I downloaded a file from an archive which had the zeroaccess virus which I did not knew. I ran the file and it disappeared and blinked my screen once. Next thing I know is my antivirus protection software which is Mcafee Antivirus Plus keep telling me that it found a potential threat virus and needs to restart the PC in order to delete it. I rebooted the PC but the same message again. I rebooted couple of times but nothing happened. Then I went online to look for the problem and ended up on this forum posts from previous users. I tried to follow some of the instructions of running different softwares as mentioned in the post in that order.
I think I have removed the virus(not sure) but I still think my services.exe file is infected. This is because I do not see th svchost.exe file running anymore in the taskmanager. Previously I used to see a couple of instances of the same file. Also I am not able to manually turn on the firewall service. Even the firewall in my mcafee antivirus plus keeps turning off once repeatedly. Everytime it turns off I turn it on manually and after some time it turns off again automatically.
I have used TDSSkiller, rkill,Roguekiller, adwcleaner and all other instances of software mentioned on this forum but to no success. Also for whatever reason I am not able to completely run the Combofix software. It gives errors out something like wrong syntax of command or something like that.
Currently if I run any of this software, I cannot find any trojan or threats any more but I I donot know why my firewall keeps turning off.
Looks like I have to replace services.exe file from my installation DVD or something else?
I read on one of the forums that my computer may have been compromised and my personal information may get leaked. Is this possible? I can see this happening with firewall off. I would like to refrain from formatting my hard drive and reinstalling everything but worst case if no option am willing to do it but I just want to make sure I do whatever is possible first before taking the last and the ultimate option.
Can somebody help me with my problem?
