Why is there a common virus in a computer What is the phenomenon of a virus in a computer?

Poisoning is because there is no means of defense to resist! Let me introduce you to the soft killing that I have used and feels good! You can try it out for a few days!

Gold Mountain. The national pass on him twice VB100(The whole country participates in Jinshan and Ruixing.)

Jin Shan participated twice and won twice. Rising only got once twice) I don't feel like it's taking up too much resources! It's good to be the first to kill this new technology.

The monitoring is better. The clearing ability is okay! The boss of the domestic production!

I'll give you another cracked version of Kingsoft.

Kaba. Go without saying. Kaba, known for its anti-virus toughness! It has a certain place in China. When I use it, I feel like it's a bit troublesome to take up some resources.!Novices and low-spec machines are best not to use. Everything else is ok! Official website ** address.

nod32.The world's smallest memory-intensive killer! Microsoft has used it for 4 years!

Naturally, it's not much worse! Now it's even better, I feel as fast as if I didn't pretend to be soft! The antivirus ability is okay.

It's plagiarism. I'll give you another crack.

I've used so many kills to kill soft, so I won't introduce them one by one. As for the above 3 models, I think it is best to use ( rc 殈 original if there is a similarity.) It's plagiarism) Firewall I introduce Fengyun.

Very good. I don't need a serial number. He upgrades once in a hundred years!

Some people say that Rising is so good, why not say. I think it's commercially popular. Poor monitoring.

Every time the virus can't be removed! What to say about unzipping and cleaning up occupies no less memory than Kaba. Automatic defense is even more superficial!

Anyway, I've been helping people with computers for so long. The most I see is poisoned with Rising The following is to introduce you to the safety configuration! Kingsoft + 360 Security Guard + is suitable for users with about 256 memory (that is, restore software.

Kaba + 360 Security Guard + for users with 512 RAM or higher ) NOD32 + 360+ for users with 128 RAM. It doesn't matter if you have a high memory usage. Easy to use The above safety collocation is good.

I haven't been poisoned in so long! All of the above is a personal experience.

Patch the system often, many viruses are invaded from system vulnerabilities, and often scan for Trojan viruses, the main antivirus software with a card or Rising, the auxiliary with 360 security guard, windows cleaning assistant, do not go to the small**, but also pay attention to mobile devices, install firewalls, configure good rules, so as to greatly reduce the chance of viruses, but also reduce the risk of stolen numbers, this is the right way to prevent the harm of Trojans, the following measures should be taken: First, Install antivirus software and a personal firewall and upgrade it in a timely manner. Second, set the security level of your personal firewall to prevent unknown programs from transmitting data to the outside world.

Third, consider using a browser and email client tool with good security. Fourth, if you use IE browser, you should install the card security assistant to prevent malicious ** from installing unknown software and browser plug-ins on your computer, so as not to be invaded by Trojans.

It's easy to tell if your computer is poisoned. As long as you open the task manager, take a look at the performance, CPU usage, and memory usage.

can know. CPU usage and memory usage generally do not exceed 60 percent when nothing is turned on.

If it is exceeded, the virus is running in the background!

Hello users:

There may be abnormal network traffic, pop-up ads, account loss, inability to use antivirus software, system freeze, remote control, etc.

I usually move the mouse by itself, and QQ sends messages by itself.

Most antivirus software will prompt you.

You don't have anti-virus software installed. And you don't have any Trojan proof software. It is recommended that you install Kaba + 360 Security Guard, which is very good, and is not only anti-virus, but also anti-Trojan and malware.

。Sometimes, malicious programs can get on your computer, so you'll need to turn on your firewall!

Because the computer can install software, the computer is controlled by software, and the virus is also a software, the difference is that the virus does not listen to your command, and accidentally enters your computer and controls the computer indiscriminately, so it is ......

Because Windows has a vulnerability, if there is a vulnerability, you have to patch it, and if you don't want to patch, you can install antivirus software, and if you don't install anything, you will be poisoned.

Viruses mostly invade the system through vulnerabilities.

Of course, Linux and Mac

There are very few viruses in OS, but there is too little support.
