how to clean up infected PC

Musim Virus, musim hacked meng-hacked...
kadang kita terima email yang subjectya cukup mengundang penasaran , tapi pas diclick...euh siborokok teh Virus.....

Basically the steps are:
1. Get a blank CD or blank USB memory stick.
2. On a clean (or relatively clean) system, browse to:
http://connect.microsoft.com/systemsweeper
3. Click on Download 32 bit version
4. Run the exe that you just downloaded, it's: mssstool32.exe
5. Follow the instructions to create your bootable CD and/or USB
6. Put the cdrom into the infected system or plug in the USB.
Make sure the system is plugged into the internet.
7. Reboot your potentially infected system, but just after it turns
back on you must hit the f12 key. If you miss and wait too long,
it will start booting your OS, then kill the power and try again.
Eventually you will get a "boot menu". That boot menu will allow
you to boot from cdrom and/or usb. An older system might not have
usb booting. Select USB or CDROM depending on which you are using.
8. Wait for the sweeper application to come up (takes a while)
9. Run the scan. If "scan" is not clickable you may have too old a
version of windows ( good for Xp,vista or 7 Only)
10. When the scan is done it will tell you about the infection and
let you click a button to fix it.
