Hi guys, The most common virus that I see nowadays, which has infected almost all systems, is the (Virus Name Here) which commonly propagates through user's USB flash drives (commonly referred to as Pen Drives). Though it causes little direct harm, like other viruses, it keeps running itself on startup, and wastes CPU time. So, here are some steps to follow to prevent it, because Prevention is always better than Cure.
NOTE:Linux Users don't need to read it, because statistics report that almost none of the linux systems are infected by viruses.
