Obviously, Malware has become a serious issue over the last few years, infecting more computer systems on multiple platforms (Microsoft and Apple). As of yet there is no 100 percent effective way to stop all of these programs.
The most common means of a malware program is no longer to steal information in the traditional virus sense (via keyloggers, monitoring web access, etc.) but is now primarily focused on voluntary submission of personal banking information for monetary gains.
How do you know whether you are infected or not? The most common is an unfamiliar program will suddenly appear claiming there is an issue with your computer system. Commonly malware disguised as a fake program utilizes several means of appearing legitimate, such as using logos or names of software or hardware components.
Successful ways to prevent infection of this software is to become familiar with your protection software so that you know when it is updated and should a malware program trigger you can recognize it as such. You may use the hotkey Alt+F4 to shut the malware program down should it bypass your virus protection, hopefully preventing infection. There are also companies that sell Malware Protection and do a better job at stopping these programs than an anti-virus provider.
The most notable effect of malware is lost time and productivity, since they will attempt to halt all work being performed on the system, some even prevent their removal. If the program is successful at obtaining your bank information there could be monetary effects to the infection as well.
