For a couple days now, I've been having issues with my computer. Everything is slow & will freeze randomly. Sometimes the freeze is short, about half a second to a second when listening to music (very reminiscent of CD skips) to over 5 min when opening new pages in Firefox. I did a whole computer scan with my AVG & it tells me 8 threats found. All of them are Sysenter Hook. I've done scans on all the other computers in the house & none of them have the same thing. I did a Yahoo search for 'sysenter hook infection' and this page - http://www.bleepingcomputer.com/forums/t/511472/sysenter-hook/ - came up.

 

I have done the scan with DDS & have attached the resulting files to this post. I'm hoping a moderator or someone with more malware know-how can tell me what it all means & if I should go ahead with the next step.

 

Thanks in advance for any help, this is my work computer so I really have to make sure its in good condition or I can't do my job.
