I've been getting these alerts for almost a week now. I ran a reputation scan and Norton says that this file is "Trusted" and "100% Reliable," but I don't believe it, because all it's been doing is bogging down my computer and causing it to crash every now and then. I also ran 2 full system scans, and still no improvements.
It all started after I downloaded Skype last week, then I uninstalled it after I realized how bad is was bogging down my computer. It runs a little better now, but it's still not up to its peak performance the way it was before this.
I tried to just delete this "svchost.exe" file, but it won't let me because it says that it "can't be deleted because the file is open," but it's not open.
BTW, this file was originally created back in July of 2009, but there was a recent update on it a week ago, after I installed Skype.
