  • Today I'm going to talk to you about malicious software, also known as malware, and how you can protect your computer from infection.


  • First, let's talk about how you get malware.

    今日の話題は 不正なソフトウェア

  • Malware is often installed on your computer without your knowledge when you visit certain websites.

  • Malware may also be installed when you download a file that appears to be legitimate, but is actually doing things that you didn't want or expect it to do.

    まずはマルウェアの 感染ルートですが

  • Malware has been known to do things like delete data on your computer, steal personal information such credit card numbers and passwords, send spam email, or even attack other networks and computers.

  • One of the most common symptoms of malware that our users report is being taken to an unexpected site after clicking on a search result.

  • To avoid malware from infecting your computer in the first place, it's a good idea to follow a few general guidelines.

  • There are a number of programs that can remove the most common malware, although you may need to try more than one to catch every instance on your computer.
