Regarding: When i go to download avast or any virus scanner


What antivirus program has been protecting this computer?

Regarding: LWS.exe ,hp monitor21.exe, and Reader_sl.exe always come up


From Start> Run (or Windows logo key  +r) type in msconfig then hit Enter. On the msconfig Startup tab, if sl.exe or Adobe Reader sl.exe is listed, uncheck it. Do the same with  HP Monitor21.exe then OK your way out.


Lws.exe is software for the Logitech webcam. If you have the disk that came with this webcam, uninstall the webcam from Control Panel> Add or Remove Programs and reinstall it from the disk. If you don't have a disk, search for a driver/software for  the specific model at

If you don't use the webcam, you can uncheck it from msconfig> Startup and the error message should stop.
