Nasdaq referred me to this forum from my attempts to recover from a thumb drive infection. http://www.bleepingcomputer.com/forums/topic464272.html

First sign of infection: my netgear wireless modem and wireless network were renamed and all the passwords reset. Hard reset to recover. I am still getting browsers redirected daily. All three browsers each will give message that setting have been changed when opened. IE will say search setting have been corrupted and mandate Bing. Internet Options will be reset to custom levels without a reboot. I have installed AVG 2012 paid. No scan from various scanners will show an infected file except some cookies. AVG rescue disk scan found 13 password protected files that were renamed. Broke AVG and required a reinstall. Password protected files were back by the end of the day. AVG says there should be NO password protected files in their sub-directories during a rescue scan. Their solution is a wipe and reinstall.

What is the safest process of doing the HD wipe and reinstall? Just plugging the thumb drive in got me all this grief. Is reinstalling files from the DVD the same process? If i try to access my old files am i opening myself to reinfection?

Thanks for any wisdom you can impart...

<<What is the safest process of doing the HD wipe and reinstall?>>

As suggested by Nasdaq...format/reinstall Windows will do the job.

<<If i try to access my old files am i opening myself to reinfection?>>

What old files are you referring to? If the system is infected and you intend to do a wipe/reinstall...what files would be available for "access"?
