hi, i came to use my computer yesterday and it was running hideously slow. when i minimised any windows they didnt go to the taskbar they either sat on top of it or vanished completely. in addition some thinks i click on on the internet just do not appear. i looked in the msnconfig startup list to find nothing really odd looking. i then checked the task manager to find that my CPU usage was at 100% even though i had no open programs. i checked the processes list and saw that i had 2 SVCHOST.EXE process. 1 of these had 00 CPU usage and one of them has 99 CPU usage. i deleted the one with all of the CPU usage and my computer simply restarted itself. i then deleted the one with 00 which created some random graphics glitches and weird random fonts in menus. i was then advised by someone on a music forum that i post on, to do a HiJack This scan. this resulted in the log at the bottom of the post. He said that the smss.exe and lsass.exe processes could be linked to the flood.f trojan or the sasser worm. i was also told that the SVCHOST.EXE problem could be linked to the welchia worm.

i am running windows XP and have tried numerous spyware programs and virus checker packages including the symantec sasser worm and welchia worm fixers but my computer is still running terribly. i would be very grateful if someone could help me get back to running normally again. my hijack this log is below. thanks.

i have since found out that this is probably the welchia worm. someone on another forum posted a very similar problem with the welchia worm disguising itself as SVCHOST.exe and eating all the processor power.

i have now run the symantec welchia fixer about 6 times now and it says that the welchia worm is not on my computer.

anyone have any ideas of how to stop this SVCHOST.EVE chewing up my processor power?

hi, thanks for replying.

in the end i had to resort to formatting my computer to solve the problem as i was running out of time with university work and it seemed like the easiest and quickest way.

i will read that topic you posted though, as a precaution incase i come across this bug again.

i also now have installed the necessary fixes and patches to help prevent it happening again.
