A couple of days ago, there was an advert for the "Mediocre Modeler Group" on the Mayhem Facebook page.
Out of curiosity I clicked on it. My monitor immediately flashed blue (with text - but too fast to read) and the computer shut down.
Now, something that can shut down my computer is obviously up to no good, so I restarted in safe mode and ran Malwarebites.
This threw up 11 changes to both programs and registry which I quarantined (can't have too much quarantine!).
Today I have received multiple warnings from Google that my account access is being attempted by someone else.
I've had to change my passwords, including Mayhem (which I know I should do regularly anyway) but its a 'round tuit' job.
Hope no one else has suffered from this.
Bl**dy viruses!!!
