How can I stop my pen drive from getting effected? My pen drive gets infected every time. Even in the computers containing anti-virus. I have a 4GB Sandisk pen drive. Most of the times if I create folder or access something contained then few files naming "ΩäCÄφyu.┼" or "√¬O+úφ.$⌡"" and so on. I try to delete them but a message "Access denied" is shown. Even if I scan the files are not removed. i even can't format. Sometimes few inaccessible folders are automatically created. It is displayed as <Ï> file or 'UQ" file and many more.How can I remove virus in my pen drive permanently? Whenever I use my pen drive at least one folder will catch virus. Even if I scan it and remove it. This especially happen to video clips, and Ms-word documents. Now it has even spread to photos also. I don't know what to do. How can I remove it? Please help me.
