How to clean all malware and speed up the computer?

I am needing help fix my neighbors computer,


I need to remove all their malware and speed up their computer system.


Is there a step by step guide I could use than can help me out?


And software to diagnose issues and telling me what to do to fix them.





They have 5 pc's


Running:


windows 2 w xp 2 w vista and 1 w 7 please help|||Use a trial version of Revo Uninstaller in aggressive mode to remove all of the programs you do not use, especially the bloat ware that may have been installed when the computer was new. Unlike windows uninstaller which is mediocre at best Revo removes orphan files and registry entries that are left behind. Take your time. It is a little confusing to understand because things are laid out differently. When the window comes up that shows the registry items it only removes the items in bold. There has been no problem with selecting all, then delete.





Although it is said that items left in the registry do not slow the computer I prefer to keep mine clean. CCleaner is an excellent product. Take your time. You can always go back and delete an entry later if desired.





Run either Revo or Ccleaner to find orphan files on your hard drive.





Go to windows Disk Cleaner. For System Restore check to clean the files. This will remove all of the restore points prior to the last one. You can also remove other items suggested by the cleanup app.





Windows disk defragmenter does a fair job. Perfect Disk does an excellent job. Download the trial version. Allow it to run in Smart mode so the file location is maximized.





Not all antivirus programs will catch everything. Download Malwarebytes, Avira and Avast. Run these one after the other to find all traces of a virus, spyware, hijackers, keyloggers, etc. Do not have more than one antivirus on the computer as it can cause serious problems.





Programs like to load themselves in the system tray. They do not need to be running at startup. Go to Start/Rum. Type msconfig. Go to to the Start tab. Look for programs than do not need to run at startup especially printers and automatic updaters. Use Google to find the meaning of the file names. If a location for the file or file name is not shown uncheck it as it is bad news. Check OK, then reboot. When back in windows the System Utility will open. Click the box that says not to run at startup.





There are more items that can be shut down under Services but do not try this without full knowledge of what is being done as the consequences can be serious.





Keep up with the above mentioned disk maintenance to keep the computer running at its best.





It is normal for the computer to run a little rough for a few days and through a few reboots. There has been a lot changed and the system needs some time to get itself organized again. Once you are completed with the maintenance and the system is working smoothly create a restore point with System Restore. This just lets you know it was at a good status when the point was stored in case a Restore is needed.|||It is not so well to format your neighbors computer,as it will lost somethingg important and useful.

Malwarebytes Antimalware is very good, but it is best to boot into Safe Mode with Networking, download and run Rkill from www.bleepingcomputer.com followed by a fresh download and run of Malwarebytes. This avoids the problem of the downloaded file itself being infected before you can use it.|||easiest way : format all!
