Need Help With Virus That Slows Down Computer Significantly


Recommended Posts

I'm not completely sure if it's' a virus, but this has never happened until now. After about using my computer for about 20 - 40 minutes, the performance of my computer becomes extremely slow, and frames freeze for minutes. When this happens, the performance never goes back to normal -- I'm forced to shut down my computer by using the power button. I'm sure that this is a virus, because my computer is a very good one, and I don't leave it on over night or anything of the sort.

Please help me, this is getting extremely frustrating to deal with, especially when I'm playing a public match on video games and I have to shut down my computer and waste 5 - 7 minutes rebooting and opening up the game again.

I have run the disk check and the system file checker. I have also run Microsoft Security Essentials and it tracked 4 Trojan viruses.

As I said, I'm unable to run the Event Log service due to the error I mentioned earlier, so I'm not able to run the Event Viewer.

Also, my access to the CBS.log is denied.

However, after doing all of this, the problem has not been happening anymore. I believe it has been fixed, but I will wait 24 hours to be completely sure. Thank you for your assistance!

icon_exclaim.gif Running it on another one may cause damage and render the system unstable. icon_exclaim.gif
