the ALCMTR.exe which is for my 5.1 realtek sound card so i shouldnt get rid of that, right?
Sorry, I normally include a little description for this file, but I left it out. ALCMTR is related to Realtek, but it is not a necessary file. In fact, it is considered by many to be spyware. It's not malicious, but it does track certain activities and send the information back to Realtek. I suggest removing it, but you don't have to.
and ive got an idea but what exactly will hijackthis do when i hit the "Fixed Checked" button?
im just a little curious
Good question. Basically, when you click on Fix Checked, HijackThis edits the registry entry and disables it. It doesn't delete files (although the prompt makes it sound otherwise) and it doesn't always even delete the registry entries. It pretty much just switches them off so the related file(s) won't run next time you boot your computer.
plus why exactly do i need the CCleaner and what does that do??
CCleaner cleans out all of your Temp and Temporary Internet Files. It deletes other things too (unless you tell it not to), but those are the two main concerns for me. Also, with the Issues feature, you can find and remove a lot of rogue/obsolete registry entries. It just helps out with cleaning things up a bit. And don't worry, it's perfectly safe and won't delete any important files. Use it a bit and I think you'll decide to keep it.
