My computer is affected by an viros. No anti-virus program couldn delete it. What should I do ?
U can boot Ubuntu live CD and click on "try Ubuntu without any changes' . Now check all the folders to find any suspicious files(eg. autorun virus and any suspicious .exe files) and delete them, especially system volume information (delete everything to be sure), recycler etc. Again, it is best if you have a partitioned disk( 2 or more) or 2 or more hard drives, clear everything in the 'system volume information' and 'recycler' in all the partitions and check all folders also. Now format the partition that contains the operating system and install a fresh one. After installation is completed. Do not open any file or program( or else u r doomed). the first u do is install a powerful Anti virus(eg Avast) , personally I use Avast Internet Security. Now Use Avast to scan all the other partitions to be sure and get rid of any virus u might have over looked (if u have more than 2 partitions).I do this B'cos strong viruses are not easily detected by Anti virus soft wares. U r done!!! It works for me every time( so I never lost any important data) NB i do not keep any of data on the system drive, only movies cos i will get them again from friends.

Running a clean up tool before you scan will also help
try malwarebytes or spybot search and destroy
I would like to suggest several programs which you can use.
The first of which is Spybot http://www.safer-networking.org/index2.html
Install it, update it, and run it. Once you run it, remove whatever it detects, and then remember to immunize your system.
Other programs you can use are malwarebytes and adaware. Links of which are http://www.lavasoft.com/ and http://www.malwarebytes.org/ .
They all offer free versions so you should be good to go.
Once all this is done, install a decent antivirus, such as AVG or Avast. If you hate those notifications anti viruses give, just install Avast and enable Gaming Mode.
