Hi,
Recently my laptop is suddenly going on extremely performance all of a sudden while in the middle of browsing or working on Microsoft Excell. Suspecting a virus, I did some scans using PCTools, SuperAntispyware and lastly Mbam at differing times and/or days. Results show I did have some (posted the very last one here from Mbam) eventhough I cleaned and removed them everytime the scan results said I was infected. Why do I always get them???
Please help.... :'(
thanks in advance
Here's the mbam results:
