I'm Working as an IT in a school and you would imagine the sum of the viruses we get everyday from students teachers and stuff. we are facing 2 different kind of viruses.
1- scan for virus,s ( right clicking an application and it will display scan for virus,s among the list such as open, Run as and etc. )
2- Open application as well a virus ( right clicking any folder or app. brings it in the list of choices)
1- Most antivrus is effective for this kind of virus was Escan. Tried Norton Mcafee Eset Trendmicro non were effective.
2- Downloaded and Installed ComboFix.
3- Deleting it manually from Shell folder in the regedit.exe
4- W32 removal that i found on one of the websites but it wasnt helpful.
can i resolve this in a less / easier way?
Another virus we are facing is shortcuts anytime some1 use his usb in an affected PC his folders disappear and everything turn to shortcut.
(As you know in schools if the teacher have saved his quizes sheets Tests and exams in his usb then it got damaged he will be in big trouble. since his computer is affected and there is no way to save his documents anywhere else).
1- Unhide the folders by chosing unhide protected files so we can remove the viruses.exe manually. antiviruses cannot detect all the viruses.
2- deleting the shorcuts. (got sample though)
3- using the command line to fully unhide the folders. attrib -r -a -s -h /s /d X:*.*
the problem is even after cleaning the computer and usb still they are getting the shorcuts and its really killing us in the IT department going and cleaning the 100s of PC and USBs over and over and over again.
is there a better way , am i missing something ?
( we do use the app. freeze in our labs so it will automatically delete any file that enter the pc.after restart)
