Dear Mr. /Miss.
I did deleted the RVHOST.EXE file from my system but still whenever I logon on my windows I get a message says (Windows cannot find the RVHOST.EXE) this message mean that there is a service or a command trying to executed but it could not find the file specified because I did remove it.
Please advise me to find where is that place to stop getting this message whenever I tried to login.
So, give me reply as soon as possible

You could run your Main Operating System disk and recover the file. The question is to vague. Need to know which version of operating system you are using.

I keep getting an invalid backweb application-8876480, my sysem isn't starting properly and I only have one system restore point. How can these issues be resloved short of restoring because I'd lose everything?

Please \reply ASAP.
Thank you
Mary Britton

Just a work of caution, if you install prevx, you will never get rid of it no matter what you do
