If you're getting ads, pop ups etc from sites you visit e.g. screwfix, then clear your cookie's everyday.

Screwfix is simply using the cookie stored on your computer to show you adverts based on what you have been looking at, currently mine shows a pile of ads about cordless drills.
Not a virus more likely flash playing up and locking up the computer by holding the computer's focus and probably maxing out the processor, thus causing the processor to become unresponsive.
Not to be rude about your expert tom, but I'm wondering how much he actually knows....could be spyware, but personally I would have tried uninstalling flash fully and reinstalling it.
Failing that if you use firefox, try an addon called "adblock plus", which blocks the ads (will deprive chez of the click throughs, however if it means you can use the site without crashing your computer, it might be better to have your knowledge than the minorly decreased ad revenue)

hi dave, yes i still have AVG, so my expert computer man is not so expert after all, no dave he did't leave any instuctions only to run the malware every week,
p.s i only just sussed this thanks button, sorry to the above posts for not using it before

No video and definitely NO HAMMERS:

Malwarebytes Antimalware or MBAM Instructions.

To open MBAM, double click the shortcut on the desktop, or
Use Start -> All Programs -> Malwarebytes -> MBAM (red square with ‘M’in it).

Click Update Tab

Click Check for updates

Click OK when updates completed.

********************************

Click Scanner Tab

Put dot in ‘Perform quick scan’

Click Scan

Will take about 3 to 5 minutes to complete the scan.

When the scan is complete, if nothing is found it will show ’No malicious items found’ click OK. Or if it finds anything click Show Results to view the results.
Be sure that everything is checked, and click Remove Selected.
When completed, a log will open in Notepad. Save this log to My Documents in case it is needed for reference.

thanks all for your help.

tomplum, I don't know the hardware specs of your machine, but at home I often surf the web on a fairly old, low powered laptop. If I have 5+ tabs open at the same time, all with flash adverts etc. I can see the CPU is working, but it never gets to the point where the mouse jerks around the screen. If I have just UHM open, the CPU is almost always at 0%. Maybe something else is running on your machine, which combined with the load of flash is causing the problem. You can check this in Task Manager.

First ensure you're running the latest version of Chrome by installing from http://www.google.com/chrome/ Chrome has Flash support out of the box. Check you have hardware acceleration for flash enabled, see here http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html. The difference this makes will vary according to your hardware, but it's worth enabling anyway.

The next time you get the problem with your mouse check in Task Manager to see what processes are using the most CPU. To do this right click on the clock in the System Tray and choose Task Manager, click on the Processes tab and tick the box below the list of processes called Show processes from all users. You can click on the column header called CPU to order the processes by the percentage of CPU that they're using (You may need to click it a couple of times to get the process using the most CPU at the top). The Image Name column tells you what's using the resources. Post back the process that are using the most CPU when you have the problem. If you want a practice run in using Task Manager, start a manual virus scan of your computer in AVG, then open Task Manager as described and you'll see an AVG process using a large amount of CPU as it scans your machine.
