Honestly with the amount of spyware and bugs out there you really need to get some protection on your laptop...There are so many free programs that are just as good if not better than the paid ones...
With that being said try this fix...

Then install yourself at least 2 or 3 anti-spyware programs and only one antivirus program...Here are some choices....
Anti-virus:
avast! AVG free Avira Antivir Antispyware etc: Ad-Aware __(FREE) Spybot - Search & Destroy __(FREE) AVG Antispyware (formerly Ewido)
Once you have done that run a full system scan with your AV and then run the Anti-spyware programs....Remember to update them before running them...
If you still have problems after that you will need to post your situation at one of these forums for further assistance...
