Hi > > I seem again to be at odds with everybody elses opinion ,But here is my story . I have been using my computer for internet access for the kast 3 years ( email,newsgroups and lists ; NO FTP ) . 9 months ago I did a defrag and all hell broke lose . I insisted it was a virus but was told definately notby computer knowledgeable friends . Various( 4) antivirus programs I tried named different viruses . The latest program I ran named it "parity boot.enc " and supposedly got rid of it . I cannot guarantee that it did not come from another source but there is a strong possibility it came from the internet as my computer gets very little from other sources . I prop[ose the following method of transfer( viruses require a method of transfer from file to file ). Object arrives at offline reader and attaches itself unanounced to your reader . There it sits waiting for the defrag . When you defrag it uses the frag prog to insert itself where it wants . I dont know if this is possible but I cant see why not . I am a little sceptical of this virus alert as this virus seems to have made some 3 mutations 1) get accross the barrier of the offline mail reader and into your computer 2) move easily from file to file in your computer 3)demolish all the files I however do not share the general view expressed in this list that one cannot be infected by email .Where there is a will there is a way . There is bound to be an email transferable virus sometime just as in my view there is bound to be a cure for all PD . peace Alastair ( [log in to unmask] )
