I am running XP on older dell tower. recenlty I have had the buump.me redirect virus but has now been removed. The sound though is now scratchy, choppy and lags at times. I have had this before but i think just did a rollback to previous date and it dissappeared. I could not find a solution then and now it has returned. Is it a virus issue, corrupted driver, buffer issue? I have tried all the standard attemps to resolve but nothing to date. At times it is worst than usual but i get i through headphones and pc speakers. I have 2 profiles on pc and it is on both even though I rarely use the other. Any ideas?
