Hello, My avast virus software detected a trojan virus - it didn't specify which one. Symptoms include many ad pop-ups. I also am getting a dos window with the header c:\windows\temp\h91746.exe and a window with the title - '16 bit MS-DOS Subsystem' and text that reads: c:\windows\temp\h91746.exe The NTVDM CPU has encountered an illegal instruction. CS:0575 IP:01d4 OP:63 68 65 2f 31 Choose 'Close' to terminate the application. My problem is similar to someone else that posted, but our HT logs are different. Thank you very much for any help!

reboot in safe mode,(may need to turn off system retore) rescan for viruses and scan for spyware, delete any found files,if undeleteable, put in trash, empty temp folder, empty temporary internet files, empty trash, ... post hijack this log if necessary,

Okay, I booted in safe mode. Scanned and deleted virus files. Deleted everything in Temp and Temporary Internet Files. Emptied Trash. Rebooted and... ...Avast is still detecting a virus. So here is my Hijack This log. BTW, thank you very much for attending to my problems!
