Can I delete lsass.exe? svchost.exe?

I have the same problem svchost.exe right off of start up is running and nothing else will run
till I bring up task manager end task then I can start running programs again. but then later on iexplorer will run but evertime I close it an about/blank will pop up

i have deleted the lsass.exe in my system while using the anti virus. Still it is very slow and svchost.exe also present in my system. plz suggest me how to rectify this problem.

Please, do not even try to delete your svchost.exe-file. Doing that might destroy your system (not physically). It's the main process, which opens other processes when you start your system. The scvchost.exe-file is infected if it causes viruses. It should be replaced with a clean one, which could be done by reinstalling your operating system. There might also be a program that could repair the file. Blocking the svchost.exe isn't good either and if you attempt to stop it from the task manager it will send a pop-up with a timer. Then the countdown begins and the system will close in 60 seconds.

I moved svchost.exe to the recycle bin. Now my system is not working properly, for instance I can't copy&paste or run a search. What do I do? Please help!!!!

Do not remove lsass.exe and svchost.exe!! these isn't virus!! it must be infected by a virus!! if you exclude this files the system will not work right!! try to heal the file with an antivirus or replace with a clean file!!

I had a virus in my computer. I instalalled a new virus scan nod32 which detected the virus and deleted a lot of them, togather with this i guess it deleted SVCHOST.EXE. NOw when I startup my compute. I get a message stating svchost.exe not detected.
I can't open my taskmanager also, which probably could be because of this.
I would like to know how can I Install an svchost.exe from and how can I get My task manager functiong

i cant seem to shut down my computer the usual way..instead i am required to open my task manager every time, end task ISASS. exe before i could turn it off... i believe it is infected by a virus or something...how can i resolve this?..please help.

Hi Leo, I have deleted lsass.exe & smss.exe after my laptop infected with Funny IST scandal from the registry. I was not aware that these are windows files and essential for system to run. Now I am not able to boot my laptop, is there any solution for this?

Thanks in advance.
Rajesh.
