I am operating a Windows Home XP system.

I have tried to be sensible and hopefully get a good antivirus, so I have installed Norton Internet Security, and I have regulary done the updates, and everything seemed fine until about a month ago. Norton keeps telling me that I have a trogen called It starts by calling the trogen Generic 118, and it was first discovered, in June, it tells me to go to the online security page and it tells me this

Packed.Generic.117 is a heuristic detection for files that may have been obfuscated or encrypted to conceal them from antivirus software.

It also tells me to disable my restore on my computer, and to run its intellegent update, it then tells me to press the ctrl, alt and delete buttons, to open the processes window, and to delete a file called svchost.exc file, the trouble is that there are are 5 files which are as follows

1 svchost.exc which says its a system file which is 512k
2 svchost.exc which says it is a local service which is 8,120k
3 svchost.exc which says it is another system file which is 22,084k
4 svchost.exc which says it is a Network Service file, which is 5,724k
5 svchost.exc which says it is another system file which is 1,940k

I follow the instuctions, however I only get as far as deleting the first 3 files, and then whole computer goes to reboot, and the files seemed to be restored. No matter how hard I try to get rid of this, it doesn't want to go anywhere, and Norton seems to keep telling me its there, however one minute Norton is telling me this is a high risk and next its telling me its a low risk, I just can't understand what is going on.

Please could someone advise me what to do.

Thank you for your consideration.

Take care

Hello Petrena and welcome to BC :thumbsup:

Did Norton provide a File Path for the file in question?

Example: C:\WINDOWS\assembly\IEHost in which IEHost is a file, assembly is a folder, WINDOWS is a folder, and C is the disc the folder is on.

Multiple instances of SVCHOST is normal. Heuristic analysis can generate false positives. This means that a file is flagged as having an infection when in fact it is clean. When this happens, we get additional opinions on the file in question. That is why we need to know if Norton provided a file path.

Also, if you haven't done so already, please turn System Restore back on. Here at Bleeping Computer - unlike Symantec, we usually recommend that System Restore stays on until the computer is disinfected, at which point we flush the restore points.

Please let us know if you have the file path, and we will provide directions for getting the second opinion.
