Yes it can but you have to know which files are virus files and which files are not. Since this is practically impossible to know each and every file, it is best to use an antivirus because it's been programmed with all the virus files already so you don't have to guess. That being said, look for files with seemingly random names and recent dates. When in doubt, you can google search a filename to determine if anyone has flagged it as a potentially unwanted program. This method is not 100% nor is it recommended; deleting the wrong file can cause your computer not to boot up.
