I have go across this 4 times this week. My customers for getting a virus/trojan which appears as only number in task manager. For example: 4170169061:44075829.exe. The number seems to change on different computer. I have tried everything, from removing the enties from the registry to scanning the drive external in a USB case, but no luck.
Has everyone else seen the virus or have a removal tool. I even contacted TrendMicro and they stated, I have never heard of the virus like that.
The only thing left to do is rebuild the PC.
