Drive Shortcut Virus As the name suggests, Drive Shortcut virus creates a shortcut of the whole removable drive. This not only limits to Flash Drives or USB Drives but can also affect External as well as Internal Hard Disks also. This type of virus is purely trojan where after entering into your Removable Drive, starts overtaking your files, grouping them and finally making shortcut of your flash drive. After the virus does it’s work, the only option you’re left with is, double click over through that shortcut to open the contents inside that drive, and at that time, the malware executes, which can do anything (according to the way the malware is coded) like spying on your PC and browsers, steal passwords or just about anything. Folder Shortcut Virus Self-explanatory, folder shortcut virus creates shortcuts of folders and wraps it’s contents (files) altogether. Less effective, but steal can spread itself after executing to number of other folders from where it can spy over on activities, upload data from that specific folder or do anything within the folder. File Shortcut Virus A virus that makes shortcuts of program files. While this type of virus is the least effective, it can do more of damage when it attacks an important software’s execution file (.exe). On getting executed, this virus can also do just about anything inside the scope of that software. It also rapidly multiplies itself once it’s executed. The way all these viruses work and affect is different.
