Computer still slow after removing malware?

I play league of legends with my settings on very high and my graphics were not lagging, but now after I removed my malware it is lagging, not as much as when I had my malware. I was wondering if I still had malware on my computer, and how can I detect them?

to find out. I'm sure Broni or one of them would help you.

Verify that your DNS settings point to REAL and active DNS Servers, not proxys.

Use this link to download Win32Whois. Enter the DNS addresses (one at a time) to find who owns it and the domain name of that owner.

Then PING each DNS address to verify the system is running.

If you see timeouts, then that adds terrible delays in name resolution.
