hi, i always get this error at the time of window starup and sometimes even after that again:

autolt v3: rvhost.exe-application error
the memory "0xx...."referenced the memory "0xx....".the memory couldnot be read.
click ok to terminate.

is that a virus or something or is that due to some corrupted file. i tried to sort it out using my antivirus and anti spyware but it didn't work.
please tell me, if anyone have any idea, how to sort it out.
