WinErx03 Scam Creates Panic for PC Users

A New Look to An Old Scam

The fake virus scam is not a new concept.  We’ve actually dedicated ad campaigns to the fake virus scam, in an attempt to raise public awareness.  However, as we raise awareness for the pop-up scams hackers were traditionally using, they began using new fraudulent error messages.  Most recently there has been a WinErx03 pop-up that displays on PCs.  According to Microsoft, this malicious pop-up will claim the following:

“Your windows system is damaged WinErx03 -Please note: Windows security has detected that the system is corrupted and outdated.  All system files will be deleted in…”

Then it shows a countdown of seconds ticking by, and goes on to say,

“Windows Firewall has detected that you have not updated your windows system,  It remains damaged and vulnerable.”

Please know — this is fake.  The scammers designed the pop-up to generate a sense of urgency for the user to call as quickly as possible before investigating the legitimacy of the alert.

Fortunately, this is just a scam and not a virus.  Unfortunately, that means traditional antivirus programs won’t stop it.

  1. I have been doing this on my own for a couple of years now when I get a frightening scam like this to get in touch with Microsoft. I didn’t believe them and on my own figured out to do the task manager thing. Only thing that works.
