my computer is very slow since yesterday ,what can I do?

Answer 1

Do an anti-virus scan. Delete temporary internet files.

Answer 2

The best way is to download Ccleaner here http://bitly.com/UrALrK

Or you can go on Windows operating system locate the command prompt and go there to do the following:
Create a Recovery file of system and date it today.

Then begin by;
delete the 'Temp' folders..they have hidden subfolders so you need to set the attributes in order to bypass this. For each subfolder delete all cookies and rubbish left behnd after install-uninstalled programs. Do a 'dir' command to check your progress. Make sure the 'Temp' file is empty.

goto c:\windows\prefetch and delete everything in there..no exceptions

goto c:\windows folder and delete all the '$' files that have been installed by updates. They can all be succesfully deleted and just take up disk space.

Locate the Internet Temporary Files..Check to see how high the saving level is..some have it set at 30 days..but that stores faaaar tooo much data..though it slows down the system overal. Keep this to a minimum..suggest 2 or 5 at most.

Delete all 'cookies' all those you don't need.

Locate the windows directory and go through the folders you know and those you don't need. Check this once a week at least. Some programs will install under XP as NT and older systems where there is no check of systems weight.

Check to see that system files have not changed since last booting. Things like .ini files or .bat are important items.


Check for 'Hidden Directories' all over the disk...do this at the command prompt:

dir *.* /ah wil show these hidden directories

Check the 'dir' command for all parameters

Answer 3

There is no harm in doing a good clean out of temp internet files, cookies ...doing a defrag etc etc etc. But I would recommend that you have asked this question too early...computers have a habit of going slow for no apparent reason & then for no apparent reason start working fast again..Obviously there is a cause for this but there is often little point in trying to find out why when it's going to clear up in a day or two...so leave it 2-3 days then start thinking about there maybe a problem you need to address.

Answer 4

Could be a virus has crept in, or you have installed something that is taking up a lot of CPU time.

First run a virus scan.

Then check in the taskbar what is running, such as a defrag program, or even a background virus checker.

If you are happy there is nothing there, and you do not have a virus, have a look in the Task manager if something is getting loaded, but not shown. You can goggle any of the application names to see what they are.

Hope this gets you started in the right direction.

Answer 5

I'd suggest you install and run Ewido anti trojan and Ad-Aware SE Personal in Safe Mode. If your computer suddenl;y started to run slow you probably have a trojan. Then reboot and run Ccleaner.
Turn off System Restore by going to Start - programs - accessories - system restore.
To get into safe mode, repeatedly press the F8 key after the bios screen loads but before Windows loads, if you don't manage it first time just restart and try again.
Safe mode looks very different and not all your programs will load but don't worry, its supposed to do that. The screen will run at 800 x 600. The scans will take a bit longer so just leave it to get on


The Windows firewall doesn't stop malware on your pc from dialling out. Either of these firewalls are free for personal use and stop unwanted incoming and outgoing traffic. You choose which programs are allowed to access the internet. They are both fairly easy to use and updated regularly.
