Anti-Virus program won't open

[Randymarsh9]

I am using Symantec Anti-Virus as well as Malwarebytes. Somehow my computer got a lot of malware even though I haven't even gotten on it in 3 days. I am using symantec to try to clear them up, but it doesn't really do anything. Malwarebytes won't open no matter what I do though. I'll click the shortcut and nothing will happen. I even went into the program file and clicked on the .exe and it still didn't open it. Does anyone know how I can fix that? If I could just open malwarebytes I know I could get rid of all the stuff.
