Computer protection????????

I’m building a computer. I’m spending a lot of money on it. I want to know ALL protection needed to keep my computer clean and healthy.

What is the best program for the following? (Preferably NOT free)

Anti-Virus
Anti-Spyware/Malware/Adware
Disk Defragmenter
Registry Cleaner
Disk Cleanup

And if I missed any other cleaning/health program, please specify!
And I don’t necessarily mean one program for all.

Geek Squad Repair issues?

A year ago, my daughter saved her own money to but a lap top computer.
We bought it, and an extended service contract from Best Buys.

It proved to be a lemon, and after several repairs (motherboard, hard drive, etc) they replaced it with another computer of a different make.

I paid for another extended contract…but when this machine had issues, they are trying to pawn it off on "software problems"—not covered and want to charge nearly 200 bucks to fix it.

Everyone who’s heard of the problem think the issue is power/ hardware related. While we were waiting to have the puter serviced, every customer was told the same thing "If the issue is spyware, it’s not covered…"

I think they are simply trying to weasel out of the contract, and "software" is just an excuse. Has anyone else had a similar experience with Geek Squad? It also took them 11 days to run a simple diagnostic. That’s absurd. So is paying 25 percent of the price of a product not even a year old.
My daughter says the screen goes black at random. She also said that re-booting doesn’t always bring it back.

She has a Toshiba laptop, and twice in the last year we had to replace the power cord. The first one used to get so hot it could almost burn your skin, but the latest doesn’t do that.

We use Avast and Ad Aware for anti-virus.

This doesn’t sound like any virus I have ever heard of. Opinions?
Even worse…when we retrieved the laptop, they tried to get me to sign a form that said it "had been repaired to my satisfaction.

THEN we found two new icons on the computer, one for a direct internet connection none of us had ever used, or heard, and the other for files equal odd.

Wonder what the boys do on their breaks?

BSOD: Copied over /repair/software and now can’t login!?
My work computer recently stopped working. When I boot it up, it gives me blue screen with hive message can’t find system32\config\system. I went into recovery console but it wanted admin password which I don’t have and corporate won’t give me. I don’t want to send it in and wait to get it back, so I hooked up hdd to a desktop and copied c:\windows\repair\software to c:\windows\system32\config\sof… Put hdd back into laptop and booted up and it boots into windows! However, it doesn’t recognize my username/password anymore. What can I do to fix this?

Thanks!
i’m not hacking it; i’m simply fixing it like i would if it were mine, but now my username/pw no longer works; i’m in IT, but i’ve never run into this problem before; they can’t give me the admin pw because it’s the same for the entire company, but i can fix it on my own to save the company a lot of money; and i’ve made backups so everything i do is reversible; i simply need this to work so I can do my job
Well this is the answer I get? And from a "top contributor" at that.

I have a virus on my computer that is mainly located in this Loaction…HKCU\Software\Microsoft\Windows\CurrentVersion\InternetSettings\ZoneMap\EscDomains. I have no idea what HKCU is and where to look for it to manually remove the files attached to this trojan. I do not have the money to pay for software or even worse a PC repair shop so I’d like to manually delete.

I have an older Dell Latitude & I have been having a lot of problems with it. I have WipeDrive v5, but I’m worried if I run this I will lose Windows XP. I can’t find my Windows software either. I don’t understand how these programs work, but I’m tired of my computer running slow, having network problems, etc. I’ve upgraded the memory, and there’s more than plenty available for processes. I have to use a wireless card, which is new, and I know my router/signal is fine, because my other laptop works fine. Also, there’s 2 diagonal lines of keys on my keyboard that don’t type the letters & my mouse likes to go up to the corner of the screen & when I try to move it back down, it takes off away from me again. I need some computer advice, please! I don’t have money to take it for repairs, but I don’t want to make it any worse.
