Hi true indian,

Could well be that bmp.exe is found up by avast flagged as PUP risktool. For safe variants of that media player tool see: htxp://www.backgroundtask.eu/Systeemtaken/taakinfo/30932/BMP.exe/
htxp://www.runscanner.net/lib/bmp.exe.html and
where this Chinese active malcode is being flagged as TR/FlyStudio.AI.1129, see: htxp://zulu.zscaler.com/submission/show/002b26f390d7be7416d1574ab05c8298-1337262299 avast does not detect it yet (possibly as PUP when run): hxtp://vscan.urlvoid.com/analysis/0cb2f654fd22256efa7ae84f2b8c9625/Ym1wLWV4ZQ==/
See Comodo analysis here: htxp://camas.comodo.com/cgi-bin/submit?file=84c90377421a63cfe767c17d7079877b7dab0f4c63d6b0d9f87ddb48e7a50360
Another variant of mentioned TR/FlyStudio.AI.1129 trojan-dropper is: File Name: shengguangtupian.ex-
MD5: 0cb2f654fd22256efa7ae84f2b8c9625
974890   AntiVir   2009/06/12 11:17:27 (CEST)
Meaning that bmp.exe is a 2009 variant trojan dropper that was resurrected and re-launched 2 days ago, so old wine in new sacks really,
reported the above to virus AT avast dot com for verification,

Not detected by avast: htxps://www.virustotal.com/file/528e5fe23f9208f9f3726fdcd794517d3df3eaaef4b055ef88017eb9bc9fadc2/analysis/
see: htxp://zulu.zscaler.com/submission/show/bad6c4bbfdb76b8cc8abeaf333ae3014-1337263557

A block should be considered because there are 18 reports of various  MSIL/Solimba application or Gen:Variant.Barys.2069 active from that domain &
bad host for 1 yr and 7 months on 896 appearances in spam e-mail or spam post urls.

Should be flagged as PUP, if flagged at all.
