I seem to have an issue with my computer which is preventing anything security related from working effectively. I had a number of pieces of malware etc on the computer, but think I have removed them. I have run full scans with Avira, Trend Micro online, Spybot Search and Destroy, IO Bit Malware fighter and C Cleaner to try and get rid of everything and tidy it up. I can't see anything left on the computer now that looks harmful, however I am having the same issues.
Any anti virus I install won't allow me to run real time protection. I have tried installing and re-installing Avira, Avast and AVG and none allow real time protection to be run or updates to be run. On top of this Windows Defender fails to run and Windows Updates won't run. Other than this the computer appears to be running fine with no performance issues or issues with pop ups.
Windows update says it cannot check for updates because the service is not running.
Windows Defender says the specified service does not exist as an installed service.
The Anti Virus programs throw back various errors or just fail to turn on. I'm very conscious I'm not protected without this and Windows 7 will not be up to date without updates on. I have checked to make sure all previous anti virus software has been uninstalled. Please help.
