What is C:\WINDOWS\system32\svchost.exe

[BuvDeep]

I was testing my PC since last three days and found that when windows\system32\svchost.exe is running and using my Internet connection, I wasn’t able to browse internet. And when I kill it my internet works fine. I did some searches on internet and found many people saying it is a virus whereas few says its not a virus.

In order to confirm it I ran my Norton Antivirus but it wasn’t able to detect it. So if it is not a virus why am not able to use internet when it is running? Somebody please help.

Who said it is a Virus? Dude, its not any virus, in fact it is one of the moist important files of Microsoft. You should not block it at all. As far as your internet is concerned am sure that would be some another reason for the same because this svchost.exe use to run everytime with your computer whether your system is connected to internt or not, so this couldn’t be the problem.

My problem is that antivirus softwware can't seem to go past this file. it scans until it hits it and then says an error has occured so I am not able to scan the rest of my computer as i do not have the option to skip that particular file.

Any ideas or help regarding how to replace the file/fix it or what might be happening?
