I have tested various Security software both "free" and "paid for" on Windows7... and can report the following..AVG Free and Avira's most recent versions work well without any negative issues..and Kaspersky Anti-Virus 2009 which is my personal favourite "paid for" version works faultlessly. PCTools free Firewall and Anti virus also behaves well on 7! On the whole...I've found Windows7 to be very "easy going" in its' acceptance of the many and varied applications I have tested on it. Bear in mind though..Its the old story....it can depend a lot on what other software that users may have added to their machines too! Developers do a decent job overall of attempting to make applications that will coexist alongside each other...but if you look at "user reviews" on download sites..you will always see that some users will praise certain software ..and others won't allow it near their machines. The Security programs I've stated above ...have all performed well on the three test machines I've tried them on..but a lot is down to personal taste too .Some beginners have trouble with Kaspersky 2009 and others struggle with AVG and Avira...So...if you are happy with the interface and the ease of configuration ...and virus detection capability of any of the above ..then any of these work quite happily on 7..Hope this helps?
NOD32 AV v4 works fine. I've found 7's UAC much less intrusive than Vista's; I haven't felt the need for Norton UAC so far and I've been doing a fair amount of admin tasks since upgrading Vista Business to 7 Enterprise on Friday - Vista would have driven me mad with UAC prompts in the same circumstances. 7 allows you more control over UAC too - a choice of 4 settings if I recall; I haven't felt the need to adjust it yet.
I have to agree with tigertop2 on the PCTools issue.I was always a big..big fan of Peter Nortons' programs ..then along came Symantec and screwed them with the "deep hooks into the registry" stuff ..I have long since decided that Symantec will have a job on getting my support back.The PCTools suite does run very sweetly on Windows 7 ..Lets' hope it stays that way eh?
I tried Panda Anti-Virus from the suggestion Page of MICROSOFT after installing it on 3 occaisons MICROFT did not recognise it and they said I should go elsewhere. Well if it a'int no good why recommend it. But then that's MICROSOFT>
