Hey ranamalik. If you've already tried to access your card on your computer I'd recommend that you install an antivirus program (if you don't have such) and update its database. Then run a full scan on your HDD. After it is completed, plug in your memory card and scan it with the antivirus program you've installed. If it detects any infected files or threats it will prompt you to take action (usually delete the file or quarantine it.)
Hope that helps.
