heres the deal:
when a computer gets a virus, it can get into many places. one of which maybe the directory root. windows, throughout its history as an os/addon (another story ) created a space block on the hard drive, upon installation of itself. in this directory, there are spaces for pointers, which point to the location on the hard drive of a file/executable you may wish to access/run. this virus may have filled up a space in this directory, and then in the registry to startup this exe everytime windows starts up.
you can go into the registry to find it. using xp, start-run-type “regedit”
you can then press control-f or use the edit menu and click on find.
type what you are looking for, llase.exe i think you posted, and if it finds any keys ( registry entries are called keys ), delete them, and a message box will showup asking if you are sure. hit yes.
note, if you want to be “safe”, i suggest exporting the registry to a file:
file menu-export-click option at bottom of dialog box “export range” to “all”-type in a filename-save
this way, for any reason, if you delete a key a program needs ( besides the llase.exe program ) you can “rebuild” the registry by importing the saved registry to try again:
file menu-import-locate the saved exported registry file-and click import.
or you can use a third party registry cleaner, of which i cant point you to one that will be suitable for your needs, as i just use the registry editor from windows.
