[citation][nom]beayn[/nom]Unfortunately a single scanner isn't enough these days. You'll want your usual installed AV scanner, Malwarebytes, Superantispyware, Spybot, ESET Online Scanner (If you don't use NOD32 AV). If you want to go all out, add in Dr Web free scanner, TDSS Killer for a common rootkit (ironically from Kaspersky), House Call from Trend Micro and GMER rootkit scanner. Then to finish it off, make sure things are clean with Hijackthis.The first 4 are usually enough, but if you're particularly bad (or good) at getting infected, use the rest listed.[/citation]
It is considered bad practice to run multiple scanners on the same computer. Pick one and stick with it!
