Make sure your Anti-virus ap is updated with the latest definitions and run a scan using safe mode.
Same for any anti-malware aps you have - update them and run them in safe mode.
You should use (at a minimum) AdAware and Spybot Search and Destroy.
If you do not already have those get them here:
AdAware SE: Get the freeware version even though they will continually offer you upgrades to one of their paid versions. Download it, install it, update it and run it in safe mode. http://www.lavasoftusa.com/software/adaware/
Spybot S&D: When you install it make sure you enable "Teatimer" as well. Update it before you run it, Set it to "immunize" your computer". http://www.safer-networking.org/en/index.html
Be sure to enable “Teatimer” which gives you realtime protection.
You may want to try Microsoft Windows Defender, freeware replacement for their Antispyware beta which came out yesterday.
"Windows Defender (Beta 2) is a free program that helps protect your computer against pop-ups, slow performance, and security threats caused by spyware and other unwanted software. It features Real-Time Protection, a monitoring system that recommends actions against spyware when it's detected, and a new streamlined interface that minimizes interruptions and helps you stay productive.http://www.microsoft.com/athome/security/s...re/default.mspx
Then run several web based av and anti-malware scans. Set them to fix what they find. Depending on your settings in Internet Explorer they may ask you to allow Active X - allow it:Web based online Antivirus and anti-malware scans:
(these can be run regardless of whatever else you are using. You must use Internet Explorer to run these as they require Active X to run).

Open your task manager (control/alt/del pressed at the same time) and look at what is using your system resources. The "choppyness" as you described is usually caused by something hogging resources - a process, an ongoing virus scan, etc.
Don't necessarilly shut anything off, but let us know what is using most of your resources.
Let us know if the problem continues after you complete the scans.
