Windows 7: Windows 7 running very slow, loss of internet, firewall down.

Windows 7 running very slow, loss of internet, firewall down.

I am having a nightmare with my windows 7 64 bit home edition. It is running extremely slowly. I have lost the internet connection and the windows firewall has turned off and cannot be turned back on. Whenever I boot up i get the message "failed to connect to a windows server" The event viewer log is also unavailible.

I have established that my internet is working on other machines. I have also attempted to reset winsock in safe mood. However this has not worked.
I've had the system for about 9 months with no major problems. I have McAfee and have run windows defender and adaware so I am pretty sure it's not malware. I really need some assistance here. Thanks

I suggest getting malwarebytes and doing a full system scan just to be sure it's not an infection. The symptoms point to a possible infection, do a scan anyway to be on the safe side, never hurts. It's highly recommended, free and trusted by many users here. Other than that, might be something that you've installed. Any new and recent updates?

I am unable to connect to the internet. I am writing to this forum on a borrowed laptop. How would I be able to do a scan? I haven't updated anything recently other than perhaps the usual java update. I have had persistant problems with windows trying to update ie version9 which was also unsucessful. I am aware that this is not an uncommon problem.

Hi blueknighuk, you would need to download the Malwarebyte setup.exe file on te working computer, transfer it to a USB Device, Data Disk, External HDD, anything.

Then insert the device on the infected PC, and run the setup.exe.

Hope this helps

I have just run a scan with malwarebytes. No malicious files were found. I'm sure it's not a virus or anything. What I am pretty sure of is that this is a (another) bug in windows 7. I just wish I knew how to fix it.

Have you tried AVG, SuperANTISpyware, ESET, etc?

If you have a Restore Point, turn your computer off, press F8 during boot and select Restore Point or the factory install option so it restores to a point before this happened.

Thanks for all the replies guys. I will try various the virus removal software. However I am of the opinion that something has gone wrong with windows 7. I am thinking that I am going to have to either attempt a restore, or to reinstall windows. Neither of which I have attempted before. Any ideas or suggetions along these lines would be most appreciated.
