Hi. Just thought I'd share my recent experiences with everyone, and maybe get some kind of useful feedback. I was using F-Secure for about 6 months because it had a good reputation and incorporated AVP, F-Prot, and another lesser known AV. I assumed that it was able to utilise AVP and F-Prot to their usual extent. It would seem that is not so. I downloaded a copy of Tron.exe zipped and manually scanned it with F-Secure. Nothing. I unzipped it. Scanned the exe. Nothing. Yes the bases were up to date. I also notice that F-Secure didn't seem to do so good on some of the comparison tests so I decided to go back to KAV. I downloaded and installed KAV 3.6 first and had trouble with it unloading itself after it started up. Also had some other minor problems. I have Win2K SP2. I then tried the newest version KAV 4.0.6. Looked ok but found out it was really slow. When I opened my file manager, it took forever, unless I disabled monitoring packed files. Also it slowed down my surfing tremendously. Took forever to shut the computer down too. So. I ended up going back to version 188.8.131.52. It is working great. It is fast and stable. Also catches tron.zip as soon as I highlight it. That and all the other virises and trojans I have in my library. Here's the question part. Has anybody found a later version that is fast and stable? Anybody know if there is anything to the newer versions that make them better than the older version, or is it just bells and whistles? I fear that Kaspersky has made a big mistake in trying to make their AV compatible with that POS XP. Instead of coming up with a seperate version for XP because it is so different, they chose to stick with one version, and that was wrong. So, I want to stick with Kaspersky simply because it does such a great job of catching both viruses and trojans. I would like to have a newer version that worked well though and I wonder if anyone has any insight on this.
