|OK, you're not very 'computer savvy', but we could do with a bit more information in order to help. Which version of Windows? is a big 'n/a' for a start & what made you think you had a virus, together with what 'malware' did you download to fix it?|
Sorry if I'm sounding unhelpful but in order to get help you need to provide a bit more specific information than you have done.
Just as a generic 'fix' and in case you are another one-off poster who will never reply again, try tapping F8 as the system boots, select 'repair my computer' (though this may not be there as we don't know which OS you have) and then try a System Restore when you get offered the option.
