5. Scan PC for Virus or Malware

If you make downloads more often then, there is likely to have a Virus or Malware on your PC. It not only corrupt or compromise your documents or media file, but also lowers down system performance, and as I stated above unknowingly. Thus to resolve this issue download and install a verified & reliable antivirus and perform a complete scan of your PC.
