My computer performance became very slow after installing Eset smart security 9. Today I bought this product. Before I used ESET versions 6,7,8 but didn't face any problems. From last 5-6 months I'm facing this issue, I thought I used free version that's why having trouble but after purchasing license still facing performance issue. RAM using 3.90GB out of 4GB. Just now I un-installed ESET and my computer became normal as before.
