It says:
WINSERVS / PurityScan / sear1.exe (winservs.exe, winservn.exe, etc.) - On first running, scans your IE cache/history/cookies for files with porn-words in them and displays a list of any found. Also drops in a background program (winservs.exe) that constantly loads popup ads when the computer is running.
