Maybe the most important factor to a poorly performing computer is malware. Usually this is related to downloading a software that contains spyware, by not having browser security settings large enough, by carelessly downloading P2P files, or by failing to install security areas regularly.
Step 1. Update the definitions of your anti virus and run a full scan of your hard disk drive in Safe Mode. Solve any unfixable problems. Note that some infections need additional steps before they may be removed; normally a web search will find specific instructions or a special removal tool. If you fail to find a solution, use the BC forums to obtain help.
Step Two. If the slowness is unanticipated, and you have recently saved an application, the problem might live there. Check this by fully removing it. A user will typically perform a websearch about the program before installing because in most instances, any possible difficulty with malware or inferior performance will have surfaced.
Stage three. Adware and Spyware can radically effect your computer’s functionality, and these are around the World wide web.
Update the explanations of your anti-spyware programs and check your hard drives in Safe Mode. Experienced users will regularly run several of the programs, because each company has its own requirements for what constitutes spyware and will just search against their own established. (A set of very great, free anti-spyware applications is provided by BC). Again, resolve any open issues before proceeding to the next step.
For further reading about Malicious software and some malware removal applications, use BC’s Tutorial section; most of the applications have quite good Help documents that explain how they function as well as the unique features of each.
Stage 4. Evaluation applications that self-start on startup. You computer can become a arena for your consideration. Many programs, for instance, install a rapid-launch feature which allows them to be exposed fast; other programs will include an automated update feature that requires them to be running in the background. Your launching Windows are slowed down by each of these and each requires a little bit of sources while your personal computer is running.
The simplest approach to examine and than to handle start ups is to utilize one of many small utilities available (see the BC list of free applications). You can use its startup tool that lists startups and allows you to turn off any you do not want, if, like, you have Spybot Search and Destroy. Remember that BC maintains a very comprehensive Startup Database that contains information about whether the questioned item is required, optional, or unnecessary, if you are uncertain about what may be safely removed.
At the same time, remember that all those symbols in your Background also take a small number of boot time to place themselves.
Lack of Upkeep
Step 5. Clean up your hard drive (preparation for Action 7). Delete unused programs and move old files to your CD. Unplayed games, lots of family images, zipped files which you have previously opened, applications you have not used in two years, software for the old printer you put away last year—these are a few types of files you can delete. Then use Window’s Disk Clean-up to delete temporary internet files, temporary PC health files, etc.
(Note for higher level users: some specialists would contain the added maintenance stage of cleaning the Windows registry, and there are plenty of apps to help try this. For the most part, registry maintenance will not make a major difference, and unless you’re quite comfy with Windows, and carefully make backups of the registry, you can do serious damage by creating registry changes, so this step isn’t contained
Action 6. Run scandisk / checkdisk in Safe Mode. Have it fix The specified domain either does not exist or could not be contacted..
Action 7. Defragment your computer. Windows will set new files in any available open space; defragging will set associated sections of files closer together so your read arm has less going around the hdd to do, saving wear-and tear while boosting up programs.
Hopefully, since you have have ended, you will find a noticeable improvement in pc functionality.
