in your system is the main door through which a virus might enter into your system. When you attach a USB drive or memory card to the computer then the auto play option gets enabled. Hence, you need to disable the auto play option and scan the drive with antivirus software immediately.
USB driver with autorun.inf file
Every USB driver contains an autorun.inf file that is commonly used by all users. Hence, a hacker may use this file to damage the system and get access to confidential data. So, it is recommended to format the USB drive and create a folder in the name of autorun.inf after opening the formatted USB drive. This prevents the autorun.inf file from entering into USB drive from any system.
