Let me tell the prob. From starting I just plugged a Mob. MMC to my pc and scan using AVG 7.1 Antivirus its result is no virus but rit after the scan pc hung by showing card reader error then I press restart btn after booting I can do all normal operations but I cant access the MMC I tried another MMC also but the result is same but without MMC the card reader is not showing any prob. Then I notice that my AVG auto protection is not loaded I tried manually but the loading sequence terminates before completing the loading sequence I tried to reinstall the antivirus but its also showing the same problem sometimes the explorer terminates itself and reload wile accessing the CD drive then I tried to terminate some programs by using task manager but the task manager don?t stick much time, so I cant select the task and press end task. Then I tried msconfig it is also showing the same response. But I am able to install pctools spyware doctor it detects 47 spy ware I removed it and scan again but the result is the same scan you please give me a solution for this problem to run my pc normally.
