Meme's and GIFs are a great tool to hide and load executable (.exe) files that will imbed and manipulate the coding on your computer (most likely in the root level coding).
Google Chrome is actually doing you a "favor" by screening the webpages for these types of executables before opening the page and downloading them to your computer.
Most Anti-virus software programs out there are not able to detect and prevent these malware attacks from occurring because they typically are passive in nature vice pro-active in nature (like Google Chrome). Combine that with how the malware is coded to enable it to imbed itself within the computers coding backbone, and most of these executables are virtually invisible to your Anti-virus software.
Search, download, and run "malware bytes" and then "malware bytes root". That should clear any imbedded files on your computer. If you still have issues with Google Chrome at that point, there is something downloaded on the forum, probably a pic or gif, that is actively infested with these executables. In which case, if those files are not deleted from the forum, you will probably need to download Firefox and remember to routinely clean your computer with the 2 malware bytes programs.
Scott, based on how many issues you are having and for how long, like i said in the other thread, you need to run those 2 files listed above on all your computers. If that does not fix it, let me know...
