It worked very well for me. I had a bit of a hard time to get it started, but after properly reading the instructions it did the job. Fixed my new PC as well and my old computer that is still using Windows XP. In total it cleaned up 10 threats. Having this USB stick to continue checking up on my computers will be an asset. The Norton Antivirus software does not allow it at first, but it works at startup before Windows loads up. No problems occurred after its use and both computers worked better without any sluggish delays.
Bottom Line: Yes, I would recommend this to a friend
