Don't know if anyone has come across this on their computer. Somehow something has got onto my computer that generates a laugh sound and a slamming door sound. This happens at random times. I have up to date anti-virus and have swept for adware and spyware, I am at a loss to know where it came from, or what it is. It doesn't appear to do any harm. For info my anti-virus is Trend Internet Security and is upto date, and sweeps regularly
Yes I am on AOL (I wish I wasn't) Don't use MS Messenger As far as Apps running there doesn't have to be any running. It only happens maybe 3-4 times in an evening between for example 6-11. It might happen within a couple of minutes and then not for an hour or so.
Get hold of a system cleaning app like Evidence Eliminator (EE) or Windows Clean (don't know whether that is right title or not), there are a number of them out there. I use EE and it gets rid of everything temporary, designated files and folders and all IE histories and so on. I believe it's a free download from EE's site, I got it from a cover disc. I don't know whether it's my imagination or what, but since I have been using it over a year or so the machine seems to defrag quicker and I don't get much unwanted interference from Spam and suchlike, perhaps because there is no history on my machine whenever I access the net. Anyway, if your noise is a temporary file or cookie, EE will get rid of it, it's worth a try, and it's free.
It's also worth looking at what apps start with the machine. Quite a while back I couldn't get rid of a couple of naughty icons, until I found that they were in the start-up list of msconfig in 98SE. I used EE to get rid of them and my desktop became maiden aunt viewable again. Good luck.
