I just installed CCleaner. When I clicked the download, Google Chrome gave me a warning that "This type of software can harm your computer." I'm new to Chrome so maybe it says that about all .exe files. My wife had CCleaner installed by Best Buy, so I continued.
During installation, my Symantec system protector gave me the following notice:
Scan type: Auto-Protect Scan
Event: Risk Found!
Risk: Adware.CWSIEFeats
File: C:\Users\Mitch\AppData\Local\Temp\xtcG0kIq.exe.part
Location: C:\Users\Mitch\AppData\Local\Temp
Computer: PORTABLE-OFFICE
User: Mitch
Action taken: Pending Side Effects Analysis : Access denied
Date found: April-11-10 9:12:36 PM
Apparently, this file piggybacked on the download. Good going, Chrome. Good going Symantec. I'm going to reboot now to see if it was worth it!
