iexplore.exe constantly running - slow PC

Since doing a system restore I'm plagued with internet explorer windows popping up with adverts - a problem I never previously had. I've reinstalled Zone Alarm, Spywaregaurd and AdAware as well as AVG anti-virus and done full scans.

On occasions the PC runs very slowly (sometimes coming to a complete halt when I can't even get Task Manager to open). In task manager I've noticed that iexplore.exe is running (even though I have no Internet Explorer windows open) and that it is using 99% of CPU and about 80MB of RAM. If I end the process in task manager it just comes right back within seconds. Have I got a virus or spyware problem here?

Any suggestions to get rid of the problem?

Thanks

Joe R. - Messenger was running "in the background" (in system tray) but even exiting this made no difference.

setecio - sorry to be a cautious but what are these programs - my firewall didn't seem to like at least one of them

Those programs should only be used under supervision from an expert especially Combofix which has the power to wreck a computer in the untrained hands.
And you certainly shouldnt go using those tools without even knowing what is wrong with your computer.

Press CTRL-ALT-Delete to open Task Manager and under Processes see which are using most CPU

Sorry for delay - PC been refusing to start up again - until my son tried when it booted up first time!! Task manager shows that iexplore.exe is running (even though I have no Internet Explorer windows open) and that it is using 99% of CPU and about 80MB of RAM. If I end the process in task manager it just comes right back within seconds. Every 5 minutes or so I get one or more pop up windows - many prefixed by Cid.

I know I've got a dodgy CMOS battery (see seperate post) but it seems like there are several seperate issues.

I'm starting to wonder if its time to splash out on a new PC. Any thoughts?

Your firewall probably doesn't like combofix as it is often detected as a 'trojan'. They are all removal tools for several common pieces of malware that do what you are experiencing.

A new PC ? Well depends how old the current one is.

Another alternative is to save all your documents, photos etc and format the hard disc and reinstall windows, but that depends if you have the discs or a reset option.

But, despite what Mac70 says, I would recommend using the tools for scanning / removal. Leave combofix for the moment and see if the others detect anything.

Nearly 5 years old - Compaq Presario Athlon 2800+ 512MB RAM (DDR-SDRAM 333Mhz)80GB hard drive. When it's working properly it does most things we need OK - trouble is it's got temperamental and before the crashes started the cursor used to "freeze" for 10-15 seconds every few minutes which was very frustrating.
