Because several readers write about their computer responding slowly, I am publishing a summary checklist of general things you can do to resolve the Unknown Application Downloadproblem, and briefly discussing the three most common causes : malware, uncontrolled applications, and insufficient maintenance.
Maybe the most important factor to a badly performing computer is malware.
Step 1. Revise the explanations of your anti virus and run a complete scan of your hard drive in Safe Mode. Resolve any unfixable problems. Note that some infections require extra measures until they could be removed; generally a websearch will locate specific directions or a particular removal tool. Use the Bc forums to request assistance, if you cannot find a answer.
Step Two. You have recently saved an application, and if the slowness is unanticipated, the issue may dwell there. Test this by fully removing it. A smart user will typically perform a internet search about the application before downloading it because in most cases, any potential difficulty with malware or inferior performance will have appeared.
Action 3. Adware and Spyware can dramatically impact your personal computer’s operation, and these are around the Internet.
Experienced customers will frequently operate several of these applications, because each company has its own criteria for what constitutes spyware and will simply search against their own established. (A list of quite good, free antispyware applications is given by BC). Again, solve any open issues before continuing to the next phase.
For additional reading about Malware and some malware removal applications, use BC’s Tutorial section; most of the applications have really great Help files that describe how they function also as the unique features of each.
Stage 4. Evaluation applications that self-launching on startup. You pc may become a arena for your interest. Many programs, for example, install a quick-launch feature that enables them to be opened fast; other programs may contain an automated update feature that demands them to be working in the background. Your launching Windows are slowed down by each of these and each requires a little bit of resources while your computer is running.
The simplest method to examine and than to manage start ups is to work with one of many little resources available (see the Bc list of free programs). Remember that Bc maintains a very complete Startup Database that contains information about whether the item is required, discretionary, or unnecessary, in case you are unsure about what can be safely removed.
At the same time, remember that all those symbols on your own Background also take a small number of trunk time to put themselves.
Lack of Care
Stage 5. Delete unused applications and move old files to your CD. Unplayed games, lots of family pictures, zipped files that you have previously opened, applications you haven’t used in two years, software for that old printer you threw away last year—these are a few examples of files you can delete. Then use Window’s Disk Cleanup to delete temporary internet files, temporary PC health files, etc.
(Note for higher level users: some specialists would include the added upkeep stage of cleaning the Windows registry, and you’ll find plenty of programs to assist do this. For the most part, registry maintenance will not make a major difference, and unless you are quite comfy with Windows, and carefully make backups of the registry, you can do serious damage by creating registry modifications, so this measure is not included
Action 6. Run scandisk / checkdisk in Safe Mode. Have it repair Unknown Application Download.
Step 7. Defragment your computer. Windows tends to put new documents in any available open space; defragging will place affiliated sections of files closer together therefore your read arm has less travelling around the hdd to do, saving wear-and tear while racing up plans.
Hopefully, now that you have have finished, you will see a noticeable improvement in computer functionality.
