In the last two or three years Ive run Norton, McAfee, Trend, BitDefender, CA, Panda, ClamAV, Grisoft, Sophos and F-Secure, and Ive just installed Kaspersky. Im probably forgetting a couple of them too.
When they say familiarity breeds contempt theyre not entirely on-point. I dont stick with any of these products long enough to get familiar with them, and I hate them all. I havent really made up my mind about Kaspersky, which has an excellent reputation among the more technical anti-malware crowd, but in the two days Ive been running it Ive already had problems.
Heres something you might not have guessed, although it makes sense when you think about it. Malware researchers dont run anti-virus software. It gets in the way. I dont fancy myself all that serious a researcher, but I keep at least one machine without anti-virus software so that I can test suspicious files. If I need to scan something I just send it to VirusTotal, (one of the great research sites on the Net).
These days Im tempted to dump my anti-virus software as well, and I get a lot of viruses in my e-mail. Ive had bad luck with a lot of the software crashing my system, slowing it to a crawl at some points, and lying to me about when my license expires.
Ive had that last problem recently with both Norton Antivirus and Trend Internet Security. This blog thread and this one about Norton activation problems generated long threads of users saying, mostly, "me too!" Incidentally, I did ask Symantec about the problems and never got a response. Trend Micros Internet Security suite started telling me I had to renew about six months before the expiration date. I decided not to fight on that one and just move on.
CAs product gave me only about two months on my one-year subscription before it started telling me to buy another year. Time to uninstall and move on to the next one. You might have guessed I usually get eval copies of these programs. If I had paid I might be willing to spend more time trying to get tech support, but I have no patience for these things. I do usually buy anti-virus software when I buy a new computer, and I bought the copy of Kaspersky Antivirus Im using.
From there I moved to F-Secure Internet Security and quickly developed a problem: I have to use the Cisco VPN client for work and whenever I connected to the VPN on a system with F-Secure loaded (I tried this on two separate systems), the computer blue-screened and rebooted. F-Secure is still investigating.
