To be fair Jhensen is quite right you should always go to your Admin, but as a side note you dont really want to be circumventing the Network security it is there for a reason regardless of how much of a pain in the ass it is.
That also means trying to remove DLP is really not wise for you, most companies these day's get you to agree to a computer usage policy and by you removing or disabling elements of the program that is desinged primarily to protect you will land you with a possible meeting with your manager for breach of this policy, every company's diff but it really is not worth your job.....period!
Autorun Virus and Trojans have made a huge comback as a result of an increase in removable devices and sloppy Admins not removing the Autorun facility within the Registry on Corp Builds, this one little change will scuppure most Viruses and any decent AV program will clean the little blighter as soon as you access the device hence the term "On-Access Scan" sometimes only a Format will surfice as some more stubbon Viruses will cause a stack overflow within the Explorer Shell so will cause your desktop to essentially reboot (Simple way of looking at it is that it looks a bit like your loggin off but withouht the message boxes e.t.c) preventing you from even access the device, you may even have to Format it through Safe Mode but this is not recomended as your AV will likely not be running in Safe Mode so will not protect you, YOU HAVE BEEN WARNED.
if you modify the reg keys e.t.c dependent on the Log settings set via the EPO admin it can easily be flagged back to the Server and will often invoke a Policy enforcement which will remove any changes you have made and this will happen every time you log onto the company network unless they have it set at certain intervals of course, (Reduces network loading at certain times E.t.c)
Again to to assist with the question raised by Teojosh, there is a little hack you can try mate I dont recomend it for anything else but have used this little method for several shall we say "stubbon" programs Encountered in the past, you should providing you have taken control of the McAfee folder within Program files be able to simply right click on the folder and delete but let it sit in the recyle bin never delete it untill you have perfromed serveral reboots to ensure everything still works,
now when you go back to Add/Remove programes when you hit the remove button it should give you a small error to advise it could'nt find the program and do you want it to be removed form the Add/Remove list just hit yes, do a reboot and check to see if any McAfee services are running withing Proceses withing Task Manager.
It may be prudent at this stage to run the MCafee Software removal program just to clean the system up a bit!
Any Probs post back and I will assist now I'm back on the Scene........
