It can solve the issue. I received a trojan which Avast stopped. It
was still in the temp files upon a scan though and came up as
removable. Deleting the temp files solved the problem and it was no
longer on the machine.
Then you were fortunate, but there is no way to know the true
malware-status of the OP's machine. Most malware resides in other
places on the hard drive in addition to the Temporary files. Therefore,
I stand by what I said - the OP should perform the normal scans for
malware in a systematic way.
