I am new to this site, although I have used it to evaluate AV software which I need to update as my current licence with Sophos is due to expire and I have no wish to pay through the nose for a product which offers very limited update facilities. I tried both NOD32 and KAV trial versions, and went ofr KAV because the demo version synched with my Outlook whereas NOD32 picked up Outlook Express only which I don't use. I removed the demo before purchasing KAV Personal Pro for close enough to $100 but for some reason it failed to synch with Outlook like my demo did. I e-mailed them and they responded fast but with useless advice. They sent me a registry cleaner which removed the programme and then asked me to re-install. I did that, then asked them where do I re-install from since I downloaded the programme from their website and I don't want to buy the programme again. They don't seem to have an answer which I find incredible. I paid $100 for this download, it didn't work like the demo and now I'm left with nothing. I would have went for Norton but I heard it had isuues with Win2000 which I run, so I went for something which appeared to test great on my system yet messed up once I stumped up for the full programme. Their tech support via e-mail has responded fast but ignored my main problem which is how do I re-install KAV Pro (which has been paid for) without the CD. This raises the issue of what happens if you get a bad download? Unless you've bought a boxed version of KAV it seems you are up the creek without a paddle. I hope they come up with an answer soon, because I spent quite some time researching before I bought this product and I feel badly let down.
