Norton Power Eraser failed to remove every threat found
Plugged in a old external hard drive my friend gave me. Thought I should scan it since he's computer illiterate.
First I scanned it with Norton Internet Security 2011. Scanned it and it found quite a bit of viruses. NIS2011 removed them just fine. Then I went to use Norton Power Eraser to ensure this hard drive is clean. It found many threats. Checked to remove them. NPE told me to restart. I restarted. When It boots up, I logged in. NPE pops up ant tells me the removal results. Failed to remove every single threats. Does not give me an explanation or more information. Now I feel unsafe. Here is a link to a screen shot I took so hopefully someone can help me fix my problem.
By the way the computer I tried this on is a Dell 4600 running Windows XP Home edition 32 bit. It has a 3.06GHz Pentium 4 HT CPU and 2.5 GB of RAM. It is up-to-date in both Microsoft products and Symantec products(NIS2011 and NPE)
Please improve Norton Power Eraser.
Thanks in advance.
