What should I do if my computer is always attacked,,,

You add my mailbox, and I'll send you a good firewall, which is free forever.

Please specify Firewall.

If it's blocked by a firewall, it's fine.

The firewall indicates that the system has been attacked.

The so-called "attack" of common personal firewall programs is not necessarily a real network attack, and many firewall programs will use the most common network access, such as network broadcasting, as an attack to alert us and record it (especially in local area networks). Another "attack" could be someone scanning your computer's ports, or someone else being infected with a virus that is using the infected computer to scan other computers on the network.

In general, as long as you update your system patches regularly, these so-called "attacks" generally do not pose any threat.

Personally, I think that this kind of prompt of the firewall program is just a kind of "advertisement" in disguise, you see how useful I am, how powerful it is! There are so many attacks on the Internet, I have blocked them for you, there is nothing wrong with using me! If there was an attack and it told you that it wasn't blocked, would you still use it?

I guess you're going to change your firewall right away, right?

After you only enable Kaspersky's "stealth login mode" for a while, the hacker can't scan your IP and won't attack you again.

If you don't understand anything ... To reinstall the computer, it is best to format the hard drive.

Disconnect the network and reinstall the system.

Catch his IP for anti-intrusion.

Just be defensive.

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 theft, this is the right way to prevent Oh.

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 okay. I'm having the same problem with the book and I get this:

How do you know if your computer is under attack on a regular basis?

In fact, there is no need to be so nervous at all.

If the information of the attack came from the firewall, then there is nothing to worry about, since it has detected the attack, it will naturally block it.

It's just that many firewalls will also lie that they have found an attack and make users think that the firewall is good and often intercept attacks.

In fact, it is not uncommon for PCs to be poisoned, and they are rarely attacked (unless you leave the system loophole open to welcome hackers).
