Computer clean up

I've just found and removed 720 threats on the club computer! These must have come in on peoples memory sticks.
Please check your computer and download the following FREE computer clean up programmes which will remove any threats and nasty stuff on the computer. The threats which are called malware and slow up your computer are clever and bypass your firewall and your antivirus programmes.
These programmes are
1) Ccleaner from Piriform -
2) Malwarebytes from -
Ignore all the promotion stuff and go for the free download.
I suggest you download and run Ccleaner first as it removes the left over bits from your internet browsing - Ccleaner stands for crap cleaner! Then download and run the Malwarebytes programme.
The Ccleaner warns you that its about to permanently delete stuff but don't worry about that. They are both easy to follow and I suggest you run the programmes about once a month.
Crap cleaner won't take long, but if you're using a well used desk top computer, Malwarebytes could take a long time, ie hours!
