See if MBAM will find any malware that is maybe the cause of freezes:
Malwarebytes Antimalware (MBAM) http://www.download.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html
You can also download it from http://www.gt500.org/malwarebytes/mbam.jsp
Install MBAM then allow it to update and launch after installation.
When MBAM opens, select the "Settings" tab then put a checkmark for "Terminate Internet Explorer during removal"
Proceed in running a quick scan by selecting Scanner tab
+++++ If MBAM will not install, please rename the installer mbam-setup.exe. Example: newtool.exe
Proceed installing the renamed installer of MBAM.
+++++ If MBAM will not run, go to the program directory of MBAM (e.g. C:\Program FIles\Malwarebytes Antimalware\) then rename mbam.exe to newtool.exe, double click newtool.exe to proceed in running a quick scan.
+++++ If you can't update MBAM, manually download the database installer from http://malwarebytes.gt500.org/mbam-rules.exe

+++++ If you need to re-install MBAM but encounter issue in re-installing, try using the MBAM Cleanup Utility by downloading it from http://www.malwarebytes.org/mbam-clean.exe
NOTE: If any of it found infection, allow it to fix the computer. Reboot after the removal process. Re-scan the system until no more infection can be found.
Please scan in Normal mode, scan only using SAFE mode if the PC shutdown during scanning and/or removal process.
If no infection found, please check the Event Log viewer in XP for any system or application.
To bring up Event Viewer: Start>Run then type eventvwr.msc
Hit OK. Select "System" at the left pane. Review the logs at the right pane. Note the error logs (event ID, source, and details of the log) that you suspect as related to the freezes.
Do the same for "Application" logs.
My antivirus recently alerted me to a threat it caught called trojan.vundo, however I think it didn't actually catch it because my auto updates were disabled along with the mouse that the computer came with (HP Pavilion, windows XP). Lastly many pop-ups started. Ive run symantec antivirus in safemode and it found:
It appears to have dealt with them all because I was able to turn back on windows update, and more scans have turned up nothing. However I am still getting a lot of pop-ups if I leave my computer connected to the interenet. It will open internet explorer with a pop-up (most cases its from "Internet speed blah blah") and stay open a few minutes than close. I have ran the trojan.vundo removal tool from symantec and one you offered to others with the issue. Symantec found and elimnated one after that the second trojan.vundo found nothing. I just finished running the malwarebytes program you suggested and it found 13 more things so hopefully this has worked.
I wrote ^ about 2 weeks ago. Since then no more pop ups and no scans from AVG, Malware etc have found anything however the computer is constantly "freezing". It does not actually freeze because I can move mouse right click etc but nothing will open and If I have anything running it just basically stops responding to any commands. Any suggestions becuase turning the computer on and off all the time is getting old?
