Im trying to delete unnecessary programs like the computer is slow, but might have deleted something important as email yahoo virus checker suddenly does not work

How can I know if the programs listed in Add/Remove programs are essential or not? Some seem obvious, but there are others who are not. I tried to cross and remove what I use not but theres so much I don't know what they are doing and if I really need things telling not used since 2005 or what are sometimes programs that I use.
I also clicked on a button in the list, instead of asking me if I wanted to remove or change as usual, he took something and I don't know what it was. Can I know what I deleted?
Thank you.

clairecat,
You can search through the event viewer to see the items you deleted.  If you're just going through your add/remove program list and want to know if you need the program, then I watch the last time that it has been used and then get on the internet if you do not know what the program does.  The link below gives some good tips to keep your system works well.
