Sudden share problem

Specs: Windows 7
I'm having a huge problem, I use windows 7 64 bit.

I ran some stupid program to remove an msn virus (not that I had one) to test it for a friend of mine.
However since I did my pc seems to have problem sharing it's files over our network. I can see all other pc's on this one, just not vice versa.
I can ping all pc's, but again, not vice versa.

I tried checking if this was due to a firewall modification, but I notice my firewall isn't on.
For some reason I tried starting my firewall by pressing "Use recommended settings", but apparently there's also something wrong with my firewall. I received a message:
"Windows Firewall can't change some of your settings. Error code 0x8007042c".

I then noticed in Services that my Windows Firewall service is not started, I tried starting this and I received a message:
"Windows could not start the Windows Firewall service on Local Computer. Error 1068: The dependency service or group failed to start."

I tried checking all depedency services by clicking right and checking the correct dependencies, they were all started.
According to another forumpost I notice that here they say u also need Windows Firewall Autorization to be started. I notice I don't have this service, also when I check device manager/Devices by connection/Show hidden devices I don't see a Windows Firewall driver.

I tried using "SFC /SCANNOW", it said it repaired some stuff, but nothing changed after reboot.

Then I tried changing the permissions on certain services according to this page: http://support.microsoft.com/kb/943996

Still no success

I also tried running these commands:

C:\Users\Yannick.Yannick-PC>sc queryex mpssvc

SERVICE_NAME: mpssvc
TYPE : 20 WIN32_SHARE_PROCESS
STATE : 1 STOPPED
WIN32_EXIT_CODE : 1068 (0x42c)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x0
PID : 0
FLAGS :

C:\Users\Yannick.Yannick-PC>sc qc mpssvc
[SC] QueryServiceConfig SUCCESS

SERVICE_NAME: mpssvc
TYPE : 20 WIN32_SHARE_PROCESS
START_TYPE : 2 AUTO_START
ERROR_CONTROL : 1 NORMAL
BINARY_PATH_NAME : C:\Windows\system32\svchost.exe -k LocalServiceNoNetwork
LOAD_ORDER_GROUP : NetworkProvider
TAG : 0
DISPLAY_NAME : Windows Firewall
DEPENDENCIES : mpsdrv
: bfe
SERVICE_START_NAME : NT Authority\LocalService

Again no success

I also tried system restores, but these failed...

I have no idea if this is all related with the fact that I can't share anymore.

I am a bit out of ideas

This sounds like a virus. What was the program called?

The fact that all these settings are gone/shutdown and you are unable to change it makes me think a virus got in.
