Because several readers reveal their computer responding slowly, I am posting a summary checklist of general things you can do to solve the Errorbadfunctiontableproblem, and briefly discussing the three most frequent causes : malware, uncontrolled applications, and lack of maintenance.
Maybe the greatest contributor to a poorly performing computer is malware. Generally this is related to downloading an application that includes spyware, by not having browser security options large enough, by carelessly downloading P2P files, or by declining to install security sections regularly.
Stage 1. Update the definitions of your anti-virus and run a complete scan of your drive in Safe Mode. Resolve any unfixable issues. Notice that some viruses require extra steps before they may be removed; typically a websearch will locate specific directions or a special removal tool. Use the BC forums to request help, if you can’t find a solution.
Step 2. You have recently downloaded an application, and if the sluggishness is unanticipated, the issue might rest there. Test this by entirely eliminating it. A user will generally perform a internet search about the application before getting because in most cases, any possible trouble with malware or inferior performance will have surfaced.
Stage 3. Adware and Spyware can dramatically impact your personal computer’s functionality, and these are throughout the Internet. A very recent study showed that one out of every 20 executable files on Web sites is spyware, and 1 in 25 domains feature at least one bit of spyware waiting for sufferers.
Update the explanations of your antispyware applications and scan your hard drives in Safe Mode. Seasoned users will routinely operate two or three of these programs, because each company has its own requirements for what constitutes spyware and will just search against their own established. (A list of very great, free antispyware applications is supplied by BC). Again, solve any open issues before continuing to the next phase.
Stage 4. Evaluation programs that self-launching on startup. You pc may become a battleground for your attention. Many programs, for instance, install a fast-launch feature that permits them to be exposed rapidly; other programs may comprise an automated update feature that demands them to be operating in the background. Each of these slows down your launch Windows and each needs a small bit of resources while your computer is running.
The simplest approach to review and than to handle start-ups will be to use one of the many small resources available (see the Bc list of free programs). If, for instance, you have Spybot Search and Destroy, you can use its startup tool that lists startups and lets you to turn off any you do not need. If you are unsure about what can be safely deleted, remember that BC maintains a really complete Startup Database that includes info about whether the inquired item is required, elective, or unnecessary.
At-the same time, remember that all those icons in your Desktop also take a small amount of boot time to place themselves.
Lack of Care
Stage 5. Delete unused applications and exchange old files to a CD. Unplayed games, tons of family pictures, zipped files that you have already opened, applications you have not used in two years, software for that old printer you threw away last year—these are a few types of files you can delete.
(Note for advanced users: some professionals would comprise the additional upkeep step of cleaning the Windows registry, and you’ll find several apps to assist do that. For the most part, registry maintenance won’t make a significant difference, and unless you are quite comfortable with Windows, and carefully make copies of-the registry, you can do significant damage by making registry changes, so this measure isn’t contained
Action 6. Run scandisk / checkdisk in Safe Mode. Have it fix Errorbadfunctiontable.
Stage 7. Defragment your computer.
Hopefully, since you have have finished, you will see a noticeable improvement in pc functionality.
