Computer Slow Down [HijackThis log included]

Computer Slow Down

Hi

Have had this problem before and can't remember how i solved it the first time.

The problem is i suddenly have explorer.exe taking up to 99% of cpu and the memory via windows task manager goes up to 200mb!!

Had the following firewall alerts:

Back Orifice 2000 Trojan horse

Intrusion Detection:
MS_Windows_LSASS_RPC_DS_Request

Viruses:
Backdoor.Ciadoor
W32.HLLW.Chemsvy

all the above should have been dealt with via norton antivirus and firewall.

Have a funny feeling that MS_Windows_LSASS_RPC_DS_Request could be the problem but have windows pro sp1 up-to-date and norton up-to-date, so this shouldn't have been a problem?

Any ideas?

 

Norton isn't perfect and it also isn't meant to target Spyware and Adware. Check into the security forum here and you'll find some useful tools that may get to the bottom of your problem.

I would especially recommend AdAware, Spybot S&D and running SpywareBlaster (keep it updated). These meanies have a way of evolving and sneaking past the safeguards.

Try running an online virus scan - there are links to several from quicklinks in my signature. Norton may not be functioning even though it says it is running.

 

tried the online virus scan and found no viruses on my computer, but still have this problem of explorer.exe using 99% of the cpu after loading up a windows explorer screen.

already have spybot and adware, but no joy!

Any other ideas?
