Kaspersky is good (not real speedy) - except for those pesky objectID's and ISwift stuff - and after trying to get it off my machine (including using KAV's own utilities that did the job piecemeal fashion - I said never again.
Obviously someone as Kaspersky's got the hint that people don't want data hidden in Alternate Data Streams (the same technique rootkits use to hide from virus scanners etc, Kaspersky was hiding their data from virus and user tampering).
The current version apparently lets you opt out of "ISwift" but most users have no clue what it is, and probably won't discover until they try to remove it all.
What Kaspersky does, I don't believe is dangerous or harmful (it isn't) but I want to see what data is on my pc in plain view - I don't like anybody else hiding stuff from me, or deciding on my behalf that "I don't need to know".

Is the thread graylox was thinking of (if my powers or mind reading are as good as other people tell me).
As I said in the above link - the best (free) option is Avast (hands down).
I've had "discussions" in the past with support people from AVG I had a user send me a file she thought was OK - but AVG told her it had a trojan and mentioned something about banking. She panicked and sent me the file (who needs enemies, huh?) anyway I was ok for me - and it turned out to be a keygen for a commercial program (the filename said it was something entirely different). I pulled the file apart and watched it run and it was fine - no file or registry access, nothing left resident after it had ran. I wasn't a trojan & I was 100% sure of that. I forwarded it onto AVG and they told me it had a trojan, and I should not run it again and do a full scan of my hard disk because I was probably infected. I called their bluff and explained the detailed testing I had done, and they replied that "I shouldn't be running 'those' programs. We (AVG) are not going to mark it as a false positive, as our engineers have determined it to be an 'inappropriate' or 'dangerous' program".
So AVG is not only trying to detect viruses, but they are your moral guardian also - deciding what software you can and cannot run, and if you are naughty they will tell you it has a virus to "scare you off".
Now for a company to lie about a Trojan or Virus detection when that is the business they are in - is inexcusable - but it seems this is their policy. Use something else, that at least will be honest with what it "detects" and not also report on some ficticious "naughty, but harmless" list. (Maybe if they had an option to turn the BS filter off, it might be different).
I use NOD32, which isn't free, but depending on which testing results you refer to is either the best or the second best commercial AntiVirus for windows, available. (I value - High Detection rates (No BS), No False Positives, and Fast, Fast, Fast). Results: NOD32 vs. Competition
But as I have said numerous times before, don't become complacent about trusting AVG (paid or free) - there are other free alternative that are so much better.
Kaspersky is OK, but it can have high memory requirements (not sure about the current release, but previous versions certainly did), and it is definitely one of the slower products for on-demand scanning.
