Hello.
Thank you for the file. It is indeed malware, but guess what? It's a new version of something, not exactly sure what right yet, only 3 scanners find something.
Microsoft 1.4803 2009.06.23 PWS:Win32/Pemsepos.A
NOD32 4181 2009.06.23 a variant of Win32/Kryptik.SR
Sunbelt 3.2.1858.2 2009.06.23 Trojan.Crypt.Krap (v)
Please download the LSPfix from here: LSPFix
Unzip it to the Desktop (Important!!) and run it. Check the box that says "I know what I'm doing", and then select each instance of "lspcfm.dll" in the left-hand panel and click >> button to move it to the right-hand panel. Then click Finish to allow LSPfix to rebuild the LSP chain.
Reboot normally and your net connection should be back.
