AVG Free in August in France?
 

Traditionally nothing much works very fast in France in August, has my AVG Free joined in?
I'm running a Dell laptop, Pentium (R)M ,1.5GB RAM, Mozilla, Windows XP Professional 2002 vesion 3 and run Ccleaner daily but AVG Free has come up with "Genereal Behaviour detection" and quotes: - windows\system32\rundll32.exe
and "Trojan Horse Crypt2.AKQM" and qoutes: windows\system32\nwcfga.dll

When I try to remove the threats with AVG Free it says "failed" (It also fails if you start in Safe Mode and run AVG).

PC is in go slow mode. Any ideas out there?

A quick Google produced this: How to Remove Trojan Horse Crypts | eHow

Also I would follow up with: Malwarebytes : Free anti-malware download

Best of luck - let us know how you get on,

time to dig out your DOS skills

You need to boot the PC with a Windows CD and drop into the recovery console, or else use a "live" CD such as VistaPE and then delete that file manually
You then need to do a clean up of the PC......and quite simply AVG is not up to that
I've posted numerous times the steps needed to clean a machine....PM me if you need a refresher, I'm not posting them again

But believe me, just removing that file won't be enough -- there WILL be other crapware on that machine

I had that AVG general behaviour detection a couple of times and wondered if it was a false positive.
AVG asked if I wanted it removed then said it couldn't remove it.
At the same time it was saying that computer was safe.
Malwarebytes found nothing.

See my previous post on AVG. To recap I wiped it from my system and reloaded the latest version (looks quite a bit different, I didn't object to the former version but that is "progress".) New version works faultlessly.

UPDATE: Tried various suggestions; then as suggested by MM (see above) I left AVG Free in place, went into Safe Mode and ran Rkill, Hitmanpro, then tried to run Combofix - this caused the system to crash.
I then uninstalled AVG Free and tried the above again, the system crashed again.
I then installed Avast (free) and tried again, the system crashed again.

None of the (free) Malware/Antiviral programs I tried found any problems or, indeed, any Crypt2 files.

As I couldn't get "Combofix" to run I finally (more in hope than expectation) emailed the Avast Help system. I received an automated reply immediately and a real reply within 24 hours, I have since had a further three immediate emails from Avast. Their last suggestion was: -
Run Avast in Safe Mode
Run Avast browser cleanup
Run Malwarebytes' Anti-Malware
Run Spybot
Re-boot

This procedure identified two Trojan Crypt2 files!

I am most impressed by the Avast Help system, so much so I will be buying their system. I anyone needs the full Avast procedure please PM me. Also many thanks for all the help given on pprune.
