With F-Secure I can block malware and threats from devices like pendrive

I am not sure about the virus or malware called pendrive but I've been using F-Prot since 1998 and fortunately have not had a virus infect my computer since then. The only issues I've encountered have had to do with Autodesk updates and installs not playing well wit F-Prot's hidden programs such as F-Secure. If the process of F-Prot are not all shut down before trying to install an AutoDesk update or program my computers will BlueScreen! I've worked with the developers of F-Prot and Autodesk trying to solve this one but to no avail. So the work around is stopping all Cyren products then install. Love that it works seamlessly in the background keeping things safe
