I actually use 3 different types of anti-virus on several of my machines. Just to note, never run more then one per machine. Doing so not only messes up performance, it causes conflicts that leave you open to infections. That being said, I use Kaspersky, Trend Micro, and one I like to avoid but still use is Norton. Mostly because Norton lags my high end pcs. Reason I use different brands on different machines is some work better than others, and I was also having issues where one brand would cause BSOD on one machine when another it would work fine, and all my pcs I built myself. Well almost all. My kids built their first ones a few years back under my guidance. But as far as it goes, Trend worked great for me once I added not the file, but the whole folder to the exception list. Before I learned of CH, Id end up going to websites that the programs were not more of an issue, then the advertisements in them that were highly infected. You can easily get the versions that sell in stores like BestBuy that sell for $60 to $120 on Amazon or a trustful seller on Ebay sometimes for as little as $12 that will cover from 3 to 5 devices. Always buy the boxed version. Never ever buy the versions where they ask you for a credit card. That's one of their biggest scams where you get 6 months to a year for $40, and before you know it, renewal ends up showing on your statement from $150 to $200. Another scam you should be aware of are the free virus scans. Never let them touch your pc. Most people who go in to get this done, most likely had clean machines, but ended up leaving infected. Just watch next time your in one of those stores, and you see them take a flash drive out of one laptop, and put it in another. Whatever that PC had, will now be on the machine they run their software on. You most likely wont see the results of the damage till weeks later. Safest way to test for infections, are the packages that have a boot cd, that can load off the cd instead of the hard drive.
Also, if your pc is already infected, installing antivirus wont fix the issue. Many think it will. Best bet, is get an external hard drive you can boot off of, and install a fresh OS with antivirus, and boot off the external, then scan your drives to remove the infections. I make constant backups, so if I do get infected, I just format the drives, and reinstall the image I made. I got tired of trying to fix files to find out another was bad that did more damage than the virus itself.
