Virus attacks are often responsible for unpredictable security issues in a computer system. One such manifestation of virus attacks can change files on an external drive to shortcuts. It is possible to solve this issue and retrieve the changed files by using software such as Autorun-Exterminator. The Autorun-Exterminator removes the autorun.inf files from the external hard drive. Once the autorun.inf has been removed, the attributes of the files can be changed by using the attrib command so that files that were changed to shortcuts can be restored. Anti-virus and Anti-malware software must be installed to prevent attacks in the future.
