I am having problems with my Zonealarm Pro Firewall. I originally suspected it may be a virus or trojan, but I have been unable to find any malware on the computer.
The problem is the following:
Zonealarm does not start up with my computer anymore. (At least the gui does not - the truevector etc. is still running and protecting my computer). When I then try to launch Zonealarm, Windows reports that zlclient.exe is not allowed to run.
I did the following:
1) Scan with Antivir, Panda (online), Adaware, Trend Micro (online), BitDefender (online), Ewido, Trojan Hunter. They didn't find anything except tracing cookies.
2) I followed the description on http://nh2.nohold.net/noHoldCust25/P...tallNonNT.html
to uninstall Zonealarm.
3) I reinstalled Zonealarm.
4) It is still not allowed to run and I now have the added problem of not being able to access the internet or indeed use any programs with internet access, since Zonealarm is blocking them all, but is not giving me any opportunity to tell it to allow the programs access (this mail is being sent from my work).
My computer is an AMD XP 3200+ with 512 MB RAM.
I am running Windows 2000 (danish version, even though I am in US right now).
Do anyone of you have any previous experience with anything like this? Could it be a virus/trojan? Any help would be most appreciated.
