Where can i get a free trial of a registry cleaner as my partners computer has 100% cpu usgae and badly needs a registry clean. usually when you download something it scans then says you have to pay for it to properly clean.

Ho know a sitte where i can find software free trial-WINDOWS REPAIR,OR OPTIMIZE and in the same time improve the performance of PC? ??for windows vista

Not only that, I need Virus Protection, anti spy, and firewall. I've been using the suite that is included with ATT Yahoo DSL but I need a different one because I purchased a new computer with Vista and they dont support Vista (and won't until at least August). Preinstalled on my computer I have a free trial of Norton but I was not happy with them on my last computer because I felt they take up too much memory. Give me some suggestions and why. I need the works but they don't have to be from the same provider. I was leaning toward computer associates but tell me what you think.

I just got a new laptop which came with a free trial of anti-virus protection. I already purchased virus protection from another company when I had my old laptop. Do I need to uninstall the free anti-virus program before I install the virus protection I own. If yes, how would I uninstall it.
