Hi, I am a new user of Parallels, so I am not sure if I am in the right place. I installed Parallels 4.0 and Windows XP Pro on a new MacBook Pro. Everything seemed to be working fine initially (including Windows Explorer). However, yesterday I tried to launch Explorer and got the "Explorer has encountered an error and needs to quit" message. Does anybody have any suggestions? Since it is the only web browser installed on Windows, I cannot access the internet from Windows right now (or I don't know how to do so). Thanks!
Frank, Looks like viruses. Please scan and clean the VM with free CureIt utility: http://www.freedrweb.com/cureit/ Then, install Parallels Internet Security or any other antivirus software, to avoid this in the future.
