If you stumbled across this article from a search start by reading how to fix a slow computer Part 1 before going any further.
The next process in fixing a slow computer is to get rid of all the spyware and or viruses on the system. First you will need reliable software for this exercise. I would advise getting rid of any virus or spyware software that you have installed that you didn’t pay for. Free software is generally ok, but, you get what you pay for. I personally like to know I am protected while surfing the Internet for example. Just landing on a web page through a Google search can get you into a whole lot of hurt. Many web sites are corrupted and install a virus or spyware application as soon as you land on them. There are only a few companies at the present that offer hourly updates on virus database files. I would also suggest purchasing a spyware remover application.
For that reason download and install ESET NOD32 - fast, effective, and lightweight antiviral software – save 25% on a 2-year subscription Eset has hourly updates to guard you against virus attacks. The software is easy to use and isn’t considered a memory hog like Norton Anti Virus. ESET pioneered and continues to lead the industry in proactive threat detection. ESET NOD32 Antivirus, consistently achieves the highest accolades in many types of comparative testing. NOD32 is the foundation of their newest product, ESET Smart Security, which provides antivirus, antispyware, antispam and a personal firewall. Both solutions stand apart from the competition in that they combine accuracy and speed with an extremely small system footprint, which translates to powerful protection that won't slow down your computer. After downloading and installing Eset Anti Virus I would highly suggest removing your previous Anti Virus software as they will fight with each other. To remove your old virus software go back into control panel and remove it from the add remove software option or the programs and features option.
A good and trustworthy spyware application that I like to use is Spyware Doctor. Spyware Doctor is a top-rated malware & spyware removal utility that detects, removes and protects your PC from thousands of potential spyware, adware, trojans, keyloggers, spybots and tracking threats. After downloading and installing Spyware Doctor please remove any other spyware software you have.
Now that we have these wonderful applications let’s put them to good use. Restart your computer in safe mode. Read this article if you are not sure how to enter safe mode.
Now that we are loaded into safe mode launch Eset NOD32 Anti Virus and start a full system scan. Launch Spyware Doctor and perform a full system scan. After the scans are finished remove all the little nasty objects they found. When you are finished scanning restart your computer into regular mode. To do this just restart your computer.
Now that our system is running clean again I would advise creating another restore point as we discussed in part 1 of how to fix a slow computer.
The next thing we should do is optimize our registry. I use a program called Registry Mechanic to do this. Registry Mechanic is an advanced registry cleaner for Windows that can safely clean, repair and optimize your registry in a few simple mouse clicks!
We are almost done, but first since we deleted so many files from our hard drive we should check the drive for errors and then defrag it. To check the hard drive for errors we launch the check disk utility supplied with windows. To do this do the following: Hold down the windows logo key on your keyboard and then press the R key. When the run box loads type in cmd and then press enter on the keyboard. When the black DOS box appears type in chkdsk /r It may take a while for the utility to go through the process, when the process finishes it will advise you of what it found. If the utility found bad blocks on your hard drive I would advise replacing your hard drive.
Finally the last procedure in making a slow computer faster is by defragging the hard drive. For Windows XP users do the following: Click Start | Click My Computer | Right click C:\ and choose Properties | Click Tools | select Defragment Now | then choose Defragment.
For Windows Vista users please do the following: Click Start | Click Computer | Right click C:\ and choose Properties | Click Tools | Click Defragment Now | then click Defragment Now again.
That is it, you are all done. Hope you enjoyed the article. If you enjoyed this article you may also like to read up on Computer Maintenance.
