WINSERVN caused an invalid page fault in module WININET.DLL
Installing by "PurityScan". AdAware will detect this foistware.
I installed "PurityScan" for testing purposes and report the following:
Executables used by PurityScan
lsem.exe and winservn set to run automatically via the registry key:
lsem is listed as "Amac". winservn.exe is listed as "ContentService".
lsem.exe can be found at ..\documents and settings\<username>\application data\lmserv.exe
winservn.exe can be found at ..\windows\system32\winservn.exe
sear1 continued to connect to the internet even after purityscan was shut down.
Uninstalling PurityScan removed winservn.exe but did not remove lsem.exe
Manual removal instructions:
Uninstall PurityScan (there is a download link for an uninstaller in the PurityScan scan window).
Use Task Manager (ctrl, alt, del) to shut down lsem.exe
Delete the reference to lsem.exe (Amac) at the registry key:
Delete the following registry key entries:
You should check for
further spyware/hijackware/foistware. Go to IE tools, internet options, general
tab. Click on the cache settings button and then 'view objects'. Delete anything
you don't recognise. If you are unsure, or no objects appear, for diagnosis
purposes I REALLY like BHODemon, available at
http://www.definitivesolutions.com/bhodemon.htm It does not need
installing - simply unzip and run the EXE programme. It is very easy to use.
I find this programme is a better option than IE6's ability to turn off "Enable third-party browser extensions (requires restart)". This disables *all* plug-ins and makes troubleshooting very difficult.
Many people like AdAware, available at www.lavasoft.de . Make sure you keep the signature files up to date and remember, AdAware may only remove the
current installation of spyware; it may not do anything about software that reinstalls itself, so unless you want to get stuck in an endless loop of hijack/cleanout/hijack/cleanout make sure you get rid of whatever is installing the junk. See my Troubleshooting advice for information about how to track down and get rid of spyware completely.
An excellent replacement for AdAware is Spybot. Again, it is a free programme which can be downloaded from:
