While watching a online video episode, the graphic (picture frames) started to ''skipping'', and (slowing down) during playback. Whould a (system restore) resolve the stuttering safely ? I immediately took the disturbance as a act of incoming (malware, spyware & virus) attack. I did a (emergency-shutdown) of the PC and started using my installed maintenance software, such as my PC Cleaner. Is there any suggestions about (online attacks) to resolve ? In this case I had to re-install (Google Chrome).Lee Payne
