Hi every body:
i was told that there's a way to clean your computer from malicious files and you can perform that without using any program or anti-virus,and better with just a click.
---------------
go to start/run and type this mrt /f and press OK.
i've tried my self.
Mrt is Microsoft's Malicius Removal Tool. It already runs automatically on every Windows XP and above when you enabled automatic updates (although /f does a more extended check than the automatic run). However, MRT is not a replacement for a virus scaner. MRT will only look for a very limited set of common threats, it will not scan for many thousands of viruses like a real scanner. Also mrt will not provide any kind of protection at all. you can only use it after you are already infected.
yeah i prefer ccleaner too
Yeah pals i'm ok that Ccleaner is great for that purpose,but i believe that the threat here is "cleaning your computer WITHOUT any program",you can make the most of your Os before seeking out of further help such as ccleaner or tunup utilities

well i don't know if that's what your looking for but maybe disk defragmenter could help you. you can find it in:
Start menu --> All programs --> Accessoires --> System Tools --> Disk Defragmenter
take a look at it

Thnx a lot iKingsten,the MRT is doing great,for scanning of course

anytime

it'll speed up your computer, i suggest you to use it for all your harddrives

Yes, CCleaner is a freeware system optimization, privacy and cleaning tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. Additionally it contains a fully featured registry cleaner. But the best part is that it's fast (normally taking less than a second to run) and contains NO Spyware or Adware!
