Problem with Win32:BitCoinMiner-CA (Trj)

Please help me, I have some problems with this trojan. I tried everything but Avast seems not to remove this virus, it keeps coming back after some minutes. Any help would be greatly appreciated, thanks.

try this… clear your temp files

TFC - Temp File Cleaner by

any change?

if not, follow this guide and attach the logs. http://forum.avast.com/index.php?topic=53253.0

  1. AdwCleaner
  2. Malwarebytes
  3. OTL
  4. aswMBR

then a removal expert will help you when they arrive…may take some time bc of different time zone

I used TFC and so far it seems all fixed, no virus or malware alert for the moment.

I think it is clean now, Thank you so much for the help!
