My computer runs slow and after a scan by Norton found these two that the anti-virus can’t get rid of. How do I get rid of them. Is there a special download that will do it?

Everytime i install a program into my computer my computer becomes very slow in bootup. When it boots up the explorer appears but the system tray programs arent in place. I dont have that much programs in bootup all i have is my firewall and my antivirus that boots up and this hasnt become a problem before i installed a program. The program isnt a virus and i have enough ram (512 mb). my firewall is zone alarm and i use AVG anti virus Free. it takes about an hour or 2 juss to boot up my whole computer and i checked msconfig already to check if there are any startup problems. I checked regiestery problems with CCleaner and i defraged my harddrives yet it still wont work. There are no spyware on my computer i scanned for viruses. Can anyone help?

For some reason my computer is been freezing lately, wow is lagging like crazy and counter strike just froze after a while of playing. I tried many Registry cleaners, scan my computer for virus, spyware, malware.I have defrag my computer, update everything. I checked over heating and dust seems fine plus i put my fan at its fastest pace so it wont over heat. This started to happen like a week ago. Here a list of software I use to scaning for anything.I think is hardware failure or something to do with my power supply.
Zone Alarm Extreme security my firewall/ anti virus/ anti spyware
Advance system care pro Registry cleaner/anti spyware/cleaner
Malwarebytes anti malware

Roughly how much would it cost for a small business to get the following done to their HP laptops by a computer repair firm (11 HP laptops):

-reformat HDDs
-install windows XP
-install adobe acrobat
-install an anti-virus programme
-install MS office
-run a full diagnostic
-clean the exterior of the PCs

how much would it cost, excluding any transportation costs, and costs of buying the software?
what would be the average cost? is per PC (0 total) a good deal for buyer and seller?
i know i could do all this by myself…i am doing it for someone else…just wanted to make sure i was giving them a good deal, but not too good.

oh well, no such thing as too low of a price as long as we stay afloat.

I currently have Registry Patrol, but don’t think it works very well. What do you think is the BEST Registry Cleaner/Scanner?

Also what do you think is the best anti-virus and spyware software?
