How do I easily delete all unwanted host files from my computer?

Not being an IT 'wizard', it appears that these files are automatically downloaded whenever I surf the net and subsequently permit the sender to communicate with my computer, record my surfing/visits etc.

I have set my options to automatically delete all internet history and I want to restrict the 'host file' registry to ONLY those programs I have installed.

Can this be done, easily, and safely?

i geuss u need to do some other stuff to be sure that ur compuer runs like new , clean and fast

follow that ::--

1.CLEAN YOUR TEMPORARY FILES AND OBSOLETE REGISTRY ENTRIES REGULARLY. how ?? --->

Download CCleaner and run it’s Cleaner section, once daily, before shutting down your computer.

It removes all the trash files that are created while surfing through the net. Use its Issues

section once a while to delete all the unused registry keys. Another good cleaner, Disk Cleaner,

can be used along with CCleaner for even better results.

2.REMOVE ALL THE UNWANTED AUTO-START ENTRIES. MOST IMPORTANT PART

If you have a lot of Auto Start entries, then you should remove them. To do so, go to Start > Run.

Type 'msconfig' in the box and then click 'Startup' tab. Uncheck anything that is unnecessary.

Of course, you can revert that in future. Just go back to MSConfig and check anything back that

you removed from the start-up list. However, you should not remove any of the security related

startups (read next point), like the real-time shields of your anti-virus / anti-spyware, firewall etc.

3.KEEP YOUR COMPUTER SAFE AND GET RID OF VIRUSES AND ALL OTHER FORMS OF MALWARE.

Any Windows computer connected to the Internet MUST have an anti-virus, a firewall and and one or two anti-spyware.

They MUST be regularly kept updated with the latest detection databases. The real-time monitoring of the anti-virus

and any one of the anti-spyware should always remain active .

I give u some free and good anti-virus, anti-spyware and firewall, you can get them get them all:

> Anti-virus: AVG

> Anti-spyware: Spyware Terminator , a-squared Free

> Firewall:Comodo Personal Firewall

N.B. Never keep two anti-virus or firewall on a single system. If you are already using a good anti-virus

or firewall, then you need not download the corresponding one. You can, however, use as many anti-spywares

as you want, provided you use the real-time protection shield of only one of these.

4.ALWAYS MINIMISE THE USAGE OF RAM.(Only for those with 256MB or less RAM)

For this purpose, you may keep a virtual memory booster as an auto-start entry. It frees the clogged RAM.

I use RAM Booster, which is very effective. Here is the link to download it:

http://www.download.com/rambooster/3000-...

To configure it, please follow these steps:

* Click on Edit > Options and tick the follow options:

(a) Set auto optimisation on

(b) Show CPU usage

(c) Start minimised

(d) Launch automatically at start up

Also, change the ‘Auto Optimisation Level’ and 'MB of RAM to free at auto level' as per your requirement.

5.DON'T JAM YOUR MOTHER DRIVE (C:).

Keep at least 35% of your C: free. Transfer all the music, image and video files to other drives.

6.DEFRAGMENT THE HARD DRIVES PERIODICALLY.

Defragment the hard drives (especially C:) once every month. To defrag, go to Start > All Programs > Accessories > System Tools >

Defragment. It takes a lot of time (50 minutes or over) so don’t become impatient. It’s for your computer’s good.

7.You may get the free Google Web Accelerator to boost up your Internet speed http://webaccelerator.google.com/

8.ALWAYS KEEP YOUR RECYCLE BIN EMPTY.

-.USE MINIMUM POSSIBLE SHORTCUTS ON YOUR DESKTOP.

9.IF YOU HAVE GENUINE WINDOWS, KEEP IT UPDATED EVERY MONTH. IT HELPS A LOT BY FIXING MANY VULNERABLE SECURITY ISSUES

10.HEAVY GAMES CAN PUT A LOT OF PRESSURE ON VIRTUAL MEMORY. SO, STAY AWAY FROM THEM IF YOU HAVE 512MB OR LESS RAM.

11.SET YOUR WALLPAPER TO BLANK.

You will hate this suggestion, but believe me; blank wallpaper helps a faster startup.

Note :- when u run antispyware or antivirus run it in safe mode

how --->To do so, go to Start > Run Type 'msconfig' in the box choose diagnostic from the general tabe and retart ur computer run the antispyware and do not forget to do all over again but choose normal instead of diagnostc

you will neeed a windows utility wizard called

ccleaner

download it from

http://rudebox.editboard.com/How-To-Windows-f25/How-To-Windows-Utilities-f29/How-To-Do-DiskClean-Up-Uninstall-Files-Repair-Registry-t89.htm

and press the run button (to clean ) when installed

you will see an alert just click ok and it will clean all unwanted things from ur computer
