Hey today i look in my task manager and i find a task called ‘‘WCD.exe’’
It sounds suspiciously and I Google the name.
I do not know how it got there and I saw it by a ‘‘accident’’

I could not find wcd.exe some places so I have had no a chance to scan it 
What to do :ii
Are you running a medical genome sequencing programme ?
wcd is an open source tool for clustering expressed sequence tags. It implements matching using either d2 or edit distance, which provides sensitive matching. Heuristics speed up the clustering process. wcd parallelises well under MPI and also provides Pthreads clustering. wcd has a very compact memory representation which means that large files can be clustered on a single processor (and it can run quite happily without MPI or Pthreads headers or libraries being available). Of course, if you have a 100 CPU cluster -- it'll go much faster!
Expressed sequence tag (EST) sequencing projects are underway for numerous organisms, generating millions of short, single-pass nucleotide sequence reads, accumulating in EST databases. Extensive computational strategies have been developed to organize and analyse both small- and large-scale EST data for gene discovery, transcript and single nucleotide polymorphism analysis as well as functional annotation of putative gene products. We provide an overview of the significance of ESTs in the genomic era, their properties and the applications of ESTs. Methods adopted for each step of EST analysis by various research groups have been compared. Challenges that lie ahead in organizing and analysing the ever increasing EST data have also been identified. The most appropriate software tools for EST pre-processing, clustering and assembly, database matching and functional annotation have been compiled (available online from http://biolinfo.org/EST). We propose a road map for EST analysis to accelerate the effective analyses of EST data sets. An investigation of EST analysis platforms reveals that they all terminate prior to downstream functional annotation including gene ontologies, motif/pattern analysis and pathway mapping.http://bib.oxfordjournals.org/content/8/1/6.long http://code.google.com/hosting/search?q=label:ESTs
