Viruses and worms

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 ?

  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.
