I installed Vipre Internet Security 2014 two days ago and removed Norton AV. Vipre is currently running. I just completed about four days of "fixes" with RPMurphy (BC) which was followed by the Vipre install/Norton removal. The thread for that problem is at: http://www.bleepingcomputer.com/forums/t/518865/infected-trojanagentgen-symmi-gen-zbot-unable-to-remove-with-sas-or-mbam. RPMurphy did a great job ! Everything was fine - for a little while. Slowly, the computer started acting a little weird, mouse is a little jumpy, sounds crackle a little bit and at times, stick (but not during a test), programs would take forever to open, processing became slower, and slower, and slower, etc. All the time, Vipre was running and no threats were detected. I actually haven't had much of a chance to even use the PC to allow another virus in the door! I have since verified the drivers for the mouse and sound card, ran chkdsk /f no problems were found. I also ran Ccleaner and cleaned up all the garbage that was still hiding out on the PC. Just now, I ran, Speccy (very latest version) and it indicates (under Operating System) that Norton AV is enabled and that ThreatSecurity (Vipre) is disabled! Is it possible that there is some sort of conflict occurring in these programs due to some portion of Norton that was not uninstalled? Could this be causing the fluctuating mouse, crackly speaker noises, etc? Since I just finished up virus removal with RPMurphy, I don't believe that this is a virus problem and I am thinking there is something in the software side that is causing these problems. Maybe it's just me? Any help will be greatly appreciated.
