Question

Windows XP problem

Dec 26, 2013 6:58AM PST

I had win XP service pack 2 till few hours ago.
It worked fine (awesome), no problems at all.
But when my friend tried to install avira antivirus it required service pack 3. So he installed it.

Now when I turn my computer on, it is much slower than before. When I launch any program it is slow as a snail. Also when I play any video (for example in youtube)
I can't watch it, sound goes fine, but image is frozen or vey slow moving...

Is there any way to speed it up?
or
If I uninstall service pack 3 from:
control panel/add or remove programs
will my system automaticaly go back to service pack 2 or it will couse a problem and I will have to reinstall my system completely???

Thanks in advance.

Never had that happen here.

SP3 never took a speed hit but I've lost count of speed loss due to many of those antivirus suites.

Tell more.

I don't really know what details you need in order to find solution...

You offered a little but no name of the antivirus.

You don't really tell what your friend did.
- He installed SP3. From what source?
- If you install SP3 now, you need a few more hours to install all updates that came later. Did he do that?
- Did he install avira antivirus also? You only tell he tried.

Then tell something more about your PC:
- what CPU
- how much RAM

It's possible the system is slow because Avira does a scan at boot.
- Did he (or you) do a full scan of your hard disk after installing Avira?
- If you go to the processes tab of Task Manager immediately after boot, what 5 processes are using the most CPU?
