Dear sir, I Am recommending You to download Clamwin portable. You can get it from The following link. http://freefr.dl.sourceforge.net/project/portableapps/ClamWin%20Portable/Add... Run The download .exe installer and install The product to The empty folder. Run The clamwinportable.exe and confirm, that You want to download The virus definition database. After virus definition database will be downloaded, exit Clamvin portable. Burn The whole folder structure including The sub folders to The CD-R media and take this media with You. varning. Clamwin portable is not so good like Microsoft security essentials. You can only scan or remove The files when virus will be found. Clamwin will clean and analyse The computers memory for malvare processes. The best solution for You and others administrators, who are visually impaired will be Windows8, when Windows to Go will be released, You will be able to take Windows8 installation with You on USB flash disk and You will be able to use Microsoft security essentials to clean viruses from The host computer. Triing to use antivirus from infected system can have The potential in various system instability issues. The realistic solution for You is to use some Windows PE live project to create The live USB or live CD. I have tried to install WIndows8 to USB external harddrive to make my virus cleaner tool on external USB harddisk, unfortunately, installer stopped to work after booting. Take in mind, that when You will use some live project, The virtual memory will not be available and that virus cleaning will take longer time than running it from normal Windows operating system. It is sad, but i do not know about Clamwin portable variant for Linux. So try to run Clamwin portable from The infected system and try to test this tool, what it will do with The system. Please let us know about The results of using clamwin portable with applied virus database update. When Clamwin will find The virus, it will let You know. If You will want to remove it, You will have to use options menu to specifi, that You want to remove The viruses.
