(I've just posted this on the internet security forums and thought I might get a response if I post it here to) Hi everyone, It seem that my computer has a virus which is screwing my computer up in very random ways. I believe I caught this virus when I was on MSN Messenger. I was in a conversation with a friend. What I thought was my friend sending me a message was actually not him. I recieved a message saying: "Is this you?" and then a link next to the text. I clicked the click which seemed to be an openable file but nothing happened when I opened it. I became suspicious and talked in person to my friend who I was in the MSN conversation with and he said he hadn't sent me such a link and he had a virus on his computer which he had caught the same way. So, at first nothing seemed to be effected but now many programs won't open or work properly. For example, Microsoft Word will not open, MSN messenger won't sign in, I can't sign into to my university email, my Norton Security software will notopen on start-up. However, I can still surf the internet and my computer fires up as normal. Before I ask for a diagnosis and possible soultion first of all I must warn you that HiJackthis will not open when download the .rar file. As soon as I open the file, it closes. asqaured and sybot search&destroy will not work either. What is going on and is there way to fix it? Thanks alot.
