If it doesn't come now, then re-enable each application at a time and trace out the culprit !!

and as its a faked file(not valid), so Download these tools and run them to delete everything they detect as BAD !! :)

Hi flekka,

msa64chk.dll is part of a very nasty dialer called MatrixDialer. Fortunately, it can be removed manually by following the instructions at:


Make a printout of that webpage for reference when you're doing the removal.

After you have removed it, download AdAware and Spybot Search and Destroy; those two are the best anti-spyware programs and offer good protection. After installing them, make sure you Update them both before running a scan of your machine with them. Preferably reboot the machine in between scans. You can download both from:


Also, remember to keep your Antivirus updated and get a Firewall if you don't have one yet. You sohlud also run Windows Update frequently. Mny of the holes these malware programs exploit have patches released by Microsoft. Welcome to EE.

Good Vibes!

Despite its humble beginnings, phishing has come a long way since those first crudely constructed emails. Today, phishing sites can appear and disappear in the length of a coffee break, and it takes more than a little know-how to keep your clients secure.

   SheharyaarSaahil and Lobo
    thanks for being so helpfull + quick to reply, eventually solved problem by keeping on at vendor,
    went through it step by step, very helpfull when you can get through, eventuall answer was very close to Sheharyaar's first answer, but split point's becouse Lobo's solution of removing manually following a print out will help in case it comes back (hope not)
         so i bow to your computing skills, stay handy + close, sure to need you both again,
                                   thank's again
            p.s.  Lobo have antivirus + firewall +do full scan every week, automatic updates set,
                     downloaded microsoft patches when advised, only got the SYSTEM32 ERROR
                    after downloaded microsoft service pack 2 (KB834707) could be a coincident
                    but makes me wary !

Hi flekka,

 Thanks for the points and the comment. It may sound weird, but I sincerely hope not to see you again in this forum... at least not with the same problem ;o)

Coincidentially, there are so many reports of systems going wacko after installing SP2 that I would no install it myself until MS gets serious about it and releases a patched version.

Good Vibes!!
