I just want to tell you a story involving several programs, and how difficult it is sometimes to tell what is happening to your system. In May this year I bought a boxed version of KAV + KAH at a large store in Milan, Italy(cost:50 Euros). KAV's version happened to be 5.0.156 and when I tried to upgrade to the latest version kaspersky would decline the upgrade on account of the license key being' blacklisted' (basically meaning my program has a pirate license). I e-mailed KAV support on the spot with proof of payment of my purchase (I sent the e-mail to at least 3 different addresses) and nevergot a reply. Well I thought, the program works well, so let's wait for the next yearly payment to ask for an upgrade(but I couldn't help thinking of Symantec's notorious support service). Now enter ShadowUser to this: Trialled the program, liked it, apparently no issues and bought it. After several weeks I realize that whenever I try to standby or hibernate Windows (Windows home XP2) I get a 'blue screen of death'. My immediate reaction was that something was wrong with Windows, and took my comp back to the manufacturer assistance for advice. Compaq said the Operating system was damaged (?) and there's no other alternative than reformat the HD. Got my comp back and felt as if I had lost my wallet, and wasn't convinced about Compaq diagnosis. I was going to re- install everything from scratch and did it methodically, I checked every program after download for possible blue screens. And bingo, after re-installing ShadowUser I got a blue screen when I try to Hibernate the system. I e-mailed Shadowstor straight away about the problem asking them to look into it for future reference. I got a reply within a day! They kindly informed me, without knowing anything about my system, that the problem is caused by an early version of ....KAV. And they were right! Upon uninstalling KAV 5.0.156 (which I could not upgrade nor could I get a single reply from KAV) my system behaved 'normally'. I tried to download the trial version of the latest KAV pro version. As predicted from the Shadowstor support, it behaved perfectly except that the program reported a mail scan error and suggested I SHOULD CONTACT KAV SUPPORT straight away..... No way, my patience has its limits, and as much as I like KAV,it's been the cause of too many of my problems and the bottom line is that many companies nowadays think they can get away with just supplying a good product without any support. I'm trying NOD32, so far so good, wish me luck.
