What causes Lenovo laptop poisoning?

1. Antivirus software is unresponsive.

Sometimes, malware deliberately disables your antivirus software so that it can protect itself from being removed. At this point, you can create a malware scanner and ask the software to find out the software that exists on your computer and remove it.

2. The computer is running slowly or lagging.

When you notice that your computer is running much slower than usual, or if the software that normally runs smoothly is now stuck after opening, then it is very likely that your computer has been infected with a virus.

Even if you don't turn it on, these malware will be the other.

The software runs in the background as well. They will take up your computer's CPU, all the remaining memory, and network bandwidth, causing your computer to run much slower.

Third, a large number of pop-ups appear.

When you notice that pop-up ads that are rarely seen are now springing up, you need to pay attention to whether your computer is infected with a virus. If you just block them as some spam ads, the viruses won't be cleaned up, and you'll have the same problem the next time you boot it.

Fourth, the computer will run at night.

When you find that your computer is still running at night when you are not using it, or you are not open and some unknown program is running. At this point, there is a good chance that your computer has been infected with a virus and may already be under the collective control of a botnet.

Fifth, some system tools cannot be opened.

If some of your computer's system tools are unusable or unresponsive, especially some system maintenance or repair tools, it is likely that a virus prevents you from deleting them and does a protective mechanism. Since the system tool cannot be used and can be replaced by other software, many people may give up using the system tool and will not find out that it is the cause of the virus. In fact, some action needs to be taken to clean up these viruses at this time.

Sixth, the visiting ** put you on the blacklist.

When you enter a web page that tells you that you have been blacklisted, you are most likely infected with a virus and most likely have been hacked by a botnet. This is a very obvious sign that everyone can usually perceive.

7. The home page of the browser has been changed.

If you find that your browser's homepage has been replaced by a homepage that you don't set or even recognize, there's a good chance your computer has been infected by malware or intrusive ads. You can reset your browser's homepage once, but this will not cure the symptoms, and you'll need to use an antivirus to get rid of the virus.
