Sir, I need ur help..... i use my Flash drv in another computer of my friend. This computer was infected by viruses. Now when i attach it to my computer again..... the message i rcv is of internet explorer, as u know it has two button on dialog box: Connect Now----&---Cancel. This message is repeat again and again after a duration of 2-3min or whenever i clicked any activity....e.g. when a process is going to be execute. I hv XP installed on that machine. Now i cm to my office...and attach this flash to Windows Server 03.....machine...it give me the message again and again...on dialog box.... You explorer is stopped to execute for security reason.....to avoid third person to view ur system. ........As far as i know the infected machine of my friend has an error message: SSvchost.exe (like that i think) when he log on to windows.....and machine was to slow at that time to log on...... Kindly tell me that is these two are different problems or are same in any way........ and guide me plz that how can i troubleshoot both of these problem. Sir i will really appreciate ur this kind response..... bcoz all of my office work is stopped due to security reason. Thanks alot!! Syed Fahad Hussain
