Can an MP3 spread a virus to your computer?

Yes, but there have not been any reported mp3 viruses for PCs, Macs, or Linux computers. But there has been one confirmed mp3 virus that attacks ipods.

Somebody thought that files must be executable to infect a machine, but this is not accurate in my opinion. A cleverly crafted data file can take advantage of flaws in existing software to cause unexpected behavior, which may include adding, replacing or deleting files. There have been many reported vulnerabilities reported (and fixed) with the code in web browsers that displays images (jpeg, gif, etc) some of which have allowed execution of arbitrary code. There is no reason that similar vulnerabilities might exist in mp3 player software, as the link above demonstrates.]

Keeping your computer up to date with operating system fixes should help minimize the risk, which is already fairly low, as would not downloading mp3 files from unknown sources. These kind of attacks are also very specific to a particular operating system and software. Virus scanners generally don't even look in image, audio or video files, because there have been few or no examples of this sort of virus.

Why your computer restart while loading?

Try hitting F8 a whole bunch of times when it restarts. Keep hitting it till it says safe mode on , then move the cursor to launch "safe mode with networking".

Does hacking mess up your computer?

If your computer is "hacked", it means that another person has infiltrated your computer through some means. (Usually over the internet.) Depending on how your computer was hacked, hackers may simply gain access to your shared files or gain the ability to use your computer as a proxy. However, if they gained complete control of your computer through the use of a virus they may be able to steal passwords, track your keystrokes, and do generally anything they want with your computer.

How Is posibale Norton Antivirus the best for your PC?

Answer

The idea of software being the "best" is very subjective. What is best for you isn't necessarily what is best for me. The relativity of what is "best" is due to the varying experiences, needs and wants of people. In the case, of anti-malware software the idea of what is better gets even more unclear. Quality software in this category has to do well in a number of areas such as user interface (how the program looks and how easily a user interacts with the software), protection from a number of threats, up to date malware definitions and its impact on system resources.

I personally do not use Norton but from its reviews and my own personal experience I would say it is atleast decent. To be honest, every tech company will claim their product is the best. They want you to buy their products rather then supporting their competitors. I personally use Avast Free Antivirus. I find it offers exceptional protection especially for the fact it's free and the user interface is decent (Though easier to use in the past). You can download Avast Free Antivirus
