At last, it seems that I've found my Antivirus! after a long search! I used KIS for a couple of months before and hated how slow and sluggish my system became (check sig for specs). If I would launch like a large setup file with KIS, it would take like 20 seconds or so just for the file to start initializing the setup and decompressing the built in files. With that level of slow performance, and I also felt my browsing experience is kinda slow, so I switched to other AVs trying each one at a time and moving on I've read someone on the forums here advice to use KAV only minus the firewall, parental control, anti spam, etc.... so I did, and I am astonished by what a difference KAV made! It is very light on my system even when doing a full system scan it does it in like 7 mins and I have 700 GB of DATA! Futhermore, the system feels snappy just like when I had avast installed only this is more secure! I am so glad I did this move and I advice anyone who is looking for a good AV to give it a shot!
