Hi, Working on cleaning an infected machine for a business customer. Ran combofix and removed quite a few infections. I then ran adwcleaner, again lots of registry keys/services,etc found and removed. After rebooting however, I do not get a user account to click on when I reach the Windows 7 welcome screen. If I boot in safe mode, I can logon no problem. Everything looks fine.

This particular machine is running important software for the customer and a reinstall would be very much a last case scenario and a major headache for everyone involved!...


Here's what I've tried so far.


1- Tried creating another user account in safe mode. No luck, it appears to allow me create the account but no accounts appear.

2. Changed how users log on, to prompt for ctrl-alt-del (currently logging on by clicking on the win 7 animal avatar,etc). Once I reboot and press ctrl-alt-del, I am left with the same screen as the previous logon type. Just a blue windows 7 screen, with windows 7 professional at the bottom. Everything looks normal apart from there being no option to log on or select a user account.

3. Tried system restore - no luck.

4.Tried last known good config - no luck.


Next option is an sfc scan. Also running a malwarebytes and eset online scan at the moment which are finding further infections.


Anyone seen similar behavior before??


System is Windows 7 Pro SP1. In a workgroup enviroonment.


Thank you.

After Malwarebytes found and quarantined another host of infections I was able to login as normal. All fixed now! Thank you.
