A friend of mine is having problems when sending emails. When he forwards an email to someone it will send the email, put it in the out-box and doesn't delete from the out-box. So when he closes out outlook or sends another email it will send the first one again. Last night I ran Malwarebytes, removed 214 infected files, ran a boot scan with Avast antivirus, dug out 4 or 5 viruses and ran ComboFix and dug out a few more infections. This morning it is still doing the same thing. Are there some settings that I need to change to make it act right? Or what do I need to do to change this?
PS: after it sends the email it pops up an error box saying that an error had accured but doesn't give any error message. I am sending the capture of the error box for you to see
