Sooner or later, most of us notice that the speed of the computer has dropped significantly. Why is this happening? After all, the hardware part of the computer has not changed - the processor performs the same number of operations per second, the memory size remains the same, and, it would seem, the speed should not change. And this happens due to problems in the software part of the computer - viruses, erroneous registry keys, incorrectly removed programs. All this leads to a significant decrease in the speed of work.
It is necessary
In order to fix software errors, special cleaning programs are needed. It is convenient to use the already popular "HijackThis" programs to fix bugs and suspicious "holes" in the system,”Dr. web cure it”for getting rid of viruses and“Regcleaner”for cleaning the registry. All of these utilities are distributed under a freeware license, so you won't have any problems purchasing them - all of them can be downloaded openly on the Internet
Instructions
Step 1
First you need to get rid of the viruses. Disconnect your computer from the Internet, from the local network. Restart your computer to Safe Mode. Run the program”Dr. web cure it”and run a complete virus scan of your computer. This may take a long time, but it must be done. Remove any virus files found. Reboot your computer.
Step 2
Now let's clean up the registry. Run the "Regcleaner" utility. On the Software tab, mark the programs that are no longer in your system, but from which there are entries in the registry. Click "remove selected". This will get rid of unnecessary entries. Now let's search for registry errors. Click Tools - Registry cleanup - Do them all. A search for erroneous keys will start. Mark all errors with a checkmark and select "Remove selected".
Step 3
And finally, let's protect our system using the "HijackThis" utility. After starting the program, select the "Do a system scan only" item, and, as in the previous case, mark the errors and click "Fix cheked".
After carrying out such a cleaning, the speed of the computer will noticeably increase, and the security will increase.
