I went through an online microsoft site to have a so called expert go through and fix all the registry errors on my computer and eliminate viruses…. I did the security tool removal myself last week and now I have the siszyd32 virus and maybe either it or something else is hijacking my computer to send out spam or something, probably trying to send itself to other people. I’ve deleted all of my contacts and everything so it can’t spread itself anymore and I’ve installed hijack this, but I can’t find the siszyd virus anywhere in the log it gave me. Any help would be appreciated. Here’s the logfile I saved:

Hallo, hier mal eine Anleitung: Ihr ladet auch “FreeFixer” herunter das Programm kostet nichts. Dann startet ihr Windows im Abgesicherten Modus. Danach müsst ihr FreeFixer durchlaufen lassen. Nach dem Scan steht dort dann ein Scan der auf siszyd32 verweist. Dort auf “Delete”. Dann nach unten Scrollen und “Fix” klicken.

Danach im /dokumente und einstellungen//programme/autorun (oder so ähnlich, den richtigen Pfad findet ihr bei Freefixer) die Datri siszyd32 löschen und entfernen aus dem Papierkorb.

Dann läuft das System einwandfrei.

Eventuell noch mit AVG durchchecken lassen.

Fertig :D

You won’t find “siszyd.exe” on your computer… there is a second Startup item that loads a DLL… and that DLL dynamically write the file in you STARTUP folder, loads it as a service show it shows up as a SRVCHOST (DCOM) using 99% of the CPU.

OK, I have no idea what the thing does but it does seem to commandeer processor time and bizarrely enough asked for permission to connect to the internet via zonealarm. I was alerted to this bizarre behaviour because it was a ~tm169.tmp that seemed to want to execute as an exe.

I said no – but stupid me ignored that even though it didn’t connect to the internet it did however drop a file siszyd32.exe into the start up folder – but you take a look there and no it is not there! I noticed that Skype literally crawled across the internet every website was slooooooowwwwww and that using Task Manager revealed that this little svchost file (why don’t they identify “this svchost instance is xyz” etc in Task Manager – surely that little programming gem didn’t require rocket science) that was helping itself to 99% processor 1. Don’t know if it can spawn off other processes that will then take over processor 2.

So, I did my usual antivirus using AVG (free – I was happy so far) and that revealed nothing. Googled the mysterious siszyd32 and bingo, and it is someone’s little New Year’s goodie to us.

Right – you want to know how I got rid of it?

1. Choose the simplest route – not like me creative brain surgery on the registry coupled with msconfig – too slow and it doesn’t kick the process out of memory although the fun of removing the registry entry for Poker themes (well that is apparently what it described siszyd on my machine) was quite rewarding. And if does make you feel better then go to your Windows temp folder and delete any files such as ~TM167.tmp (I had three files all created at the same time and noted the time which is immensely useful if you want to extrapolate when and how you got this gift that keeps on giving – if you have firefox look at your history for that time).

2. Having concluded that you now want to use the simplest route – download Malwarebytes Anti-Malware (google it) – install, update, and run it on a simple scan.

More than likely once it has finished it will either give an all clear or you will be advised of what problems are on your machine – you then choose what you want to remove (basically just follow instructions) and then reboot at which point it will kick the process out and restart clean.

3. Rerun the anti-malware and check it has gone.

4. For a final flourish you might want to create a restore point and call it CLEAN after VIRUS or something like that.

Hope this helps :)

yesterday, my PC was also slow because of this SRVCHOST (DCOM) using 99% of the CPU.You will get siszyd.exe in startup.
Download HiJackThis and MBAM from
HiJackThis log will show siszyd.exe in startup.
Use can use MBAM to remove siszyd.exe.

Hittar ingen syszyd.exe som sparks sa. har kört freefix utan resultat. i msconfig kommer syszyd alltid tillbaka och lägger sig som autostart. hur många gånger jag än bockar ur rutan.
hittar inte heller någon srvchost varken i aktivitetshanteraren eller i systemfoldern.
så störande! har aldrig misslyckats med att fixa ett virus förr. men svårt att fixa när jag inte får tag i en enda fil av viruset.
formatering som gäller eller?

K, well I tried everything I’ve seen so far. MalwareBytes doesn’t even recognize the siszyd32.exe file as a virus and picks up no threats from it, I located the file, scanned directly and nothing. The only files on malware that conclude as a virus is a rootkit.agent file called furumcnp.sys which is in my drivers file.

Found something called ‘freefix’ and tried it. Same as malwarebytes, nothing poped up. Then came across hijackthis, and -still- got nothing at all. Yet, when I restart my computer it still says the siszyd32.exe file is there. Both me and my gf got it in the same day on our computers, and haven’t been able to get rid of it. As for the hijackthis log file, it goes as followed.

Any help at all would be useful, because as of now I’m not sure what to do.

Also, my girlfriend scanned with AVG which also did not pick it up.
