Suddenly, with no noticeable cause, the icons in explorer can’t be dragged and droped. I thought first it was a graphical problem, but when I try to paste it, paste appears disabled in the right-click menu.
Later I found that it was not only my PC. Other people had the same problem (no connection between our computers). Norton Antivirus and others av don’t report anything. The solution is simple: restarting Windows does the trick.
Very weird. What do you think? Some kind of strange mutation or what?
I had a rather similar problem on an older machine of mine; I couldn’t drag anything to a folder in Windows Explorer’s left-hand pane - the cursor would change to a barred circle. I believe it was related to a problem with some of the system folders (I had previously managed to delete the My Documents folder (which wasn’t supposed to be possible) - in the end, a complete wipe and reinstall of Windows was the only way I could fix it - not that I particularly recommend this.
I don’t have a definitive answer but it may be a resources problem caused by a common driver - do the PCs in question have the same video cards for instance?
You used to see this sort of thing a lot with Win3/95/98 when the heaps ran out of space.
This sounds like classic Blaster activity.
You may not be infected but you may be being hit.
The resart is easily explained by the traffic hitting you from another infected system.
If it occurs again have a look at the resources being used by SVChost.exe (also consider using F-Port from foundstone to have a looksee at teh ports in use )
Make sure you patch the box to stop it happening again.
Yes! Norton suddenly reports me that it found blaster in a strange file in Winnt/system32/tftp or something, it says the virus has been erased but svchost suddenly pops an error dialog.
How can I have a look at the resources being used by SVChost.exe? Please explain with more detail… thanks in advance.
Screw the SVChost files stuff. That’s only if your interested in the beastie itself
I’m going to recommend that you use Windows Update and install all of the “Critical Security Patches”. Personally I am staying away from SP4 , it’s caused me no end of grief. It does not contain all of the current patches.
What you’re seeing is indicative of SVChost having crashed out. This is often the result of the Blaster virus infecting, or trying to infect, your Win2k.
Removing the virus isn’t going to help you unless you patch your computer to prevent future infection attempts. Somewhere, probably on the same network or ISP, there is a computer spewing Blaster out and it’s going to keep causing you the same problem until you apply the patch.
The patches will shut down the vulnerability that allows your system to get hit (infected or not) by Blaster traffic. You can confidently apply them in the knowledge that they are simly fixing the Tiny File Transfer Protocol (TFTP) hole. They are certified and delivered by Microsoft so go for it.
Fixwelch and fixblast will try to find either virus on your systems. If they do they will fix it , if they dont they do nothing .
