I've been running Bit Defender for about 15 months now. During that time two rootkits have found their way into my laptop with no detection from bitdefender, but today, I discovered that your product missed Luhe.Lockscreen.a trojan. My system was running like a dog for the last few days. I checked bitdefender was up-to-date (auto updates with no failures) and after two scans, it didn't pick anything up.
I uninstalled bit defender, and installed a free virus checker which picked it up in Program Data.
How is this possible? I'm really in 2 minds as to whether to use your product again. It only ever seems to detect cookies as being malicious.
