Why isn't your friend posting this with useful information like quoted error messages and/or screenshots?

[ShadowFlame]

he doesnt know alot about computers this is his first computer ever and hes 18! it was a gift from his family he also isnt the best at reading and i have no idea what to do for him at this point thats why im asking the steam community

[Muppet among Puppets]

The computer is infected with a rogue antivirus.

[ShadowFlame]

yeah sadly his entire pc and crashed it when we ran another anti-virus he had to factory reset the whole computer it was the only way to save it but it works fine now but thank you atleast i know what the cause is now he didnt have very good anti-virus but hes getting better anti virus now his girlfriends going to buy it for him and he has a free trial of it right now so he should be ok were currently reinstalling steam and skype ect ect

Never use the AV That comes with the pc they are never anygood and more likely causes more problems then it solves.. Speaking from experiance.. Or anything "free" for that matter.

[Forcen]

Tell your friend to pay for sims 3 next time.

[ShadowFlame]
