hi folks! i have a disturbing problem with my machine. once in a while, while working with my lap top it suddenly starts to beep and 3 of its lights are blinking. after one minute or so it shuts down. i didn't manage to do anything against it. i have two other problems which might be related. a while ago, i was surfing the net unprotected and got infected with all kinds of #%@#. i managed to remove most of these pests, but my AntiVir now displays the message "can't create a report file" before preforming a scan. then, the scan detects an IstBar trojian (ysb_regular[1].cab) which it can't fix since "infected files in archives will not be deleted or repaired".. i downloaded and ran the Symantec Cooperation fix tool but it didn't find IstBar on my computer.. i use winxp and still did not update it with the 2p2 service pack .. i would be gartefull for any kind of help. cheers, yoyo
