run a virus scan. nothing from within limewire runs temporary internet files.

some great, free virus scanners:

AVG: free.grisoft.com
AVAST: www.avast.com

a great, free adware and spyware scanner:

Ad-Aware: www.lavasoft.com

i would also recommend clearing your temporary internet files cache. i don't use Internet Explorer, so i cant remember. and im not opening it up just to figure it out

a great, free browser all intelligent (atleast computer savvy) people recommend:

Firefox: www.getfirefox.com
