I recently let somebody use my computer and they really screwed it up...they somehow managed to download "malware" on my computer which came along with a couple "behaviorals" and a couple trojens...One of which somehow destoyed my mcafee. So I bought spy sweeper antivirus and i think i got all the bad stuff off. But now when I am online, I can't hear any audio. I can hear audio on my windows media player and any offline games i play. I tried going into control panel and adjust the volume, but it is saying that I don't have any audio devises hooked up. Also, my volume button on my keyboard no longer works. The volume on my moniter works and the volume on my 2.1 speakers works. I also can no longer get into my mcafee, i can't even uninstall it...everytime i try to do anything with it, mcafee screen appears and disappears within a couple seconds. Please Help!!!
