Start Cleaning :


To disinfect your system you need a good antivirus software. i prefer avast, because it has nice scan features, antivirus, anti-spam, and also anti-root protections- all these are in a free version. Also it has a great feature that is boot-time scan. that means it can scan a pc before it loads operating system.

So first download & install the avast anti-virus from the www.avast.com/free-antivirus-download

after install the avast, set the boot-time scan first.

to set that open avast by double click on the avast icon in the system tray.

click on the scan computer.

select boot-time scan and click on "Schedule now" button.

now restart the system. after boot animation complete [ XP & Windows7], a screen appers like this

now avast will perform a full system scan, when a virus is detect it will ask what action action to take like this

press '1' to delete the file

press '2' to delete all the infected files

you can also move or repair the infected files. plese note that repairing a infected file is not possible in all situations. if you the file is not infected you can ignore it by pressing '7'.

after complete the scan the computer will starts normally. 

Congrats....!

now your system is disinfected. 

note: if your system is fully infected including core operating system files, which are required to start the system 

these are also removed, so be-careful. first back-up all the required data in the my-documents,  desktop, and c drive before starting the boot time scan.
