I've had this type of popup before except with the quote "press ok for mom's spaghetti" and "Thanks love you all" which popped up a couple of times. That was 2-3 weeks ago from now and I believed that I had gotten rid of the annoying virus, which this thread of course shows I did not.
Any help would be much appreciated.
Updated: This messages also popped up -
which seem to show that the virus is looking for a file in System32 which I deleted as I thought that was the cause of the virus, this file would spam upon logon and cause my computer to log out after about a minute.
Thanks so much for your help videoediting. The Malwarebytes anti-malware detected 115 malware on my computer of which where hidden Google Chrome extensions and malware .dll files. I had my suspicions that the virus may be hidden within google chrome as when I opened task manager at the time of the pop-up there were no other applications open apart from google chrome. Thanks again for your solution
