Hi everyone, I'm glad to be part of this forum.

I right now have a problem that I can't find the solution to. My Norton Antivirus told me that I had a backdoor.trojan but it was unable to move it. Later on, my PC suddenly went off by itself and all subsequent attempts to put it back on led to it shutting itself down. I looked up how to remove backdoor.trojan at the Symantec website, and followed its instructions. First I disabled System Restore, then I went into safe mode and ran a full system scan. However, the scan this time showed no viruses on my PC, so I reset my PC and went back into normal mode. The PC worked relatively OK and was no longer shutting itself down, however, all the games I have on my PC are now much slower. Also, if I try to run winamp together with another game or programme, things still move slower. I'd like to know what I can do to fix this.

I have a:
Dell Dimension 2300
Intel Pentium 4 processor
CPU 1.79 GHZ
128 MB ram

Any help will be greatly appreciated.

Have a look at what processes are running ctrl alt delete to bring up the task manager or right click the taskbar and click task manager .

I did as you suggested and ran the scans. There was another virus that Norton Antivirus didn't see (bck/agent.ef) and I was able to remove it, but the slowdown problem still occurs. I ran a game whilst leaving the task manager on and saw that CPU Usage jumped to 100% whenever a game was on. What I'd like to know is how do I stop this from happening.

128mb isnt exactly a lot of ram.

Are you using Windows ME or XP??

If XP, then you definitely need more ram. Lack of ram, will make your system go slow.
