#What is malware?
Everyone also heard the words such as malware and virus. In the first place, what is the virus / malware originally?Malware is malicious malicious software and programs that can adversely affect us such as data theft or destruction. In other words, malware is a collective term for viruses, worms, Trojan horses and other things that have a negative effect on computers.
There is malware called logic bomb, but it is a virus that destroys all the data on the computer until it runs out. I mentioned one example, but it is quite a powerful virus. So, how does malware actually invade our electronics and cause damage? Let's start with the infection route.
#Malware infection route
The first type is"web browsing type" in which a specific site is browsed and viruses invade from there.
The second is "mail attachment type" which infects by opening the attached mail file.
The third type is "USB type" which automatically executes programs when USB memory is connected to PC.
Malware that intruded from these routes causes operations such as alteration, deletion, leakage, etc. on the data on the computer, and in the worst case it may be used for attacks to the outside (cyber attack, etc.). Recently, there are instances where IoT devices with weak security (weak) are infected by viruses and used for external attacks. (Recently Mirai malware became a hot topic)
#Malware countermeasures
The most effective thing from these malware is to use antivirus software (security software). (Click here for security software) By using software, it is also possible to discover and delete programs that scan inside PC and act suspiciously. Also, there are many integrated countermeasure software that can now take anti-virus measures on the net.
Security software ranges from free to very expensive.There are differences between them, whether there is support, the number of services and so on. Although it does not mean that quality is bad and not useful as it is free, there are problems such as lag (time difference) from discovery of vulnerability (weak point) to correspondence is large, and many fake software exist. (For details, please see the page of free software.) Tentatively, using free things may be a hand.
As another method, not to skip updating the OS also becomes a very important factor. In other words, it means keeping up to date. But please do not forcibly give it to Windows 10 from Windows 7 Please update frequently and keep up to date on Windows 7 even if it gets update program. The reason is that it corrects and improves the trouble from the maker, the vulnerability (weakness) of the program, and it can raise the safety considerably.
#Sumarry
First install antivirus software
Do not open unknown mails / URLs unnecessarily
#Our opinion
As you can see from the infection route of the malware mentioned above, malicious programs invade your computer and smartphone with a clever technique. If you do not recognize it, personal information may be stolen or important data may be encrypted and requested ransom. For these reasons, usual precautions such as prevention of prevention of always using the security software and always keeping the state of OS and software always up to date and not opening suspicious URLs will become very important factors .
