my dell laptop had a "Alpha Online Scan-..provided by dell" popup. had 11 high and critical item come up. but when clicked the erase infections bar up pops the "file download-security warning" box. the Name is; Alpha-Scan-bc409e-2009-1938.exe, From; mycomputerthreat03.com, type: App.,160kb. Is this for real or just another way to download some other type of malware or viruses?
