What happens when DNS is often wrong

Causes DNS frequent error cause analysis

⒈ virus in computer

If the computer virus is generally malicious software tampering User homepage, hijacked computer DNS, etc., causing the computer to open a well-known website will jump to other malicious sites, or simply can not open the site.

Solution: Use antivirus software to scan the computer first, check whether the computer virus, whether there are anti-virus software related tips. If the anti-virus after the page can be opened, mostly because of the cause of the virus.

⒉ website failure

When found to open some Web site will appear DNS error, but some major stations to open all normal, this situation most due to Web site domain name server failure or Web server failure. There is also a situation in the network service providers (such as telecommunications network services server failure, there will be a similar situation, mainly due to line congestion caused by a common local area of the Web site is inaccessible, with a regional, generally such cases rarely occur).
