I use McAfee virus protection and i think its working but i am not sure. I need to no because i am downloading a site like limewire and i want to know my comp. wont get a virus.

So here is the deal. Apparently, my computer is supposed to be "the fastest one in the house" (according to my dad). But when I was younger, I downloaded Limewire, And all sorts of different fonts and cursors from sketchy websites (I was young and stupid apparently).
Now, my computer is really slow. It takes about 15 mins to boot up, and it takes about 10 seconds to just respond to my clicks.

I have removed Limewire since then, and tried to get rid of all of the fonts and stuff, but that hasn’t really helped much.

I have Spybot and Symantec to get rid of spyware and viruses, but it is still so slow.

I would ask my dad, but I don’t want him to know that I had Limewire. >.<

Is there a software I can buy that can help me fix it? Or should I just buy a new hardrive and start over?

Thanks!

I’m having a issue understanding virus protection because I had a virus before and Dell tech team said I needed to reformat pc and I did. I downloaded viruus protection programs and aren’t them programs to remove the virus? Say if I downloaded a song from LimeWire what is the virus protection will do? Are the free AVG protections good or is better buying protections instead of getting a free version? Some sites I go to ads appear when closing, how can I prevent that do I need a spyware protection?

Ever since my mom baught this virus protection, my brother installed it (hes 20) and im 15, but im pretty good with computers, just not the best. Lol, Well, I lost limewire, and tabs, and now my computer wont recognize my mp3. It was a while back, but i really wanna add songs onto my mp3 and i want my tabs back, i dont care about limewire though. Can someone help me?

I deleted a video that I downloaded from Limewire and now I need to get it back. I’ve already used my CCleaner (a registry cleaner). Is it too late to retreive it?
