Warning! Fake Quill Invoices
Be aware that there are fake emails from Quill.com whomever they are, floating around.
Dear Customer, Your most recent Credit Card Purchase Receipt from Quill is now ready to view online.
The spoofed links in the email do not point to Quill's website, nor are they directed to a PDF as stated, they point to a encoded url which is probably going to be a self-running php file that infects your computer with malware or worse, encrypting your files with one of the many Crypto-scams currently infecting many computers.
NEVER click on suspect links in emails that you do not recognise or are expecting and never ever agree to give these scum a call or money, if infected, contact a local competent and recommended computer firm for advice.
