I have had to fix hundreds of computers over the past several years and most of them could have been infected with one virus or another. Most of them were immediately deleted and their computers charged up with fake antispyware. The problem is that once a computer is infected, it can’t be cleaned. ซีรีส์พากย์ไทย
Viruses, Worms, and Trojan Horses are all part of the same group of malicious programs that can invade your computer, steal information, and propagate. These include Malware, Backdoor, and DNS.
Viruses spread by via software downloads. They take advantage of system vulnerabilities and don’t replicate themselves by themselves. They can be spread through email, instant messengers, and file sharing.
A worm is a self-replicating computer program. It uses a network to send copies of itself to other computers on the same system. Unlike a virus, a worm does not need to attach itself to an existing program.
A Trojan horse is a malicious program that masquerades as something else (eg a useful utility) as a distribution tactic. The simplest example of a Trojan horse is a “Script” or “Trojan Horse”. It can appear to be a useful software application, like a web browser plugin or a music file etc. But instead of making the software or the application itself, it can copy itself to your computer and make itself very hard to remove. ดูหนัง
There are several other types of programs that can make themselves known via social engineering or through regular Windows activities.Some can be spotted by comparing the contents of your computer to a database of known viruses or worms.When they are launched, the virus or worm activates and then provides its payload.The payload might be something innocuous that can be handled by the Windows operating system or it might be something destructive, such as a Trojan horse program that passes itself off as harmless software.Worms operate in much the same way. They also use network connections to replicate themselves. But instead of using a file or program as copy they use the TCP/IP connection to directly send their payload inside of your computer. หีเด็กมหาลัย
So what does all this mean to someone who owns a computer? The more competition there is in the software field the better the software will perform. That means that the prices of software will decrease. Software that is not updated will be outdated sooner. Prevention of security breaches will require updates for as long as the source code is available.
Unsuspecting users may download a virus without even knowing it. Email that is not clearly a hoax may have a virus in the addition to a “life of its own”. This could happen to anyone.Just because you think it is from a reliable source and opened it doesn’t make it so.
For further information on this topic, there are many good sources on the internet that keep that provide good information on virus programs. Many anti-virus programs come with software that tells you to ignore viruses. There are also user-friendly programs that will alert you if a virus is, in fact, on your computer. หนังxญี่ปุ่น
Spam, unsolicited email advertisements, and other annoying software are also a problem. That is not to say that they are not as serious as a virus. Spam is the common carrier of viruses. Anti spam measures have been implemented to help eliminate this threat. Spam email is still unwanted and can be nasty.
The other type of problem is a malicious computer worm. This can eradicate data from your computer, which is why it is important to scan your computer for viruses every now and then. A worm can consume so much system memory and network bandwidth that it causes a computer to be slow.
How are worms different from viruses?
My computer at least twice had to be scanned for viruses by my employer’s IT department. This happened because the network computers at the office were not secured from a remote controlled attack originating from the Internet.
The Cisco router that I was using was hacked by sending a virus to the company’s main computer via their Internet connection. Since the Cisco router is also being used to control other company’s network computers, it was necessary for me to scan my own computer for any viruses to ensure that my computer was not the next target.
How could I protect my computer from viruses?
- Use anti-virus software and a firewall
- Use software from reputable companies such as McAfee or Symantec
- If you see any unusual behavior on your computer (parasites, programs that run without your permission, etc), change it immediately. นักเรียนญี่ปุ่น
