I had installed a speed up utility on my pc. I got a popup that my pc is working extremely slow. So I installed a tune up software to improve the speed. But that did nothing. Instead of making it faster my system is now much more slower. I am getting a a huge list of bufferchm in add remove program. I removed them and restarted the pc but it appears back again. I think this is some kind of virus. How to completely get rid of it.
