A warning re some nasty malware

I've been away, in several dimensions, about some of which I'll update you later, but in the meantime I need to share the following with everybody.

Last Saturday, something calling itself  ‘Antivir*ouss Sec*urity Pro’ (I have deliberately garbled that name, you can guess the real words) appeared uninvited on my computer.  I have no idea how it got past my security filters – I suspect it somehow piggy-backed on a software update.  I’ll try and research this further.

Anyway, it immediately ran a ‘scan’, which reported 23 supposedly corrupt files which it couldn’t fix.  It then started to report apparent invasions, attacks etc. which it also couldn’t fix.  Finally, it effectively blocked my access to the internet, by advising me that the site I was trying to access was suspect and could damage my computer.  This included my home page, Wikipedia, and Google.  If I clicked the ‘continue anyway’ button, it got worse – I won’t scare you with the details.

At every step, I was told that I had to upgrade my protection, by giving them money and card details.) Naturally I declined to do this.  I tried to uninstall it, but it seemed to have craftily hidden itself away so as to make this impossible.

This thing is evil!

I called my software support service, who were aware of this Trojan.  I was advised that the only safe way to get rid of it is to reset the computer to ‘factory settings’.  You have to make sure you have a full external back-up of personal files before you do this, because you’ll have to restore them, along with everything else that didn’t come with the computer when you bought it.  (I started at 2.45 today and have just finished.)

This is obviously a seriously malicious bit of malware.  I don’t know how you can avoid it, but just thought I had to alert you to its existence.  If I find out any more about it, I’ll let you know – please do the same.

As an update, my brilliant brother has provided the following guide to how deal with it if you do get it:
