[pup.optional.winyahoo keeps returning]

Sorry Aura, it's all good now. 

Thanks,

[pup.optional.winyahoo keeps returning]

Every morning I open my computer to the MB scan showing it quarantined pup.optional.winyahoo . Nothing I do will get rid of it.

I have run FRST and have attached the results in two files along with the MB scan

Please help, thanks.

[Malware Pro hangs at HKLM...]

Thanks - I'll watch it and see what happens

[Malware Pro hangs at HKLM...]

Running Vista Home Premium 32bit - all hardware tests are OK - the machine was infected as follows but MS Security Essentials claimed to clean the machine

Trojan:Win32/Bamital

Trojan:Win32/Bamital.J

Backdoor:Win32/Cycbot!cfg

Trojan:Win32/Sefnit.O

Running MSE doesn't reveal any problems but

Malwarebytes hangs at hklm\microsoft\windows\currentversion\installer\userdata\s-1-5-18\componenets\ various keys

as well as

hklm\microsoft\windows\currentversion\shellextension\approved\ various keys

The only way to free the machine is to do a hard reboot.

CHKDSK runs on restart and fixes various files like searchprotocolhost.exe and software.old

Is this a result of the registry being badly corrupted or are there any other suggestions out there that I could follow before backing up and reinstalling Vista?

Thanks

Here is the entry from the Startup tab in the System Config window

ewecoqafar - rundll32.exe "C:\Windows\ewecoqafar.dll",Startup - HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

MBam scan reveals no problems

MS Sec Essentials found bubnix.gen!A and got rid of it but it came back. I did another scan and it now shows as clean... nothing found

Any assistance is appreciated, thanks
