What is a virus

Question

Hi,

My name is Jim.

I would like some help with "W32.BLASTER.WORM",which infected my pc a few days ago,like it did to many thousands...

I followed the steps indicated on Symantec's site and i think i managed to deal with the crisis successfully.

Still,i want to make sure,in order to avoid any unpleasant surprises !

1) It's my understanding that the virus came into my system without me downloading anything,but just by being on the internet.Is that correct ?

2) My Norton Antivirus software scanned 2 infected items,both in directory

C:WINDOWS\System 32

One of them was "msblast.exe",mentioned in symantec's directions.

The other was "TFTP812" ;I didn't see this one mentioned anywhere.Is this a file that the virus brought into my computer,or was it an existing system file that got infected ?

3) Is what symantec say in their directions,all that the virus does ?

Is it possible that it has deleted or altered anything else in my system or program files,that i don't know about ?

4) Would you recommend that i use the windows xp "System Restore" function,just to make sure that everything got back to the way it was ?

If i restore my system to an earlier point in time and i check the particular registry value that the virus altered,and it's ok,then that means it's a clean restore point,right ?

Thanks in advance for any help you can give.

Hello..

As far as i can tell you, you should be fine Good thign norton picked up on those viruses The second one you seem to have had on your system does not seem to be anything related to the Blaster Just makse sure you stay current with your updates and things of windows and norton Windows let out a patch to fix the vunerabilty that allows the blaster to come in to your system so i suggest you make sure you have that update It should be available on the Microsoft windows updates Make sure you stay current with those as well I dont think the Blaster worm deleted or corrupted any files everything on your system should be still in tact as long as all traces and variants of the virus are deleted As for windows system restore I dont see a need to use that And if you decide to do that you will loose any information you installed or saved up until that date you restored it back to

Well that is about it I hope this information has helped you

Good luck
