I caught a virus on my laptop(thanks to my lil brother). I have a sony vaio with 2gb memory running windows xp media edition. I cleaned the registry(have done it once before with no problems to get rid of a virus). computer starts with blank screen and takes about 30 minutes to load icons. Cant click on icons or start any programs. Do i need to reinstall the OS or is there a way to fix this?

Hello Everyone,
In the last 2-3 months, I have been installing and uninstall some software from the internet, things like Tortorrent download tools, software tools, Eclipse, NetBeans, Quick timer, iTunes.. etc.. a lot of them. Then after using them, I have uninstalled a few cuz I realized I no more need them. Now my Pc is running very slow. Also I faced a problem where this ccsvhost.exe (Norton related) stuff would eat up all the memory and cpu, I just found a work around I open up norton then disabled few kind of scans like messanger and such stuff or background scan, that helped me from norton slowing down the system. Having done all this good lot of crap.. Now I am feeling I need to clean up my registry. I understand that I am trying to install one more tool, but any tool that is worth installing and that might clean up my registry, without bothering me to buy the software in the middle of its job? I mean it totally annoys when it says so many issues are identified with your registry, but plz subscribe for it to further clean up :(. .. It will be a great help if anyone of you help me with this.
Thank you in advance.
Hi all, Thanks to you all for the reply.

I just used Advance System Care free ware, so far so good, I will see for a day or two and if it looks fine then shall update again with the observations and then try the suggestions by other guys.

After pressing F8 to accept the Microsoft agreement it brings you to the partition page that displays your hard drives and partition. The problem is that nothing shows up here for me to do anything. I’ve tested the hard drive and memory. I’ve also tried swapping drives to see what would happen, but same thing. Any advice would help, thanks everyone.

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.

im trying to delete junk from hard drive whats the easiest and best way to do that? also… does overloading on memory restart the computer?? i inserted an extra 250 mb of memory on the 500 that it has already…..how can i check this out…??
but i dont have or i lost the windows xp cd… any other way???
