Is a PC free from viruses when disconnected with internet?
OT, but viruses will do just fine. Notwithstanding what you might see in a supermarket (e.g., banana's), noun plurals aren't formed by adding "'s".MikeeMiracle said:Most virus's (virii?)
This is all true, but where you need to worry about things like this, there are almost certainly system administrators in a secure facility who are in charge of security. It's a very complicated thing. For home use, you probably can do ok with scanning any media, always updating good security software, and being careful on the internet. So we really need to know how the PC will be used (home private use, company use, classified use) before we can give a good answer.MikeeMiracle said:Computer virus's were around a long time before 99% of the population knew what the internet was. It was transferred by floppy disks when people copied data between computers.
Most virus's (virii?) back then were destructive and made by people who thought anyone with less knowledge about computers than themselves didnt deserve to have a computer. These days it's more malware which aims to steal data from your.
The proper term for having a computer network disconnected from the public internet is "air-gapped" but even then, nation state actors have devised method of overcoming this. These methods include measuring magnetic fields from your CPU, power fluctuations in the supply, blinking an LED on your computer which is then picked up by a camera external to your PC like a security camera and even using the computer's speaker to emit sound inaudible to the human ear.
I think that is much too strong a statement. With reasonable care, I think one can be fairly safe. But it is good to be aware of the dangers.Dr Transport said:a computer can only be completely virus free if it has never been attached to the internet
And never receives information via other methods that can transfer executable code, such as disks (flash drives), a keyboard or a microphone. By nature, being infect-able is a consequence of the intrinsic purpose of most general purpose computers.Dr Transport said:a computer can only be completely virus free if it has never been attached to the internet
When disconnected from the Internet, your PC is relatively safe from external threats such as malware, viruses, and hacking attempts. However, it is still vulnerable to internal threats such as physical damage, data loss, and unauthorized access.
Yes, you can still use your PC without an Internet connection for most basic tasks such as document editing, playing offline games, and watching local media. However, certain features and applications may require an Internet connection to function properly.
Yes, it is recommended to have antivirus software installed on your PC even when disconnected from the Internet. This will help protect your PC from any potential threats that may have been introduced through external devices or from previous online activity.
No, it is not safe to connect your PC to public networks even when it is not connected to the Internet. Public networks can still pose a security risk as they may have been compromised by other devices or users.
While the likelihood of being hacked when disconnected from the Internet is lower, it is still possible. Hackers can gain access to your PC through physical means or through previously installed malware. It is important to take precautions and secure your PC even when not connected to the Internet.
