Hello forum))
I’ve ran into a serious problem with two of our computers.
First of all, I have win XPsp2 here + avast home edition updated.
One fine day, I got a phone call, saying that two of our PC at work broke down. Both of them had similar problems: first of, internet connection wouldn’t work and Network connection’s panel won’t open(just a blank explorer screen); start up taking about 3min, even in safe mode; system restore won’t work, saying something about system not being secure and blah…; on one of PC’s i found modified host file, blocking all of the AV sites; Explorer won’t work later then(hangin up every time trying to open My computer); The system got very unstable and eventually comp[letly unusable.
I have scaned the system with: Hijackthis, Ewido, spyboot, Avast itself and its freeware cleaner tool. NONE of them showed up that something is wrong.
Then I have reinstalled Windows over the previous installation(upgrade mode) - didn’t help much, still no internet, weird behaviour.
P.S: I’ve looked up the Avast’ logs and mentioned that it has removed new.net(whatever it’s called) during the full scan. I’m aware of the problems that adware might cause, so I have successfuly ininstalled it - no effect on internet connection, still doesn’t work.
IS THERE A WAY TO SAVE THE SYSTEM WITHOUT FORMAT C: ?
any help would be very apreciated!
Sorry for being stupid, but are you really sure new.net could cause such a disaster?
And say I didn’t remove it properly(I’ll look into it now), how do I know it’s the only nasty thing that is left? How can I be sure my system is not totally exploited?
Forgot to mention, windows still boots up for like 2-3min.
Sorry again if I didn’t grasp something right away - I’m really tired - 7 hours of troubleshooting…
edit:
Now I have installed video card drivers and rebooted and computer got back into the same state as it was: buggy GUI, windows dissapearing, long system boots, desktp icons disapeared, Exporer doesn’t work…
Just read the posts (and associated links) in the link I gave which are showing it integrates itself and if improperly removed it breaks the windsock connection set-up.
Thank you for your time!
Still no luck(((
Read that link you gave me(I think I’ve already seen it before), ran lspfix and it didn’t show any components under remove tab.
I have noticed that if I leave the computer for like 5-10min then it will unfreeze, explorer will open…
PS:
My point was, how can broken internet stack case such a mess to the system start up and behavior, I still didn’t get it. You do not suppose this could be a virus, especially if it poped up at the same day on two computers joined into LAN?
I don’t know, I was thinking if you had a direct internet connection which is trying to be established if there was a problem perhaps that may cause delays, although this is an area that I don’t have much experience.
If avast detected them there is little reason to email them to avast, unless you have tested and believe one or more was a false positive detection.
Once in the chest they can do no harm and should it be necessary they can be recovered. So there is little point in sending them to the chest only to delete them from there immediately.
There is no rush to delete anything from the chest, they can’t do any harm there. Anything that you send to the chest you should leave there for a week or two. If after that time you have suffered no adverse effects from moving these to the chest, scan them again (inside the chest) and if they are still detected as viruses, delete them.
Have you read the other information in the links I gave about repairing windsock (LSPfix) ?
