I believe I may have a trojan lingering in my system. NAV 2005 told me I had a Downloader.Trojan virus (filename 0g1sa.dll). So I used the trojan removal instructions I found on another forum and the anti trojan program Trojan Hunter found the virus (0g1sa) and deleted it. Then I ran TDS-3 and it found a bunch of Hidden ADS streams, so I deleted those and some of the host files. So after everything was done, I restarted my computer in normal mode and everything seemed to run a little better (the HDD light wasn't on all the time). Then after a short time, it started again, so I tried to find the program in Task manager and came up with two processes I hadn't heard of before, crtv32.exe and msjz.exe. I was able to stop the process crtv32 process, but the msjz process kept reappearing as soon as I stopped it. Eventually so did the crtv32 process. I then happened to come across this log called f2install.log in my root directory: >>Install Start...

And does anybody have suggestions on how I get rid of this thing?
