Hi, I have just created a new website, and start working for SEO. The site is coming with good result unfortunately from last week when i open my site in google it will showing harm your computer recommend not to open. I don't know how to recover from this problem kindly provide your advice.
If you have a blog/forum/guest book - check it for spam. Maybe you are using to many keywords on the page or using black SEO techniques (buy backlinks)
This is absolutely wrong dear. This type of message in google come only if your site is attacked by any virus. So you have to check your server and remove that virus.
I agree with steven. It sounds like your website is infected with Malware. You will need to fix it and then apply to be reincluded. I have had this before on one of our sites it took a week to get the warning removed. I had to clean the site completely then get it checked out by this website: http://www.stopbadware.org/home/security After that ask google to reinclude and then just wait. Good luck!
Did you add any code recently? Check your files for any modifications, and remove the offending ones. Then submit it for a review via Webmaster tools, and you'll be fine.
This could be a malware. If you added some codes, try reviewing if there are "questionable" files or those that you are not certain of.
Review your site. There must be something your coding. The message "This site may harm your computer†appears when there's any malicious file or software in the site.
