Trojan:Win64/Sirefef.AA is a component of a Sirefef (also known as Max++ or ZeroAccess) rootkit infection, a PC threat that’s noted for flexible payloads and a multiple-component structure that’s often used to hijack your web browser or install rogue security programs. All components of a Sirefef infection should be considered potentially high-level PC threats, and Trojan:Win64/Sirefef.AA isn’t an exception to this general rule. Besides redirecting your online searches to harmful websites, Trojan:Win64/Sirefef.AA, by itself, may also turn your computer off at random intervals, forcing you to reboot manually. Other symptoms of infection by Trojan:Win64/Sirefef.AA and related PC threats may or may not be evident, and SpywareRemove.com malware research team recommends that you use powerful anti-malware products to remove Trojan:Win64/Sirefef.AA and other rootkit components.
Trojan:Win64/Sirefef.AA: a Very Special Browser Hijacker Just for Your OS
Trojan:Win64/Sirefef.AA, unlike many other Sirefef-based PC threats, is specific to 64-bit versions of Windows. 32-bit Windows OSes and non-Windows OSes can be considered safe from Trojan:Win64/Sirefef.AA, although the same doesn’t apply to all variants of Sirefef or similar rootkits. Because Trojan:Win64/Sirefef.AA and other rootkit-based PC threats (such as a href=”/removetrojsirefefkby.html” title=”RemoveTroj_Sirefef.kby”>Troj_Sirefef.kby, Win32/Sirefef.FY, Trojan.Sirefef.Ga, Win32:Sirefef-PL, PTCH_SIREFEF.L, Trojan win32:sirefef-sm and Trojan.Sirefef.BV) try to conceal themselves from visibility by infecting operating system files, you should use anti-malware programs to detect and remove Trojan:Win64/Sirefef.AA and its relatives non-hazardously.
SpywareRemove.com malware analysts have noted that Trojan:Win64/Sirefef.AA has two major functions, both of which can be detected manually:
- Trojan:Win64/Sirefef.AA can redirect your web browser’s online searches to irrelevant, unwanted or even malicious websites. These redirects trigger off of popular search engines, such as Google, Bing, Ask.com, Search.Icq.com and Yahoo.
- Trojan:Win64/Sirefef.AA may also turn off your PC under arbitrary circumstances (such as when Trojan:Win64/Sirefef.AA or a related PC threat detects usage of anti-malware scanners). However, booting your PC manually will the power state back to normal – until the next time Trojan:Win64/Sirefef.AA launches this attack.
Extra Reasons for You to Boot Trojan:Win64/Sirefef.AA’s Browser-Hijacking Posterior from Your Hard Drive
Trojan:Win64/Sirefef.AA’s attacks may be limited to the issues noted above, but SpywareRemove.com malware research team also adds that Trojan:Win64/Sirefef.AA is unlikely to be the only PC threat on any Trojan:Win64/Sirefef.AA-infected computer.

- Creating backdoor vulnerabilities that can allow criminals to control your computer for purposes such as stealing information or installing harmful software without your permission.
- Injecting malicious files into the memory processes of unrelated programs.
