Windows Explorer is a service that needs to be running with Windows..
It should not end..
I'd do a virus scan as well as adware and spyware to be safe.
For a free online scan, I reccomend:
(It runs right through your browser).
For an adware scanner, I reccomend:
Ad-Aware Personal from http://www.lavasoftusa.com/software/adaware/
For a spyware scanner, I reccomend:
Windows Defender (Beta 2) from http://www.microsoft.com/downloads/d...DisplayLang=en
After you clean your computer, I'd reccomend buying an antivirus..
NOD32 is an exellent scanner and can be found at http://www.nod32.com/home/home.htm
If you can't afford to pay for an antivirus, get AVG Free at http://free.grisoft.com
