check the service's dependencies? run services.msc and find 'security center', click the dependencies tab.. make sure everything listed in there is started. it's possible the virus replaced one of the dependencies or added a new one that doesn't exist now.. if so, i believe you can clear that up with the registry check the screenshot for what i've got running.. hope that helps!
Yea do that and if all else fails try running system restore and restore to a time right before you opened that file dude. It may fail because of the virus but it is still worth a shot.
make sure the service's startup type is actually set to 'automatic' and if it's stopped to start it. if the dependency list is empty there shouldn't be anything in the registry u can do to my knowledge.. let us know if the service is set to automatic and is started when u get that error. if it was disabled try rebooting too.
Hate to say it, but your best bet is to probably wipe your drive and reinstall... And use a decent antivirus next time... like Avast or something.
all the AV programs in the world can't stop people from running retarded programs on their computer they download.
True, but it'll usually prevent them from running I got a bad app from somewhere recently, Avast gave me a warning mid download.
in my opinion symantec endpoint protection is good ive used avg before and that was too bloated. sep doesnt really bother the user too much it update when it needs to scans when it needs too all i did was install and restart and i havent had a problem with it since. small memory footprint 8 mb of ram used when idle(not updating or scanning just autoprotect) comes with firewall if you want it. anyways just my 2cents
Symantec uses WAY too many recources, not even mentionning the agony you will face if you want to uninstall ! That's not least to say, nearly impossible without the special tool from their site, and even then it is a royal pain in the butt. AVG's free AV is worth nothing, but their (new) commercial security suite is one of the best i've come accross, besides ESET (formerly NOD32). Now these two are my recommendations, as they give a warning at every threat, they even warn u when entering malicious reported sites, you can configure them all the way to the little details, AND they use very little recources. You won't even know it's there. They both have AV,Firewall,Malware agent,browser integration,heuristics,very quick scans,unnoticable daily updates,... Avast isn't bad either, but not the vest by a long shot. If you're gonna protect your system in the full, you should really give ESET security or AVG security a go, cause they're 100% complete and effective.
