Windows 7: Can't log in when wifi is on, following a restore

Hi guys

Here is my problem:

I can't log in when the wifi is on (laptop) and when I do log in (wifi off) I can connect to the router but I can't see the m: drive on the network.

This is following a spyware contamination and a system restore

I've tried resetting the credential manager (services and registry) but still not working

Hello Guitarboyled, Welcome to Sevenforums. Is your computer local or on a network?

First, are you sure the system restore was before you were contaminated? Did you check for any other viruses or malware? What antivirus are you using? Malwarebytes is an excellent malware remover. If you have no AV, consider also using MSE

I will post links to some tutorials that you should go through and see if they fix the problem:
SFC /SCANNOW Command - System File Checker

Do this next one 3 times Startup Repair
