Do you get a lot of spam ? I've had thirty junk emails in my inbox today !!
I've got a spam filter, so I don't get many. But I got a bad virus last week. I couldn't open my files. My anti-virus software didn't block it. I really need to change it.
I've received an email asking me to update my bank details. What do you think ?
That's a typical phishing technique. Don't open it and put it in the bin. Oh, and change your password, too !
