    MAJOR Crash a form that nearly shut down my entire comp

    Asked by Michael  on February 15, 2015 at 01:15 AM

    I have had a bad experience with a form. I think it had to do with the template that I used from your gallery. After I embedded on my blog, I went to use it and it asked me to install this extension to Chrome that I was unaware was needed. And for the life of me, I can't remember the name. But I can tell you this much, Chrome blocked it for dangerous properties. Even though it was blocked, I went to use the template and everything worked fine. Then about 10 minutes later out of nowhere all hell broke loose. My site looked a gory murder scene, headers were ripped apart and strewn upside down and all around, blog posts were shattered and spread across the screen. I seriously have never seen anything like it in over ten years of working on the web. It started to shut down my COMP!! So I just wanted to give you a heads up and let you know something is defective or malicious. If you have ANY questions that you need me to answer, please ask. I LOVE JOTFORM!!! Wootie Woot. So I want to make sure you're as safe as are the users. I'll try to find the extension it installed and send it.

    Ok, I just saw how it works. The last time I clicked the link to the contact page, it had me install an extension. Now, this time that I went to get the link you need at the bottom of this form, another popup asking for dating somesuch. So, I assume something has been hacked and corrupted. Let me know what other info you need: theme type, first extension name or anything else. 



    PS: Sleek template, with my own CSS 

    PSS: I submitted a complaint to Chrome and detailed what happened.

    Hi Michael,

    I'm so sorry to know that, but I don't think the problem resides in our template or design. Your browser is probably infected with adware or some sort of a virus that automatically popups every time you access a website.

    Your website also contains a lot of ads which are blocked by my antivirus, I have a whitelisted your website so to know what are those and here are they:

    And some other random popups.

    With that being said, I would suggest checking your website source and find the ad script and remove it. I would also suggest the following:

    -Full Scan your computer to see if there are hidden virus that causes it.

    -Reset your browser to its default settings, such as the Search Engine should be Google or Yahoo or Bing - make sure it's not from the other providers that would sometimes suggest a bad links.

    -Install a popup blocker extension/plugin such as Adblock or Adblock Plus.

    -Install an extension that will protect you against untrustworthy links such as WOT (Web Of Trust).


    Thank you and I hope that helps!

    By the way, please let us know the full link of the template here from our form template gallery so we can further check. Just to make sure it doesn't contain a download link to that extension.
