I don't want a free tiral version. It must be completely free, no money to buy it for it to work, cleans everything immediately and not just a few things then it asks you to buy it, and something that will work with Windows Vista Home Premium. I'm having major problems and can't seem to find anything to help me clean up my pc. I'm not computer stupid but I am computer smart enough to know if I don't find something, I'm gonna be up shits creek. Can anyone helps me out? Do you have something that works? Can you tell me where to go and I don't mean to hell lol!

I've read quite a few articles on registry cleaners and some say they are safe but others say the opposite.
So are registry cleaners really safe?
Thanks guys.
Y!Answers always gives me answers to computer stuffs =3

im just looking for cleaners to protect me from all sorts of stuff i would rather free stuff but if its heaps good i would like to know
i have trend micro and avast and cccleaner i did have AVG but i think thats is a waste all it does is just donwload updates and never finds stuff best free virus cleaner is avast trend micro is ok but it hasent piked up any viruses yet which is a bit sus ??? and i heard norton when it runs out puts viruses on your computer ???

I recently was experiencing a lot of pop-ups so I decided to download a different virus protection called "avast". But stupid me, I forgot to uninstall my old virus protection software(Norton) and now my computer automatically turned off the virus protection. I'm not sure what to do? Is there a way to turn it back on? Do I have to uninstall 'avast'?
If I need to uninstall norton, how do i do it?

More and more when I try to connect to the internet I keep getting pop-up's that there are fatal error's in my registry from all types of places such as fixmyregistry.com, www.windowsregistrycleaner.com. I don't have a credit card so what is the best safe freeware or shareware? Should I pay attention to these pop_ups? Everytime they come up they keep me from connecting to the internet and force me to use ctr+alt+del to restart my computer because I cannot access my start menu (the little hour glass shows when I go to it) HELP!
