Hello, I'm relatively new to Avast and posting to forums, so please forgive me if I am not doing this correctly. Is this an appropriate place to add to this conversation by saying since I updated to the 605-1 on Avast Home 4.6 Compile date 1/30/06 I have noticed a problem very similar to this one but with a twist. While downloading files from newgroups on a 1.5Mb/sec connection, I have seen my download rates drop from around 900K ~ 1Mb to 100K ~ 200K with the program AshMaiSv.exe taking anywhere from a prior 30% cpu to now 60 ~ 70% cpu leaving not much room for other things to be running. For me, this is not normal, I usually have around 45 processes running and didn't run into this until the update of Avast yesterday evening. Turning off the NNTP scan from the Internet Mail -> Customize settings, then re-connect BNR2 (my newsgroup grabber), and then no problems arise out of cpu usage. I realize this is becuase Avast is no longer scanning the NNTP streams, however, it has run...and scanned the NNTP services for a month without taking up so much cpu. Has anyone else seen this sort of thing happening?
