WIN32: Beagle-AHD and avast.exe is not a valid Win32 application !

[clodben]

My avast software does'nt want to work, since I was infected by a trojan WIN32: Beagle-AHD. I just tried to remove and re-installed avast and that does not work !


Al the time when i try to run avast it's written that AVAST.EXE IS NOT A VALID (GooD) Win32 APPLICATION !!!! 

I just attach an image of that

HELP WHAT COULD I DO ?

(excuse my porr English , i could read English but not write it properly! I am a french canadian, speaking mainly french)

-= Be sure to turn off any on-access protection module & refrain from opening any applications while the cleaner is running..

-= Hope it helps..

1. Scan with these on-demand scanners Malwarebytes Free and SuperAntiSpyware Free.
2. Run a boot time scan of Avast! or if you run in 64 bits system then do a standard scan.
3. Quarantine all threat that look suspicious.
4. For clean your pc you can download CCleaner and Disk Defragmenter.
5. Also if im not wrong you can check with Secunia for any program unprotected or out dated. (if im not wrong)
6. Post a Hijackthis log.

I hope this work and you will find something.

If something is wrong on my post please feel free to correct it.

Thank.
