panda is great. in any shape or form, i am not telling you to use panda. it was a mere answer to the question. im guessing you are not using a full retail bought copy of panda titanium/platinum 2005 v4.02. maybe a copy or pirated cracked copy. as for the slow down, i never had any problems, at that may be because panda has "true prevent" where it is constantly scanning you computer for new threats and monitoring what files you bring in and take out.sho95 said:34erd is correct Panda sucks. It made every single computer at work slow down. One to the point that it would just not let you do anything. The program will use all the CPU. AVG did better it found virus that Panda did not find.computerhakk Just incase you ask all those systems have 512 of ram with is not great but works great just for office daily use.
