I tried Avast about 8 years ago... and chose to go with AVG instead. I've been using AVG for all that time. For the past couple of months, my computer has been running VERY slowly, and there's been LOTS of HD access for no good reason. I was using AVG 2011. I began to worry about how "good" AVG was, which seemed to run like a bloated monster on my system. So I decided to uninstall AVG and try another Virus protection program. The first problem I ran into was trying to get rid of the horrible AVG program. I tried uninstalling it, and it came back. I tried uninstalling it from windows "safe mode", and it "came back" I had to download a special "removal tool" to get AVG off my system. FINALLY.
I tried two other virus detection programs, and they detected nothing more than AVG (cookies). Then I decided to download and try Avast;
After installing Avast, it immediately found 4 trojans. Then, when using the bootup scanner, it found 14 more infected files (trojans) mostly java related.
My system is running VERY smoothly, and there is no more HD access or system slow downs. Talk about SCARY that AVG would allow me to run my system with 18 trojans!!!! I will never again use AVG and I am sticking with Avast from this point foward.
I'm not sure if this is the place to post this, but had to tell somebody about my experience.
I'm now in the process of changing passwords to any sites I visited while infected with these trojans... just to be safe.
Thank you Avast. You have a wonderful program and a new VERY satisfied customer!!!
