When done, delete this file:
C:\WINDOWS\SYSTEM\
boln.dll
and see if you have anything like
d: oo.mht. If so delete as well.
Now surf to
www.grisoft.com and get the free AVG antivirus. Or buy a commercial package (NOT Norton). Install it, update faithfully and run regularly.
Oh, and stop using Internet Explorer, except for Windows-updates.
Install Firefox from
www.getfirefox.com and use that from now on!
