Everytime I click on something in Firefox I get system23/yehmyv.dll not valid windows image. What do I do?

Question

I tried updating Firefox but still get the same message. When I used Explorer (YUCK) I did not get the message even though I went to some of the same sites. The entire message reads: DLL C:/WINDOWS/system32/yehmyv.dll (should be back slashes) If I click ok it goes away but comes back almost everytime I click on a link. I can work with it but it is annoying and I'm worried about potential problems cropping up. I ran spyware and checked my firewall. Don't know what to do next

Answer 1

Also do a malware check with some malware scan programs.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of the database before doing a scan.<br />
