Update removed my svchost.exe file how can I get it back1 person needs an answerI do too

I had the same problem ... I copied svchost.exe from the C:\WINDOWS\ServicePackFiles\i386 directory (14 KB - I'm using WinXPSP3) to my C:\WINDOWS\system32 directory (as I recall, I did Start->Run->cmd and explicitly used the "copy" command). I then rebooted the machine. [This worked for me ... ymmv but it's worth a try]

Try to use system restore. It is suspect thing that McAfee will NOT do such thing unless it detect as Virus. Also contact McAfee support for help.

I cant even use system restore or even windows search or get in to McAfee itself

seriously, dude, try copy'ing that file ... the svchost.exe wasn't a suspect file -- it was just a monumental mistake by mcafee. i, too, had system restore turned off and couldn't restore back to before the disaster struck. i copy'ed the svchost.exe file back in, rebooted, got back on the 'net and d/l'ed the *new* mcafee definitions file, ran a full scan and all was well. (btw, after that, i turned system restore back on so i'd have a restore point in case of a future disaster). mcafee never said that the svchost.exe file was suspect - just that their bogus virus definition got out into the wild and wreaked havoc on the world. funny that it only affected XPSP3, huh?

Try to run in safemode and see what will happen: 1)restart your Pc 2)press F8 continusly 3)chose safemode They try those steps.I also recommend you to contact McAfee support for help with this.
