Most common type of virus disable the windows capability to show hidden files. To check whether the computer does not have virus , goto My Computer > Tools (Tab) > Folder Options > View >

Select "Show Hidden Files and Folders"

Click apply and ok

Again repeat the same procedure and check whether the selected "Show hidden files and folders" is still active or its been return to the "Don't show hidden files and folders".

If its still active then it means virus has not effected the system of at least you could delete the hidden virus files.

If it automatically return to the "Don't show...", virus has effected you system. Then go for a good anti-virus software.
