Computer virus protection

The computer virus continues to hit.

Computer viruses (hereafter referred to as "viruses") are programs that cause various harmful effects, such as destroying or falsifying data on other people's computers or stealing personal information such as passwords, via the Internet (e-mail or browsing home pages) or USB memory sticks.

Viruses spread to PCs worldwide via the Internet. Many viruses have built-in functions to spread through networks and USB memory devices, using the infiltrated (infected) PC as a foothold to spread and cause more damage.

These viruses are also the most significant cause of interference with the operation of any information system.

We operates an anti-virus system that checks files attached to e-mails sent and received at the university for viruses. However, because some viruses can slip through the anti-virus system, it is essential that PCs also be protected against viruses.

To detect and get rid of malicious programs, all computer owners must install "antivirus software" and update their "definition files. OS updates must also be performed in conjunction.

What should I do if I get a virus?

When performing virus removal, always disconnect the computer from the network.

【MOST IMPORTANT】

  • If you think your computer has been infected with a virus, first disconnect it completely from the network.
    If a LAN cable is connected, unplug the LAN cable from the computer once.
  • With the computer disconnected from the network, use antivirus software to check for viruses. If no virus is detected, please contact us.

Where can I get antivirus software?

    • If you do not have antivirus software, please purchase your own.
  • There are also free virus scanning tools that you can try.
  • Apple Macs are said to be relatively resistant to viruses, but there is still a possibility of infection, so it is necessary to install antivirus software.

How do I update the definition file of my anti-virus software?

  • Even if you have antivirus software on your computer, it is useless if the "definition file" containing the latest virus information is not updated.

What measures or tips, other than antivirus software, can be used to prevent viruses from entering the system?

  • Stop the autorun function (Autorun) in order to prevent virus infection from USB memory sticks, etc.
  • Don't reuse the USB stick.
  • Check the usage history of the USB memory stick, and if there is a possibility that it was used on a PC without virus protection, be sure to perform a virus check.
  • Do not carelessly open suspicious e-mail attachments.
  • Do not access websites linked to in the body of suspicious e-mails.
  • Installation files of free software may contain viruses, so do not easily install free software just because it is convenient or free.
  • Do not visit dangerous websites such as adult sites, as you may be infected with a virus just by browsing websites.
  • Do not be misled by warning messages such as "You are infected with a virus" that suddenly appear and do not install the "fake antivirus software" that you are led to.
    If you are unsure, talk to others around you or to us.
  • While browsing the website, do not install the "fraud software" to which you are directed, being misled by fraudulent advertisements such as "Is your PC slow? "or" PC performance is slowing down".
  • If you still see ads, delete all browser history. If you still see ads, please remove any programs installed in your browser that are causing ads to be displayed incorrectly.
