Scam artist trying to get my computer infected to steal my info

Called 3 times in the past week.  Sometimes the name appears as "Charles Balina", sometimes as a jumble of letters and numbers.

Called, I wasn't home - they left no message.

Listed as from Twin Cities, MN. Heavy accent. Could hardly talk English correctly. From what I could understand, the lady tried to tell me my computer has some malicious code running on it. But she didn't use those terms. I asked her what company she represents. She said 34y7PChelp, if I understood her correctly. She didn't seem to want to divulge that info. Doesn't seem to be legit to me!

got a call, someone saying my computer had "alerts" on it and needed repair. I ended up hanging up on them
