Well, this virus is not quite
NEW - it spreads since last Thursday and all AV programs are able to detect it if they are updated. This virus contains a bug which causes that about 10% of samples sent are corrupted incances of the virus - not working and therefore not detected by avast!. We have added the detection of those corrupted samples as well - this will be included in the next iAVS update. For more info about this virus see
