Have you tried running malwarebytes free? if you do not have it installed install it and update it and run a scan. http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html?tag=mncol;1 If you cannot run malwarebytes or download the program please let us know.

They are all pretty much on the same theme, just different variants constantly released.

See http://www.bleepingcomputer.com/virus-removal/remove-antivirus-vista-2010 for removal instructions. Whilst this mentions Vista and 2010, it is still relevant and the way to go.

I just got bombed by this too. I launched out of nowhere - I wasn’t even browsing at the time. Must’ve been on a timer.

I had full up to date Avast running at the time but it didn’t notice anything. I immediately ran a full system scan using Avast - but again it didn’t detect anything (even though it was running in plane sight).

The bogus virus checker program appears as wscntfy.exe in the process list - and launches a fake scanner process called bdj.exe whenever you try to run anything.

I tried following the instructions linked above to install MalwareBytes - running fixreg.e then the MWB setup - but it still blocked me when I tried to install MWB (looks like the fixreg thing didn’t work - it’s still blocking every exe)

Then I tried booting up in safe mode + networking. Running MWB off a memory stick. But it blocked me again and instantly lauched the fake XP Virus scan page.

I am now worried it’s got onto the memory stick - and infected my MWB setup.exe - so I’ve ditched that thumbdrive.

Not sure what to try next - system restore? Wipe the HD? Very alarming. Any advice would be much welcomed.

Many thanks Pondus - your link worked for me (I think, touch wood etc).

I used method 2 - renaming the “wmi” file (was called bdj.exe in my infection)

Then installing Malwarebytes of a flash drive using the suppied regedit fix (had to rename it to MWB setup to explorer.exe to get it to run)

It found 5 items - rebooted - managed to connect to the internet and download the latest updates for MWB - scanned again - found 2 more items.

Rebooted - now performing a fullscan. Looking good so far. By my confidence in Avast has been severely shaken.

these rogues are not easy to detect.....but are a malwarebytes speciality

Fake antivirus overwhelming scanners

you should also remeber that Malwarebytes is a specialised tool with only a bit over 300 000 signatures while avast are in the millions, so you need both. avast will detect lots of stuff MBAM will not

Many thanks for the info. I read about fake anti-virus ages ago on The Register - but you never think it’s going to happen to you - because you’re smart - you have all the latest anti-virus, windows updates, never visit dodgy websites, never download anything… and then BAM!! Very scary.

Pondus and DavidR - thanks for your help. Might I ask; do you think this particular fake ‘XP Securtiy’ rogue is likely to have infected any memory sticks plugged into the PC?

Also - do you know if MWB can spot it in the dormant state - or only once it’s exploded and left a load of crap in the registry?

Thanks again.

I rather doubt that, only based on what we have seen in the past this doesn’t appear to be a target.

However you should protect your USB sticks:
“Flash Disinfector” program, see below and http://experi3nc3.wordpress.com/2007/05/10/flash-disinfector-by-subs/ - Also see http://en.wikipedia.org/wiki/Autorun

[quote author=essexboy]

  1. Flash Drive Disinfector
    Information and Download Flash_Disinfector.exe by sUBs from >here< and save it to your desktop.
    [*] Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.[*] The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up those drives as well.[*] Wait until it has finished scanning and then exit the program.[*] Reboot your computer when done.
    Note: Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you ran it. Don’t delete this folder…it will help protect your drives from future infection.
