I have an old laptop which I brought home from work and which I let my daughter use. The problem is that it has an old version of Symantec AV which interferes with Avast's Resident scanner, ie with Symantec's on demand scanner running, Avast disables some of its services including its resident scanner. I can't remove Symantec because its protected by my employer's old administrator's password so I can't delete it from the system. The administrator left the company a long time ago and nobody knows what his password was. I've renamed all of Symantec's .exes but the on demand scanner is still running. By renaming the Symantec directory, it crashed the PC so that's not the solution. Does anybody know what Symantec's on demand scanner is called so I can disable it, ie reneame it ? Any other suggestions ? Thanks
